Cut Edge Corrosion

Corrosion generally begins at the cut edges of a metal sheet on your building, and will appear to be peeling. It occurs through normal weathering, usually at overlaps and eaves. If neglegted, cut edge corrosion will develop away from the cut edge and destroy the weather-sealed lap joint and gutter overhang. Early detection and effective treatment however, will prevent costly future sheet replacement.

Catching the damage early

Cut edge corrosion is a progressive problem. If neglected, it will progress and eventually destroy the weather-sealed lap joint and gutter overhang. It further eats into the metal – and the problem becomes more than cosmetic. Serious cases can cause leaks in your business premises, as well as compromising the building’s integrity. Early detection and treatment of the edge peel will prevent a costly roof sheet replacement which heavily reduces the roofing costs and disruption at site and to your business.

What are the root causes of cut edge corrosion?

Cut edge corrosion usually starts as edge peel at the cut edges of a metal profiled roof sheet. The process starts through normal weathering of sheet overlaps and eaves, which then accelerates through capillary water held in the lap. The cut edges are vulnerable to weathering, oxidation and pollutants because they are left exposed and do not have a protective plastic coating that the rest of the metal or aluminium cladding has. The climate in South Wales often results in vulnerable metals being exposed to poor weather conditions and as a result, rapid corrosion deterioration.

Cut edge corrosion treatments

Here at Charles Perrett Maintenance, we can assess and evaluate your commercial cladding if you think you have corrosion. We carry out a thorough assessment before discussing treatment. If the problem is severe we’ll even carry out the commercial roof repair. For more information, please contact us today!
