Commercial Metal Roof Repair

It’s natural for profiled metal roofs on commercial units to experience corrosion to the sheet edges after long-term exposure to the elements. The right approach to commercial metal roof repair will help to minimise damage and health and safety concerns. With our help, you can avoid costly roof sheet replacements by repairing and restoring the condition of the current roof with an innovative coating solution.

Problem: Cut Edge Corrosion

When profiled metal sheets are cut to fit the size of a commercial building, its manufacturer-fitted protective layers are left exposed to the elements. Unfortunately, UV, weathering and standing water can catalyse the natural process of corrosion in these exposed areas, causing visible damage and discoloration as well as loosened joints and leaks.

When signs of cut edge corrosion begin to show, including fading, delamination and blistering, the advice is often to replace the profiled metal roof sheets. However, this is not without significant cost, time and disruption to work being conducted in, on or around the rest of the building.

Contractor Services - common issues and what to expect

Common Issues:

  • UV exposure makes paint hard and brittle limiting its ability to expand and contract with the substrate, affecting adhesion & causing it to delaminate
  • Moisture laying on the surface can penetrate a coating causing discolouration, lifting and corrosion on a steel substrate
  • Important pigments added for colour, UV stability etc. are lost through chalking, a natural self-cleaning process where paint literally wears away
  • Profiled metal roof sheet replacement comes at a large cost and is disruptive to the project or regular business activities

  • Metal roof repairs can help to prolong the lifespan of a commercial roof by decades.
  • Regular roof maintenance ensures any areas of corrosion are spotted quickly before the integrity of the metal sheet is affected.
  • Steel roof repairs and metal roof refurbishment will help you avoid a full roof replacement, which is costly and disruptive.
