Cut edge corrosion demystified

The silent threat: early detection of cut edge corrosion

This type of corrosion affects the cut edges of a metal roof sheet. Nowadays, the majority of modern industrial units are built using profiled metal roofing. This is a tough material with a long lifespan between 40 to 60 years, ideal for prolonged exposure to the ever-changing British weather. However, a profiled metal roof still has its weaknesses.

Metal profiled sheets contain a steel core, and they have a protective surface coating, which is usually plastisol. Made of up fine polyvinylchloride (PVC) particles, which are suspended in liquid plasticiser, plastisols also include small amounts of pigment and stabilisers. This material is a highly durable, weather-protective layer, ideal for industrial roofs.

When the sheets are fabricated in the factory, this can leave a cut edge. Over time, the steel core can become exposed to the elements through the cut edges, causing the metal to rust. As a result, cut edge corrosion can occur, affecting the integrity of the metal sheet. When left unchecked, this type of corrosion can compromise the entire roof.

Therefore, early detection of cut edge corrosion is important if you want to maintain the longevity of your metal roof and your maintenance budget.


How to spot cut edge corrosion

Below are some common signs:

  • Look out for signs of rust appearing at the cut edges of the metal sheets. These may appear as reddish-brown streaks as well as spots. Regular roof inspections will ensure that any small areas of rust are detected before they spread further.
  • Look out for peeling and blistering where the protective coating has worn away at the cut edges. As the steel core of the metal edge will be exposed, this can lead to rust developing. It’s recommended to treat the cut edge before any corrosion occurs.
  • Look out for damp or stains inside the building, where water has penetrated through the roof. There could be a small leak where the cut edge has corroded to the point where it is allowing water ingress within the building.


If you suspect that the integrity of the metal roof sheets has been fully compromised, a full roof survey will need to be carried out.


How to treat cut edge corrosion

Cut edge corrosion must be treated as soon as possible to prevent costly repairs. Early detection of this type of corrosion will enable you or your client to address small areas of concern before they turn into big problems.

But before any treatment can be applied, the substrate must be prepared correctly. This is essential because the product might not adhere correctly. Mark Smith, one of our regional Technical Services Managers, has shared the following guidance:

“Make sure the substrate has been thoroughly cleaned and mechanically or manually prepared to the specified standard. Application must then follow the correct guidance and carried out in the right temperatures.”

Guide to industrial roof inspections

Common industrial roof issues

Before carrying out an industrial roof inspection, there are a several key areas to consider:


Defective roof flashings

Weather conditions and age can lead to roof flashings becoming damaged or defective. Seasonal temperature changes can also make flashing warp and rust. Extreme wind or rain can put pressure on weaker flashing. Past roof repairs or inspections may have caused dents or cracksThe flashing fillers can also fallout and degrade, this will allow driving rain to enter the building. When the flashing is no longer able to protect the roof seam, this can cause water ingress, increasing the risk of leaks.


Sealant around roof fixtures

If the industrial roof features rooflights or air conditioning units, there may be deterioration around the sealant used around these fixtures. If there are any gaps, this can lead to water ingress, resulting in leaks and damage within the building. Silicone sealants will deteriorate over time and can also be susceptible to bird attack, leaving problem areas that will need identifying in a roof inspection. 



Roof sheets are attached to the main frame and purlin`s using roof fixing screws, overtime these can deteriorate, rust, and become loose. They can also be incorrectly fixed and cause water ingress problems. It is prudent to check them for levels of corrosion and potential replacement to maintain a firm, secure seal. If they are still in good general condition, you can deal with the surface corrosion and re-seal using the Giromax basecoat and Giromax Roofcoat. This can be done in isolation or as a full roofcoat project.


Rooflight deterioration

When rooflights are manufactured, they come with a factory standard layer to protect against UV rays and weather conditions. Over time, this protective layer can start to deteriorate, resulting in weakness and poor thermal performance. It’s important from a buildings regulation perspective to ensure rooflights are compliant and meet the necessary criteria. One recommendation could be to repair and recoat the rooflight.


Cut edge corrosion

This is a common issue which affects the cut edges of the metal sheet. The factory applied coating can begin to peel and, when the edges are exposed, this can cause the metal to rust. Over time, cut-edge corrosion can affect the integrity of the metal sheet, compromising the roof itself. It is recommended to treat cut-edge corrosion as soon as possible to prevent costly replacements or dilapidations.


Roof coating condition

When you are carrying out roof inspections, always check the integrity of any existing or factory applied roof coatings. Depending on the type and quality of coating used, look out for blistering or areas where the coating is beginning to peel. Extreme heat, heavy rain or ice can damage and corrode poorer quality roof coatings. Check when the sheet was produced, or the coating was applied to see whether it’s over the guarantee period.


Asbestos cement issues

Asbestos cement was commonly used as a roofing material in the past, and this substrate comes with its own hazards and safety risks. Look out for cracks or corroded bolts, and never disturb the sheets, as this could release dangerous asbestos fibres. It’s usually recommended and much easier to recoat an asbestos cement roof, rather than replacing it. Full removal will require a costly, specialist asbestos company.


How to inspect the roof

A standard roof survey to check the condition should begin by assessing the building itself and any challenges. Start inside the building to identify any problem areas, such as damp spots or leaks. The type of checks required will depend on the type of building. Many industrial buildings contain offices, for example, prevent easy visibility of the internal roofing structure. In such cases, closely inspect suspended ceilings for watermarks, damp or mould.

The external roofing substrate and structure will need to be examined. This will help to determine whether there are any roof defects, potential areas of water ingress, or other issues, such as cut-edge corrosion. Depending on access and the size of the building, it may be safer to use a cherry-picker. Avoid stepping onto the roof unless you are clear on the weight load.

Once the roof inspection has been carried out, a detailed report should be produced outlining any issues and areas needing to be addressed. In terms of profiled metal roofing, this might include the thermal performance of any existing coatings, and whether these have deteriorated. Along with resistance to weather and UV rays, thermal efficiency is an important indicator of a good quality roof coating.


Ask the experts

We advise keeping detailed and thorough records of any inspections, so you can provide clients with a comprehensive history of their building’s condition. Maintain clear and consistent communication with your clients, including regular updates on the status of their buildings and any recommended actions. If your client needs their roof treating, repairing or recoating, then ensure you refer a reliable firm (we can provide a trusted list of contractors).

If you are in any doubt when it comes to any aspect of a roof inspection, please speak to our team. At Giromax, our experienced Technical Services Managers can advise on any aspect of treating an industrial roof. Our range of roof coatings protect the integrity of industrial roofing systems, as well as treating common issues such as cut-edge corrosion.

Successful strategies for industrial building maintenance

Whether your client is a commercial landlord or a tenant, it’s important to make sure everyone knows their responsibilities in terms of building upkeep. There are also various health and safety factors which need to be considered in a maintenance strategy.

Developing your building maintenance strategy

When developing a suitable strategy, carry out an audit of the building to determine and prioritise any areas requiring maintenance. List any problem areas, and what’s needed in the short term to address any issues. Consider the long-term impact on any business activities within the building that could be affected. Build a timeline that covers any repairs and include any key maintenance goals.

A tactical annual plan needs to be produced to prioritise works, either throughout the year or on a yearly basis. Categorise each area and allocate a budget, so you can create accurate financial forecasts. Through tactical planning, you can then allocate enough funds and resources to cover repairs. This will also help you to assess any health and safety considerations, allowing you to take appropriate action, if and when required.

Ultimately, a maintenance strategy can only be successful if everyone in the building understands their responsibilities. Set some objectives to identify key areas of focus, for example, contractual dilapidations relating to a lease. A copy can then be given to tenants to remind them of their own obligations.

As every industrial building has its differences, your maintenance strategy must also be tailored to reflect the type of building structure. If you manage a business that owns its own premises, then it’s important to know how your maintenance plan will affect your operational costs.


5 things to consider when planning maintenance

Below are five areas to factor into your planning, when you or your client are developing an industrial building maintenance strategy:

  1. Health and safety
    Health and safety must be the top priority of any building owner or landlord. When a building is poorly maintained, this can create safety hazards for employees, as well as potential compliance and legal issues. A buildings maintenance strategy will help to keep workers safe and ensures business continuity. Check any relevant safety regulations and building codes.
  2. Preventative measures
    When you prevent problems from occurring, businesses can protect their production or work schedules. Build time into your strategy for preventative maintenance and essential works, liaising with all businesses located within the building. By factoring in planned maintenance, you can give commercial tenants enough notice so they can adjust their work schedules.
  3. Maintain productivity
    Unexpected and unplanned downtime can lead to costly delays for a business, especially manufacturing firms. Strategic planning gives you greater control over your schedule, and businesses can plan maintenance tasks during times when it’s less disruptive to their operational activities.
  4. Building integrity
    A proactively maintained building will remain in good condition. Many industrial buildings have aging infrastructure, so strategies are needed to address such issues, such as asset management plans and phased upgrades. Planned maintenance will help you or your client to preserve the longevity of the building. Preventative maintenance ensures a safe premises and stability for any commercial tenants.
  5. Cost savings
    A buildings maintenance strategy will reap various long-term financial rewards for the building owner or landlord. Contingency planning will prepare you for any potential crises, such as environmental disasters. Strategic planning for preventative maintenance could result in significant cost savings. It’s much cheaper, for example, to preserve rather than replace cladding and roof systems.


Interior inspections

When it comes to the fabric of the building, it’s important to make sure the exterior is kept in good condition. But it’s also essential to factor in interior maintenance too.

Below is a high-level summary of key focus areas:

  • Fixtures and fittings, equipment and lighting.
  • Utilities – power, water, electrics and gas.
  • Walls, floors and ceilings.

Some of the above areas will require the services of professional qualified tradespeople. So, it’s important to make sure any annual safety checks are incorporated into your plan. Always included a fire risk assessment in your maintenance strategy.


Seek technical advice

A well-developed buildings maintenance strategy will allow you to be proactive instead of reactive. Preventative maintenance is always better than corrective repairs. Building owners and landlords can protect their premises, and business tenants can align maintenance plans to their operational activities. Many areas of an industrial building, including rooftops, can be easily repaired using high-quality coatings, reducing the need for a costly replacement roof.

At Giromax, we have a team of experienced Technical Services Managers who can advise on different coatings for your industrial building. Our range includes cut-edge corrosion treatments, gutter coatings, and coatings for profiled metal roofing and asbestos cement.

Industrial and commercial guttering challenges

Industrial roof gutters

Many gutter systems used on industrial buildings tend to be made from heavy-duty materials, such as galvanised steel and aluminium. These types of gutters have a typical lifespan of around 20 years. For older buildings and factories, it’s common to find guttering made of cast iron, concrete or asbestos cement. Each substrate has its own set of challenges in terms of corrosion or being susceptible to cracking.

The cost of replacing an industrial guttering system can be high and will depend on the material and building size. As an example, aluminium guttering costs around £25 per metre, while steel is around £30 per metre. Therefore, the cost of replacing an entire guttering system on a 10,000 square metre building could run into tens of thousands of pounds.

Commercial roof gutters

When it comes to commercial gutters used on office roofs, modern buildings may have similar systems as residential homes. Typically, this type of guttering would be made of PVC with a lifespan of around 20 years. But in the UK, many offices are found in older buildings, where heavy-duty cast iron gutters are present.

If an office is in a listed building, any replacement guttering would need to be like-for-like, in line with the relating conservation guidelines. Cast iron gutters can costs as much as £65 per metre, which can be a considerable outlay for a business expense.

Where offices form part of industrial units, similar costs for replacing commercial guttering might apply, such as galvanised steel or aluminium. As a guttering material and asides from PVC, aluminium is the lightest material and the easiest to install.


Environmental challenges

Climate change is posing greater challenges for commercial and industrial gutters. Heavy downpours of rain are placing huge pressure on guttering. Pooling water can build up quickly after a storm, along with any debris that has been brought onto rooftops by high winds. The force of water and objects can add weight to gutters, causing damage to weaker systems. Downpipes can also overflow, placing pressure on areas around the roofline and below.

Another cause for concern is extreme heat during the summer months. Hot conditions can damage guttering, causing it to expand and sometimes crack. UV rays can weaken the surface of the guttering and existing coatings, affecting the integrity of the gutter system. Therefore, guttering systems need protection to combat the effects of climate change.


Inspecting gutter systems

Whether you’re inspecting industrial or commercial guttering, a similar maintenance approach is required.

Below are a few tips for carrying out maintenance checks:

  • Inspect guttering after heavy rain or stormy conditions. Debris such as fallen leaves, twigs and branches can quickly accumulate and cause blockages. This puts a strain on guttering and downpipes, which can overflow onto cladding. Water can penetrate any weak spots in corroded cut edges of the roof and the building walls.
  • Where buildings are surrounded by trees, more regular inspections may be needed. Aim to cut trees back by around a metre from the roofline to ensure a clear gap between guttering systems. Some gutters have snowguards and cages to protect against fallen debris, bird nests and adverse weather conditions.
  • Check guttering for any micro roots such as moss, algae and lichen. Organic matter can grow quickly, leading to blockages. Remove using a fungicidal wash and clean thoroughly with water, while observing the correct jet washer pressures for the substrate. A water flow test is a good way to assess whether the gutter system is flowing correctly.
  • Carry out repairs as soon as possible to preserve the longevity of the guttering system. Giromax® Guttercoat is a moisture tolerant formula, which can be used to repair and encapsulate the surface, creating a protective barrier. This innovative solution helps to protect gutters from weather conditions and extreme temperatures.

Giromax® Guttercoat

When it comes to industrial or commercial guttering, the key is to perform regular maintenance. Use a drone to carry out cost-effective roof inspections, and repair or replace any damaged guttering to ensure the integrity of the building. By using a protective gutter coating, you can help to extend the life of your roof gutter.

Giromax® Guttercoat can be used on a variety of different substrates, including galvanised steel, aluminium, cast iron, copper, asbestos cement and concrete.

Why we do much more than BBA testing

Giromax® roof coatings are all BBA-approved, which means they have achieved British Agrément Certificates. But although we adhere to the BBA testing process, our technical team have their own rigorous testing process. Our approach greatly exceeds the number of tests required for a product to become BBA approved.


BBA approval inspection testing certification

The BBA is a recognised body that works closely with the construction sector, including the manufacturing of materials. Established in 1966 by the UK government, they are an independent certification organisation, which inspects the quality of work and materials. BBA certification is recognised by local authorities, building control, insurers and architects. BBA-approved products must meet a set of standards and are subject to regular inspections.

The BBA has a Test Services facility, which is a UKAS-accredited testing laboratory and ensures extra validity. Any materials used in construction, including roof coatings are tested to see how they will perform when exposed to extreme heat or cold and weather conditions.

When it comes to products, the BBA provides 1,000 hours of testing as a standard. They will test for product durability, thermal performance and energy efficiency. The BBA also performs weather resistance and wind testing to see how the coating fares in different conditions. They will also assess the mechanical, physical and structural elements of a coating to see whether the product performs as per the specification.

In comparison, the Giromax® technical team test our roof coatings for a minimum 3,000 hours, which equates to around 2 years. This is three times longer than the BBA testing approach, giving you greater reassurance when you specify our products.


Giromax testing programme

During the Giromax® product development phase, we continue testing even when we can see that a product is highly durable after 5,000 hours. Using ASTM (American Society for Testing and Materials) compliant testing procedures, we check for a variety of different qualities. This includes user application, adhesion, flexibility, durability and surface abrasion.

Our weather resistance tests go way beyond standard methods. We use a QUV accelerated weather testing cabinet, which is compliant to ISO, ASTM, BSI and various other governing standards. We use the QUV machine to simulate different intensities of UV sun rays to check the coatings resilience to UV damage. The fluorescent lamps can produce UVA, UVB and UVC rays at elevated temperatures; we test continuously for 16,000 hours and longer.

The QUV machine also mimics different wet conditions, such as humidity, water spray and condensation. This allows us to see the effects of rain and dew on our product range. Within a few days or weeks, this equipment can replicate damage caused by several months or years of exposure to the elements.

As well as using the QUC cabinet, we physically test our products by coating panels and leaving these exposed to extreme weather conditions. We can then see how our coatings are affected by storms, snow and ice. This includes full water submersion and checking the effects of pooling water when it freezes, which is useful for our gutter coatings. We also carry out salt spray testing over a 9-month period, which is also important for gutter coatings.

Another type of physical test that mimics the weight and impact of someone dropping a heavy tool or walking onto a roof system is our drop ball testing method. This helps us to develop coatings that withstand roof inspections to check vents and air conditioning units.


BBA approved roof coatings

The Giromax® technical team carry out continuous, extensive and quantifiable testing of our coatings. Our meticulous approach ensures our products are highly effective and robust in a variety of adverse weather conditions. We double-check the results of our QUV cabinet tests by hanging panels outdoors on top of a container or on a panel rack. This ensures that we can develop high-performance roof coatings that always exceed BBA standards.

All Giromax® products are researched, tested, developed and manufactured in the UK. As a result, our products are more resilient to global supply chain trends. We have designed our roof coatings to have a guaranteed lifespan of 15, 20 or 25 years. To obtain our guarantee, the substrate must be prepared correctly and the product applied to the required standard.

Why use solvent-less roof coatings?

Solvents are used in paints and roof coatings due to their ability to improve consistency. They help to dissolve or disperse key components in a formula, reducing clumps or globules on application. A certain level of solvent is needed to ensure a coating can be applied effectively and consistently. But due to innovations in paint technology, market-leading roof coating products have been developed using solvent-less formulas.

At Giromax® we have always produced solvent-less roof coatings. Our technical team continually test and develop formulas to help reduce our environmental impact. Along with solvents, we have also reduced the level of harmful isocyanates in our coatings. Using a solvent-less roof coating is a safer option for contractors and the environment. Our manufacturer is also currently working hard to develop a ‘solvent-free’ roof coating. There are many reasons why we don’t use high solvent formulas in our coatings.


The problem with solvent-based roof coatings

When a coating contains high levels of solvents, this can pose a number of problems. Solvents contain VOCs (volatile organic compounds), which can be harmful to our health and the planet. Read our blog The benefits of using low VOC roof coatings.

Although one harmful solvent, dichloromethane (DCM), has been banned in the UK since 2012, it is still allowed to be used for industrial purposes. This type of solvent is also known as methylene chloride and can be found in a number of coatings. Therefore, it’s important to check the products specified to contractors to ensure they are solvent-less coatings.


We have listed a few common issues to be aware of below:

  • Danger to health
    Solvents give off fumes and, if we breathe in these particles, they can seriously damage our respiratory system, including our lungs. These harmful particles can also be absorbed through our skin. Prolonged skin contact with high solvent-based coatings could cause rashes and burns. Long-term exposure to solvents can lead to serious illnesses such as cancer, organ failure and neurological health issues.
  • More flammable
    Coatings containing high levels of solvents are more flammable, creating a greater fire risk for businesses. This is especially important when there is a lot of dry timber, combustible insulation or other flammable materials onsite at a business premises.
  • Dissolves plastics
    High levels of solvents can damage plastic fittings, causing them to deteriorate and, in some cases, even dissolve. Solvents affect the chemical and thermal properties of plastics, reducing material integrity. This also applies to other materials like bitumen.
  • Toxic to the environment
    Many solvents don’t break down in the soil and can stay present for decades. When solvents leach into nearby waterways, the effect can be devastating to local ecosystems and groundwater aquifers, polluting our natural water sources. Some solvents react to sunlight, which causes them to produce ground-level ozone. This is a major component of pollutive smog, which affects humans, animals and plant life.


Benefits of solvent-less coatings

There are many benefits of using roof coatings containing fewer solvents. The number one reason has to be health and safety above all else. When you specify a solvent-less roof coating, you can be reassured that contractors can carry out their work safely. When it comes to environmental friendliness, using solvent-less coatings ensures your client can adhere to their green agenda. You will be doing your part in helping to protect the planet.

Giromax® roof coatings contain fewer solvents but still offer superior durability and longevity. Our advanced product range has been developed with a next generation polyurethane hybrid solution, which does not emit VOCs. Our roof coatings use revolutionary laminar flake technology, which creates a tough elastic coating to seal and protect the roof. This helps to prevent water penetration, wear and tear, corrosion and superior resistance to UV rays.

Our roof coatings have been designed for easy user application, along with outstanding adhesion properties. With a guaranteed lifespan of 15, 20 or 25 years, your client won’t have to recoat their roof for decades, resulting in easier maintenance programmes.

Giromax® is the original leader in the roof coating market. Our technical team continually test and develop our products with health and safety, user application, durability and the environment in mind.

The benefit of roof coatings with low isocyanates

In recent years, there has been a general reduction of harmful chemicals in roof coatings for the purpose of health and safety, and environmental concerns. Companies are increasingly focused on improving their green agenda. When you choose a coating for a roofing system, using products with lower isocyanates will be safer for your contractors and the planet.

Giromax® is fully committed to health and safety, as well as reducing our environmental impact. As well as having low isocyanates in our roof coatings, our products have always had lower VOCs and solvent-less formulas when compared to our competitors.

High isocyanate levels are dangerous

Isocyanates are a class of chemicals commonly used in the production of various polyurethane-based products, including roof coatings. These chemicals are known for their exceptional adhesive and durable properties, making them suitable for coating formulas.

However, high levels of isocyanates can be potent and pose significant health risks to anyone exposed to them. As semi-volatile organic compounds (VOCs), high isocyanate roof coatings release toxic aerosol mist droplets, which can stay in the air long after application.

Contractors who frequently spray roof coatings containing high levels of isocyanates are at greater risk of exposure and associated health issues. This can lead to respiratory problems, skin irritation, and flu-like shivers. Prolonged exposure to high isocyanate concentrations may also result in severe asthma and serious respiratory diseases. Isocyanates are classed as carcinogens, which can increase the risk of cancer.

Reasons to use low isocyanate coatings

There are many benefits of using roof coatings containing fewer isocyanates, as follows:

  • Improved health and safety

One of the key advantages of low isocyanate roof coatings is the reduced health and safety risk. Contractors and workers have less exposure to harmful fumes and particulates, minimising the risk of respiratory issues and serious health conditions.

  • Environmental friendliness

Low isocyanate roof coatings are more environmentally friendly compared to high isocyanate alternatives. With reduced emissions of semi-volatile organic compounds (VOCs) and hazardous air pollutants (HAPs), they contribute to better air quality and a healthier environment.

  • Long-lasting performance

Roof coatings containing low isocyanates still offer excellent durability and longevity. They form a protective layer that effectively seals the roof, preventing water penetration, corrosion, wear and tear, as well as superior resistance to UV rays.

  • Easier user application

Our low isocyanate roof coatings are formulated to be user-friendly, allowing for easier application. They have excellent adhesion properties, making them suitable for various roofing materials, including metal profiled roof systems and asbestos cement.

Hybrid polyurethane roof coating paint

At Giromax®, we have formulated a range of innovative polyurethane hybrid roof coatings with low isocyanates and fewer VOC emissions. Our single-coat systems benefit contractors in terms of ease of use, resulting in faster and more efficient application. A high standard of application is achieved only when the correct preparation of the substrate has been carried out beforehand. Our roof coatings have a guaranteed lifespan of 15, 20 or 25 years.

When comparing our low isocyanate roof coatings to competitor products, always consider the levels of isocyanates present. Contractors exposed to high levels of isocyanates are putting their health at great risk. By opting for low isocyanate alternatives, contractors can significantly reduce potential health hazards associated with exposure. A roof coating should never compromise workers’ health.

Health and safety should always be a top priority when it comes to the types of roof coatings used for repairs and maintenance. Low isocyanate roof coatings provide a safer alternative and a healthier work environment, while still delivering long-lasting protection and durability for roofing systems. By using our roof coatings, you will be helping to keep your contractors safe, and you will reduce your environmental impact too.

The original cut edge corrosion treatment

The development of Giromax® Edgecoat starts with our late founder, Roy Emmett. An innovative engineer, Roy had a proven background when it came to finding solutions for different problems. Early on in his career, while working for a leading automotive company, Roy invented an efficient new production conveyor.

By the 1980s, Roy had established a pipe-fitting firm, distributing corrosion coatings, and this was where his knowledge of cut edge corrosion began. Roy was introduced to a specialist coating firm with a single yet prestigious customer, British Steel. He subsequently launched this specialist coating to a mass market, developing innovative formulas to treat cut edge steel. As a result, the highly niche, cut edge corrosion market was born. Read more…


The problem with cut edge corrosion

Industrial roofing systems are prone to corrosion at the cut edge of metal profiled sheets. Steel roofing sheets are coated are coated with Plastisol, which provides protection from the damaging effects of weather and UV rays. This durable finish also gives the metal sheets a pleasing aesthetic appearance. At the point where the roof sheets are cut, this can leave the cut edge exposed to air and water. Over time, this oxidises and creates rust, which then weakens the roof integrity.

When a building heats up and cools down, this can cause the metal roofing sheets to expand and contract. As a result, the coating layers around the cut edge can separate slightly away from the metal, resulting in water ingress with capillary action. Damage starts to creep in under the coating, which compromises the metal sheet. At this stage, it’s important to repair the cut edge corrosion to avoid the damage spreading to a greater area.

Corrosion around the lap joints can also cause issues, as the capillary held rainwater can start to penetrate through the protective layers. If left untreated, corrosion at the cut edges can be accelerated, destroying the weather-sealed lap joint and gutter overhang.

When left untreated, cut edge corrosion can be seen in the form of spot corrosion, edge peel, blistering and discoloration. Over time, this could undermine the entire roof’s integrity, leading to serious and costly water leaks. This in turn can cause business disruption if the whole roof needs to be replaced and workers have to be relocated.


Giromax cut edge corrosion treatment

Although strong and robust, metal roofing systems can deteriorate quickly if any cut edge corrosion is left untreated. As the corrosion happens just below the surface coating, it can be hard to spot. It’s important to inspect industrial roofing systems regularly. If cut edge corrosion is detected, however, it can be a simple job to treat.

Giromax® Edgecoat is an innovative, cut edge corrosion treatment. Moisture tolerant, this revolutionary coating system can be applied in damp conditions. The formula treats the top and reverse sides of the cut edges of a metal roofing sheet. Using laminar flake technology and BBA-certified, Giromax® Edgecoat is a cost-effective, weatherproof formula that comes with a 15-year guarantee.

Ideal for cost-effective repairs and dilapidations, Giromax® Edgecoat can be used on metal roofs, cladding and gutters. This cut edge corrosion treatment provides protection and flexibility for external joints. The system is applied using a two-stage process.

The benefits of using low VOC roof coatings

Giromax® has always believed strongly in lessening our impact on the planet. Our products have always been solvent-less with low VOCs, when compared to similar products in the market. But we all have a role to play in reducing our environmental impact, especially in industrial sectors. A proactive approach is key and it’s all in the detail. Choosing products with fewer harmful chemicals helps everyone in the long run.


The danger of VOCs

Nowadays, roof coatings are made from a variety of different chemicals and elements. These can typically range from silicone, polyurethanes, styrene-acrylics, fluoropolymer, butyl resins, silyl terminated polyether (STPE), polyester, polyuria, and more.

Certain volatile organic compounds (VOCs) can be emitted as gases from specific chemicals used in roof coatings. VOCs can cause adverse health effects in the short and long term. Short-term exposure of high levels of VOCs can cause eye, nose and throat irritation, headaches, dizziness, nausea and vomiting. Long-term exposure can lead to serious illnesses such as cancer, liver and kidney damage, and central nervous system damage.

When contractors are using roof-coating products containing high levels of VOCs, they will be exposed to elevated concentrations. It’s worth noting that VOCs can remain in the air long after the roof-coating application is completed. They can also contaminate soil and end up in wastewater flows, causing harm to our wildlife and oceans.

By comparison, our solvent-less products contain fewer VOCs, which makes them much safer for use by contractors and better for the environment. Our products also do not contain silicone, which is a slippery substance and can be dangerous for contractors. It is also prone to bird attacks and more susceptible to mould, dirt and dust. The production of silicone uses hydrocarbons derived from petroleum, which is non-sustainable.


What’s the best coating for a metal roof?

As roof coatings in the industrial sector are used on metal profiled roof systems, it’s important to use a solvent-less product with low VOCs and a good lifespan. By choosing a roof coating with a guaranteed lifespan of 15, 20 or 25 years, you won’t need to repair the roof for well over a decade. That means fewer vehicles and materials being used repeatedly to maintain a roof, reducing your long-term carbon footprint and repair costs.

Your choice of coating will depend on the type of issue you are looking to remedy. Here’s our two top-rated products and how they can be used on metal profiled roof systems:

  • Giromax® Edgecoat – this innovative, BBA-certified, cut edge corrosion coating system treats the cut edges of a metal roof. Moisture tolerant, this formula uses laminar flake technology and can be applied in damp conditions. Giromax® Edgecoat is an affordable, weatherproof solution that will extend the life of your industrial roof for up to 15 years.
  • Giromax® Roofcoat – is a next generation, polyurethane hybrid coating for profiled metal roof sheets, which also uses laminar flake technology. Highly resistant to UV rays and extreme temperatures, this product offers long-term protection against the elements. Similar to Giromax® Edgecoat, this product is also moisture tolerant, so it can be applied in damp conditions, and will extend the life of your roof up to 25 years.

Our range also includes Giromax® Roofcoat for use on asbestos cement roofs, Giromax® Guttercoat for gutter repairs and Giromax® Rooflight Clearcoat for rooflight repairs.

By using Giromax® products you will be helping to reduce your environmental impact, and you will be keeping your contractors safe too. Our low VOC products have always been solvent-less. As the original leader in the commercial roof coatings market, we continually test and develop our products. Our aim is to ensure the quality and safety of our coatings.

Get it right first time: Industrial roof coatings application

It’s how you apply the coating that matters…

Coating issues usually arise when contractors are inexperienced, untrained, or theyre rushing to get the job done. It’s important that the application is carried out steadily and conscientiously with regular inspections to ensure a consistent coating is achieved. Always check the coverage rates for coatings beforehand and quote your project accordingly.

You also need to check the environment and the ambient temperature range to apply our products over 5 and below 35 degrees. If the coating is applied in hot temperatures, the product will cure too quickly and won’t adhere properly. During the summer months, if the ambient temperature is 30 degrees, the temperature of a metal profiled roof could be 50 degrees. Likewise, coatings will also not adhere properly in heavy rain or icy conditions.

Sometimes contractors can feel overwhelmed by the sheer scale of the project at hand. This can result in a hurried approach or even cutting corners, such as the surface not being adequately prepared. We have seen contractors adding extra thinners to coatings, which can severely impair the coating’s effectiveness. You need to be able to spot any issues before they occur, so you can remedy before any coating has been applied.

Remember, once the trigger has been pulled on a paint spraying gun, there won’t be a second chance to get it right. An incorrect application could result in having to go back to the start of the job, which includes preparing the substrate again from scratch. Good preparation is the key to a high-quality coating application.


Preparation for coating applications

Before any coating is applied, the substrate must be prepared to the correct standard. First, you would carry out a thorough clean. This would be followed by either manual or mechanical preparation to the specified standard.

If you are treating cut edge corrosion, for example, you would need to remove any non-adhering rust stains, along with any swarf, dust and debris. Using the Swedish Standard ST3, you would clean the corrosion until you achieve a bright metallic surface. Make sure the surface is not polished; any remaining coating edges must be firmly adhered and well feathered. Use Giromax® Panel Wipes to clean the surface, so it’s free from grease or oil.

Plastisolcoated roof systems can pose different challenges. We often come across heavily delaminated roofs that need intensive mechanical and manual cleaning. Typically contractors will want to ensure the finished job has the smallest amount of edge curl.

When high-pressure power jets (3,000 psi) have been used to clean away old coatings from roof sheets, islands of the original plastisol can remain. These areas need to be feathered out to lessen the risk of edge curl after the new coating has been applied. Otherwise, expensive lead edge repairs will need to be carried out.

Equality, diversity and inclusion in the surveying industry

Equal gender representation

Over the years, the surveying industry has struggled when it comes to inequality, exclusion  and a lack of diversity. According to a recent article published by the Royal Institute of Chartered Surveyors (RICS), it’s thought that women make up only 10% of the workforce in the construction industry. Those who do work in this sector are still facing a gender pay gap and various barriers, resulting in many women still not being considered for promotion.

Unconscious biases around women are common, such as being more susceptible to injury, not being suited to workwear or able to use equipment. There are still considerably fewer female surveyors in the industry, as well as less representation across different ethnicities and the LGBTQIA+ community. There are also a large number of companies that do not have any equality, diversity, and inclusion (EDI) policies in place.


Inclusive attitudes towards diversity

Diversity covers a range of characteristics, including (but not limited to) gender, race, ethnicity, age, disability, and socio-economic background. Many companies are actively seeking to attract and retain talent from diverse backgrounds. Targeted recruitment helps, but ultimately, encouraging underrepresented groups to join the industry should start in educational settings. Young people need to feel inspired to work as surveyors.

From an inclusion perspective, there has been an increase in the number of surveyors from different religious backgrounds, and more awareness of their needs. RICS recently highlighted the importance of encouraging inclusivity for Muslim professionals who wanted to celebrate Ramadan. There has been a rise in construction sites offering spaces for Muslims to pray, for example, and flexibility over the fasting element of Ramadan.


The importance of equality, diversity and inclusion

Embracing equality, diversity, and inclusion (EDI) in the surveying industry brings a multitude of benefits. Firstly, it fosters innovation and creativity. Diverse teams bring together different perspectives, ideas and experiences, leading to more innovative solutions and approaches to problem-solving. By including a broader range of people, the industry can draw from a greater pool of expertise.

Secondly, an inclusive surveying industry helps to build trust and confidence among clients and the wider community. Many companies have EDI policies, actively encouraging representation across internal areas of their business, as well as suppliers and contractors. When people see themselves represented in a profession, they are more likely to engage and collaborate, which in turn encourages more people to join the industry.

Equal pay and opportunities for career advancement are also crucial when it comes to ensuring fairness within the surveying industry. Transparent pay scales and regular reviews could help to address any existing gender or ethnic pay gaps. Mentoring programmes and professional development initiatives could help underrepresented groups access more career progression opportunities.


Promoting equality, diversity and inclusion in surveying

Promoting equality means creating an environment where every individual, regardless of their background, has an equal opportunity to thrive. In the surveying industry, this could be achieved by implementing fair and transparent recruitment processes, focusing on skills and with an awareness of unconscious biases. Equality, diversity and inclusion (EDI) policies work better when they have measurable goals and targets to track progress.

Creating an inclusive workplace culture is equally important. Inclusion goes way beyond just representation; it’s about creating an environment where everybody feels welcome. Encouraging open, respectful dialogue with an appreciation for diverse perspectives will help people to feel valued. Assess policies and practices to identify and remove any barriers that could be affecting underrepresented employees.

Address unconscious biases, promote flexible working arrangements, and provide training on diversity and inclusion topics for all staff members. By actively involving employees from diverse backgrounds in decision-making processes and leadership roles, the surveying industry can become more reflective of society.

Like any other sector, the surveying industry has a responsibility to champion equality, diversity, and inclusion. By embracing these principles, the industry can unlock new opportunities for growth, innovation, and collaboration. An inclusive workplace culture will enable surveying firms to become more representative and respected. It is a collective effort, but together, let’s create a surveying industry that reflects the rich diversity of our society.

Giromax believes strongly in promoting equality, diversity and inclusion across the surveying and construction industry. Our team includes women in senior and technical roles, and we actively encourage everyone to take part in professional development and training.

Sustainable roof coatings for a low carbon strategy

Green agendas attract funding

Climate change is a hot topic, and companies worldwide are seeking to improve their green agenda. Achieving a low-carbon status can be very challenging for certain industry sectors, but small measures can go a long way. Using more environmentally friendly products for maintaining business premises, such as roof coatings, is a viable and positive contribution.

As well as helping the planet, going green can have some financial benefits too. Businesses can tap into a wide range of sustainability and green grants to fund low-carbon innovation projects or to increase green spaces. Not only does this help to improve the environment, but it also improves the reputation of the business. Customers, suppliers and investors are increasingly seeking green credentials for companies.

It’s not just about production, it’s about protection

With any type of roof coating, there is a manufacturing process. We use less solvents, low isocyanates and low heavy metal content (often found in 2-pack PU coatings) in our products. Our solvent-less roof coatings have low VOCs, which makes them safer for the planet and the contractors who apply our products. This results in our manufacturing processes also being less harmful to people and the environment.

But it’s not just about production methods and chemical components, it’s also about the long-term protection provided by our roof coatings. This means you won’t have to use extra products to recoat the roof, saving on costs and any associated fuel used by contractors.

Our Giromax Roofcoat, for example, is a protective, industrial roof coating that can be applied using a single coat. It’s been designed to withstand significant UV exposure, snow, ice and wet weather conditions for up to 25 years. It’s also moisture tolerant, so it can be applied during damp conditions, maximising the time your contractors need to be onsite.

If you would like to know more about the environmental benefits of using Giromax products, speak to our Technical Services Managers. If you need technical guidance, please call 01455 558969.

Simply the best! How we built our great reputation

The facts speak for themselves…

It’s already common knowledge, is it? Or is it a closely guarded secret that our competitors don’t want you to know? that our coatings are of a higher quality with better user application than other roof coatings on the market. They’re also more eco-friendly, as they contain 30% less solvents on average, which mean they contribute to reducing scope 3 carbon emissions. A tiny percentage of jobs we supply are subject to remedial action, and these are down to poor application of the coating. That’s why we are undertaking a comprehensive review with our contractors and providing free training and education to ensure right first time application.

Getting the job right first-time round is important to us,  below are some stats which show how much coating we have actually provided (free of charge) to correct jobs that required remedial work:


  • 2,415 litres of the Giromax Guttercoat system were provided free of charge, out of 84,413 litres = That’s just 2.86% of total product sold that have been used on remedials.
  • 2,355 litres of Giromax Roofcoat system were provided free of charge, out of 240,016 litres = That’s even less at just 0.98% of total product sold that have been used on remedials.
  • 678 litres of Giromax Edgecoat system were provided free of charge, out of 28,437 litres = again just  2.38% of total product sold have been used on remedials.


High standards

We’re not your average roof coating company. Our current team are highly trained and do not give out guarantees unless the job has been completed to the required standard. One of the benefits of our products is the fact you only need to apply a single coat. To meet our high standards, and receive our guarantee your contractors must achieve the following:

  • Correct preparation of the substrate.
  • Skilled application of the coating.
  • Applied within the correct climate range.

Our list of trusted contractors means we can offer the reassurance needed when it comes to a project being completed on time and on budget. Our Technical Services Managers will regularly complete onsite visits to ensure every stage of the project has been carried out correctly, offering advice and guidance along the way if needed. If the climate isn’t right or the substrate hasn’t been prepared correctly, they will highlight this and let the contractor know that the coating cannot be applied, so as to avoid any risk of remedial action being needed.


Superior products

Many of our products have been developed with cutting-edge technology and as a result of our extensive R&D over the years, are more eco-friendly than any competing product.

  • Our products use Laminar flake technology – creating extra hardness and strength where it’s needed, including long-term chemical resistance. Due to their neutral mass, laminar flake coatings are ideal for large areas, and they won’t cause structural issues.
  • They are Moisture tolerant – most of our products can be applied in damp conditions, increasing the number of days contractors can work on
  • More eco-friendly than any other product on the market – on average, our coatings contain 30% less solvent than competitor brands. Our coatings also have low isocyanates and low heavy metal content, these are often found in 2-pack PU coating products, and can be detrimental to workers’ health.
  • They are Silicone free – unlike competitors, we don’t use silicone in our products, which – when applied, means that the coating is prone to dust, dirt, mould and bird attack. Our coatings contain 87% paint compared to the solid content of a silicone-based paint which averages 60%.


In-house technical team

Giromax has a dedicated team of technical experts working continuously on testing and developing our product range. Our aim is to improve user application, adhesion, durability, surface abrasion, weather resistance and flexibility.

Our technical team use a QUV accelerated weather testing cabinet, and they also physically test coated panels outdoors in a real-world environments. A QUV machine is an approved testing facility compliant to ISO, ASTM, BSI and numerous other governing standards.

Giromax coatings are tested for a minimum of 3,000 hours (2 years) when compared to the standard 1,000 hours of BBA (British Board of Agreement) testing. We also use ASTM (American Society for Testing and Materials) compliant testing procedures to check for a number of qualities in our coatings. This includes user application, adhesion, durability, surface abrasion, weather resistance and flexibility.


Onsite Technical Services Managers

Our Technical Services Managers carry out regular site visits to check on the preparation and application of our coatings. Having worked on large-scale projects across the UK, their roof coating expertise is second to none.

We also offer onsite spray training for our customers, carried out by a fully qualified sprayer. Highly experienced in the application of our products, our Application Consultant has 40 years of expertise and decades of knowledge using our Giromax® coatings. They are available to provide training on the correct way of applying the Giromax® product range.

Does installing solar panels damage your industrial roof?

We recently surveyed a rooftop for a plastics printing company. This business was using approximately 3 million kw of energy each year and needed to reduce the cost of electricity. They want to install solar panels on their industrial roof, which offers a 25% reduction ontheir energy bill. Prior to the solar panel installation, work has started on preparing the sheets and the application of Giromax Roofcoat to protect their roof system.

Following the installation, we will inspect the roof again to check if the drilling process for thefixings has damaged the roof and exposed cut edges. We will then advise on whether anyrecoating and remedial work is needed to ensure the coating guarantee isn’t voided. There are various ways that an industrial roof can be damaged by a solar panel installation.

5 ways solar panels can damage industrial roofs

While solar panels provide excellent energy and cost savings, they can cause damage to industrial roofs if they are not installed properly. In some cases, the roof might not besuitable for solar panel installation. We look at a few ways solar panels can damage industrial roofs.

1. Weight and pressure

Solar panels can place a significant amount of weight on a roof. This weight can cause stress on older roof structures, which can lead to cracks and other forms of damage. Additionally, the pressure from the solar panels could cause weaker roofs to bow or warp, causing damage over time. Therefore, it’s important to check the roof integrity of older buildings, which should be covered in your roof survey.

2. Wind damage

Solar panels can also be damaged by strong winds. If the panels are not securely attached to the roof, they can lift off during high winds. This can cause damage not only to the panels but also to the roof surface itself. Always check your industrial roof after severe weather. Giromax roof coatings have been developed to withstand extreme weather conditions, including heavy rain, snow, ice and UV rays.

3. Water damage

As solar panel installations require penetration of the roof to secure the panels with fixings, this can create entry points for water ingress. The fixings should be watertight but if they are faulty or not affixed correctly, water could seep into the roof and cause a leak. Leaking water will lead to damage inside the building, including mould. Make sure the fixings seal correctly and the installation hasn’t damaged the surface.

4. Cut edge corrosion

As the installation involves penetrations through the surface, the cut edges of the metal sheeting can become exposed, which could lead to corrosion. The sheet lapsand lap joints need to be encapsulated with a suitable cut edge corrosion coating,such as Giromax Edgecoat. This market-leading cut edge corrosion repair system ismoisture tolerant and comes with a 15-year guarantee.

5. Maintenance issues

Installing solar panels on an industrial roof can create maintenance issues. If the panels are not installed intelligently, they can obstruct access to air conditioning units, vents and skylights. This can make it difficult for workers to carry out routine maintenance tasks and repairs. Additionally, if the panels are not cleaned regularly, they can become dirty, which will reduce the overall efficiency of the solar system.

Preparing an industrial roof for solar panels

Solar panels undoubtedly offer excellent energy and cost-saving benefits to businesses, as well as helping to tackle climate change. To avoid any issues, we always recommend working with a professional solar panel installer. If you’re a surveyor, your assessment of a roof’s suitability for solar panel installation will also be a useful factor in your client’s decision-making process. Your guidance on the weight limits of the roof could be crucial.

Before the installation, we recommend a full inspection of the roof surface. Our team will check for any signs of cut edge corrosion, looking at the sheet overlaps. We’ll also look forany corrosion on the heads of fixings and inspect any skylights and vents. We will then advise on whether the roof needs a recoat or any treatments to ensure the roof integrity.

After the solar panels are installed, we will reinspect the roof to see if there’s any damage to the coatings and whether any remedial work is required.

The Giromax team include Technical Services Managers, who provide expert advice to contractors. If you need technical guidance on our products, please call 01455 558969.

Technical Talk: How to spray paint and specialist coatings

About Tony

Tony has worked for Giromax since 2023, and he’s had a varied career over the past four decades. Tony had a brief spell in the Merchant Navy, followed by an apprenticeship with a painter and decorator. Their work focused on painting factories and steelwork, where Tony learned specialist skills in paint spraying.

After his apprenticeship, he went on to work with a high-end painting and decorating company. During this time in the 80s, Tony worked on industrial units, offices, shops and hotels, including the Savoy and the Dorchester.

At night-time, he would work on the supermarkets. When Key Markets were bought out by the Somerfield chain, Tony worked on the branding changeover. He also worked for the Berni Inn chain, when they added ensuites to all their rooms. His claim to fame is gold-leafing the mouldings around Big Ben.

Tony became well-known in the industry for his paint-spraying knowledge and high-end decorating expertise. In 1988, he started his own business working on dilapidations, including shops, offices and industrial units.

Tony and his two sons worked on industrial roof coatings and internal hygiene coatings. He sprayed a hygiene coating to the back of house kitchen walls of Gordon Ramsay’s Grill restaurant. Unfortunately, during this time, one of his sons fell through an asbestos roof. Consequently, Tony went on to develop a serious interest in coatings.

In 2001, Tony was introduced to Giromax coatings and became a preferred contractor, applying the Giromax Girosil range from 2018. He joined our team as a consultant on 1 March 2023. Three of Tony’s jobs using products from the Giromax range were featured in building magazines. Let’s hear what Tony has to say about best practice for paint spraying and health and safety.


Best practice for paint spraying

Tony works alongside our Technical Services Managers. As our Application Consultant, he attends onsite to ensure contractors complete the job to the required standard for our guarantees. If required, Tony will create a sample area as a reference to guide contractors and the site manager, so they can reflect this standard across the entire roof.

Take your time. Be conscientious. Look at what you’re doing, and don’t worry about the metreage because you have to do it properly the first time. You wont get a second time. Once you pull that trigger, whatever you’re spraying will be applied to the roof.”

Problems occur when contractors use people who either do not want to do the work or lack the skills to be able to spray the coatings to a high standard. Due to the vast size of industrial roofs, it’s too easy to become impatient. Good preparation is key. Contractors must prepare the substrate to the correct standards. Some contractors push the boundaries of a project to the point where the coverage isn’t adequate to obtain our Giromax guarantee.


Competency for paint sprayers

Tony’s qualifications, expertise and in-depth knowledge of the Giromax product range not only enhances our customer service but ensures the correct application of our coatings.Instead of offering a training centre, Tony delivers high-quality onsite training to contractors as required, which includes full assessment and the giving out of competency cards.

Tony has all the correct ancillaries and equipment available to provide expert paintspray training. He can immediately spot issues before they occur, for example, when contractors mistakenly add extra thinners to coatings. Tony will advise on the correct application, preparation and equipment needed to achieve a high standard of coating. This includes checking the environment and temperatures are within range to apply our products.


Paint spraying health and safety

When it comes to paint spraying, safety is a subject close to Tonys heart. When his son fell through an asbestos roof, he survived the fall. Since then, Tony has made health and safety a top priority in his practice. He has taken all available qualifications to manage a site, which is an added benefit for our contractors and surveyors.

Tony’s site manager qualifications include SMSTS (Site Manager’s Certificate), which involved a 5-day course, and he holds a black CSCS card. He also has IOSH qualifications covering lifting, moving at height and asbestos.

The most important thing for me is to pass on my 40 years of knowledge to improve the application of coatings, but above all, to keep contractors safe.

At Giromax, we’re very lucky to have Tony as our Application Consultant and to support our clients. Alongside our Technical Services Managers, Tony delivers expert training and advice to contractors. His onsite presence ensures your project is delivered without issues.

How changing market conditions can affect your business

Market challenges range from chemical price rises and supply chain pressures to shortages and delays. These have all had a significant impact on the industry and its competitiveness. Understanding the challenges faced by the industry can help companies prepare and adapt to overcome them, as well as remaining competitive in the marketplace.


The effect of market challenges

One of the biggest challenges faced by the chemical industry has been the rising cost of raw materials. Over the past decade, the cost of key chemicals used in the production of industrial paint and roof coatings has increased significantly. For example, the cost of titanium dioxide, a common white pigment used in paint, has more than doubled in the past ten years due to increased demand, reduced supply, and environmental regulations.

The rise in chemical prices has a direct impact on the cost of production for companies and can make it difficult for them to remain competitive in the marketplace. In addition to chemical price rises, UK manufacturers that rely on the supply of chemicals from overseas have also faced significant supply chain pressures.


COVID and the chemical industry

The COVID-19 pandemic disrupted global trade and created bottlenecks in the supply chain. This led to shortages of key chemicals used in the production of industrial paint and roof coatings. For several months, these shortages caused delays in production and the supply chain was significantly affected. For some, this increased costs, making it more difficult for companies to meet customer demands and remain competitive in the marketplace.


UK chemical industry

For many years, the UK chemical industry has faced challenges by rising competition from overseas producers. With the rise of China as a major chemical producer, some chemical companies face increased competition from low-cost overseas suppliers. This competition is driving down prices, making it more difficult for UK-based companies to compete on price alone.


Economic pressures

Economic changes in the marketplace are also having a significant impact on the UK chemical industry. According to the Chemistry Industry Association, the dramatic rise in inflation is “eating into margins and consumer prices”. Energy costs, raw material costs and shortages, and labour costs have all been cited as the four biggest pressures on UK manufacturers at the current time.


Environmental changes

Manufactures are also facing increased pressure from environmental regulations. Governments around the world are becoming more focused on reducing the environmental impact of industrial activities, and the chemical industry is no exception. Companies are being required to adopt more sustainable practices and reduce their use of hazardous chemicals. This can result in increased costs and less competition in the marketplace.

In conclusion, the UK roof coating industry needs to focus on innovation and efficiencies to overcome challenging market conditions. This is essential if they want to remain competitive in the marketplace. Companies can only succeed by focusing on the development of new coating technologies and by maintaining strong relationships with customers and partners.

At Giromax, we carry out continuous development and rigorous testing of all our roof coatings, cut edge corrosion treatment and gutter repair products. We manufacturer our roof coatings in the UK, making us much more resilient to global trends. We also have a trusted list of approved contractors, which we recommend to surveyors using our products.

We have always differentiated ourselves from our competitors. Giromax not only started the UK coatings market, but we have evolved to meet the needs of a changing marketplace. Last year, despite increased market competition, we offered a 20% price decrease, and yet we still lead the roof coatings market. This year, we have expanded our Technical Services Managers team, who are on hand to advise contractors and surveyors.

How climate change is affecting the roofing industry

Weather extremes

Climate change is already here. Even in the UK, we are seeing unprecedented and volatile weather conditions. As a result, our roofing systems are becoming increasingly vulnerable to damage from extreme heat, heavy rainfall and high winds.

Although many roof coatings have been developed to withstand such conditions, including the Giromax range, it’s the application that matters. For our own product range, the ideal temperature to apply our coatings is between 5 and 35 degrees. We do not recommend applying our products above or below this temperature range, as this could lead to issues and possible remedial work.

In extreme heatwaves, metal profiled roofing is likely to be much hotter than the recorded day temperature. If it becomes too hot, the roof coating might not stick to the substrate or thicken properly. It’s worth noting that coatings cure faster in warm temperatures, which means contractors may need to rethink their working day. In the heatwave of summer 2022, contractors were forced to start work early to avoid the extreme daytime temperatures.

Although we haven’t yet had extreme snow this year in the form of the “Beast from the East”, record-breaking, freezing temperatures were recently recorded in the USA and Canada. The North American continent experienced a “bomb cyclone”. In sub-zero temperatures, roof coatings won’t stick to the roof substrate. If ice gets trapped between the poorly applied coating and the substrate, problems can arise later down the line.

The same problem applies to heavy rainfall. Extreme, stormy weather is on the increase, which could delay contractors when it comes to finishing a roof-coating project. Rain showers will affect the roof coating, preventing it from sticking to the substrate.


Roof coating products for damp conditions

Giromax has specific products that can be applied in damp conditions, although we do not advise applying during a rain shower. Giromax® Edgecoat and Giromax® Roofcoat can both be applied in damp conditions. Designed to provide durable and long-lasting protection, these coatings are highly effective solutions for metal profile roofing systems.

Our roof coatings are made from high-quality materials, including elastomeric polymers, providing a flexible and durable barrier against water and moisture. The coatings are also resistant to UV rays and weathering and have been designed to endure harsh weather conditions. As a business, we have ongoing product testing and development to ensure continual improvements can be made to the user application of our products.

Climate change is a global issue, and the roofing industry has a big role to play in reducing its impact. By using more sustainable materials and manufacturing processes, we can all play our part in helping to reduce the carbon footprint of the roofing industry. As a roof coatings company, we also want to contribute to a more sustainable future for our planet.

At Giromax, we have always factored in environmental concerns when it comes to the development of our product range. Our solvent-less roof coatings have low VOCs, making them safer for the environment and for the contractors who use our products. If you are interested in finding out about our coating products, we will be releasing videos on our website in the months ahead.
