Technical Talk: Preparation is the Key for Roof Coatings

About Richard

Richard has worked for Giromax for over 5 years and has a wealth of technical knowledge relating to the preparation and application of our products. Before working for Giromax, Richard worked as a landscape gardener, he was in the RAF and the police force, based on the Tactical firearms unit. He believes these experiences have provided him with essential communication skills, helping him to interact with a range of different people. Read more…

Liaising with surveyors, contractors, landlords and building owners, Richard provides written reports and verbal advice to ensure the correct preparation and application of our roof coatings. He oversees the Technical Services Managers, who have designated regions across the UK. Richard also has his own region, which starts from Nottinghamshire and covers the north, including Scotland and Ireland. He makes regular site trips to inspect roofing works.

Let’s hear what Richard has to say about the challenges he often faces in his daily work, along with some of the varied projects he has worked on over the years…

Poor preparation leads to problems

Correct preparation and application of our coatings is the key to ensuring a roofing project meets our high standards, which then allows us to sign off our guarantee. We can recommend contractors, who we trust to follow our preparation and application guidelines. The problems can start when an inexperienced contractor has got the job and they don’t follow the guidance. This can lead to costly remedial works needing to be done.

A typical example of poor preparation of a metal profile roof usually consists of the incorrect pressure washer being used to remove old coatings. As a minimum, we recommend a 3,000-psi pressure washer with a turbo head. In some cases, 4,000 psi might be required. Unless the correct preparatory work is carried out, the application process can be hindered. We won’t confirm any roof is ready for application until the area has been correctly prepared.

Roofing projects

A recent project, which is drawing to a close, has involved inspections and roof coating advice for a large organisation with multiple depots. The area of the metal profile roof is around 15 – 16,000 square metres. The contractor had issues with adequately preparing the surface for a coating application. The incorrect pressure washer was being used, which meant the old coatings were not being removed to a secure edge and was still flaking from the metal roof sheet. The contractor’s had to prepare the roof to the correct standard.

We regularly work with the NSS Group on roofing projects, providing assistance, as required. We recently advised on a roof area measuring several hundred metres for a company based in Washington. This job required a wide variety of works, from cut-edge corrosion to recoating a skylight, valley gutters and small areas of roofing. At present, we are assisting with a large cut-edge corrosion project on a building in Sunderland.

But not all of our jobs are large-scale; many are much smaller and can be very varied in terms of sites. Nowadays, metal profile roofing is not only used on industrial buildings. Over the years, we have advised on projects for a wide range of buildings, from convention centres to football stadiums and stands, as well as scout huts.

Advising on roofing projects

The role of a Technical Services Manager is very varied, and our team are multiskilled. Along with providing recommendations, Richard also reviews every remedial job that comes in. Diplomacy and clear communication are important to ensure contractors follow the correct guidelines to avoid costly mistakes for the main contractor’s client in the long run. We provide advice at the start of a job and at regular intervals throughout, as required.

Every single job will involve a certain level of interaction from us with the contractor or surveyor. We attend most jobs in person, and we always attend if requested.

It’s often important to ensure a pre-sign off, which we recommend before the scaffolding comes down, so we can inspect the roof up close. Small misses can lead to large problems in the long run, and careful inspections are essential to obtaining our guarantee. We can provide technical guidance in a variety of forms, including factsheets and videos.

When it comes to roof coatings, we’re the original leader in our market. Our product range is continuously being developed and improved. If you need technical advice on preparation, application or remedial works, please speak to the Giromax team or call 01455 558969.

The Giromax Story – Part 2

Roy’s grit and ingenuity to form multiple successful businesses is something he demonstrated at every turn. Over 25 years, he led the business to become the industry leader in the refurbishment and protection of commercial roofing and cladding. Through Roy’s dedication, he created a company that values the quality of its products, as much as the team-focused performance they provide. Today, Giromax has become synonymous with delivering excellence and reliability.

Developing a team of industry experts

Over the years, Roy developed a core team of experts, including some very well-known faces. Some of these individuals have their own (slightly different) take on the industry and products when it comes to addressing the challenges of cut edge corrosion.

Many of those Roy employed have remained with the business, benefitting from his mentoring and the expert knowledge he invested in developing. Whether as competitors or as loyal staff, there can be no doubt that Giromax has benefitted the entire cut edge corrosion market. What began as a small, family-orientated business has increased awareness of the ability to effectively refurbish aged steel roofing.

Developing innovative formulations

The cut edge corrosion market has also benefitted from Giromax’s investment in the development of innovative new formulations. The application of products has become easier and more cost effective; formulations which others try and yet fail to replicate.

Giromax was the first to develop the new generation of advanced hybrid polymer products, moving away from old silicone-based products. We are the brand trusted by both the specifiers of dilapidation and refurbishment projects, as well as contractors on the job.


Giromax has created and delivered pioneering products, which are unrivalled in the industry, supported by the development of exceptional back-office support. This ensures projects run smoothly from the initial site survey with our dedicated team of Technical Field Managers, through to specification, manufacture, installation and quality control.

Cut edge corrosion of a metal roof

As markets go, the treatment of pitched metal roofs on industrial buildings is relatively niche. Modern metal roofing has become a familiar sight in this country, thanks to its strength, durability, weather resistance and ability to be easily repaired and refurbished. Roofing made from profiled metal sheets can withstand extreme temperatures and resist all types of weather conditions.

Over time, however, the cut edges are exposed to oxygen, which causes them to deteriorate and corrode. Once rust has set in, the integrity of the cladding is very quickly compromised, so it’s essential to undertake regular checks. Even if the cut edges are protected this can wash away over time, depending on the quality of the coating used. The edge can become exposed and susceptible to capillary action, causing underside corrosion. If left unchecked, this corrosion can lead to a costly roof replacement.

Maintaining a metal roof

Regular assessments are an essential part of an effective metal roofing maintenance programme. When checking a metal roof on an older commercial property, it’s important to use the right type of products to carry out any repairs, especially when it comes to dealing with cut edge corrosion.

The Giromax range of coating products are specifically designed for metal profiled roofs. The products we offer address both the top and reverse side of the cut edge. Easy to apply, laminar flake technology seals and bonds with the corrosion.

Cut Edge Corrosion

Evidence-backed guarantees

Our cut edge corrosion treatment has up to a 25-year guarantee. Only a business with a historical track record like Giromax can guarantee their products with any degree of confidence. This can be evidenced through our contractor relationships, longevity, and continuous testing and certification. What we can guarantee, others are still trying to prove.

Roy left the business in great hands. We have a strong leadership team with complimentary skills and a bias for action. We continue to focus on developing our staff and expertise, as well as our products and processes. Giromax is in a strong position to maintain roofs for another 25 years, guaranteeing our products, while others fall by the wayside.

In the next part of our series, we will consider the market today and where we believe the future lies for Giromax and the cut edge corrosion market.
