What is cut edge corrosion?
Cut Edge Corrosion is the term given to corrosion that develops at the cut edges of a steel roof sheet. It can develop from poorly coated machined edges of the metal sheets, or by breakdown of the original lap sealants, allowing water to be retained between the roof sheets. As the steel begins to corrode, the original coating peels off and water is further retained between the roof sheets, exacerbating the corrosion further.
If unchecked, cut edge corrosion can progress to become a serious problem affecting both the weatherproofing and structural integrity of the roof. By addressing this issue early with application of a dedicated metal protection product such as Rooflock Cut Edge Corrosion System, potentially costly and disruptive remedial action can be avoided.
