What is Cut Edge Corrosion?
Cut edge corrosion is a common but serious issue affecting plastisol-coated metal roof sheets. It occurs at the edges where the sheets were cut to size or where they overlap. When these edges are exposed to the elements, the factory coating begins to peel away from the metal substrate, allowing moisture to seep in.
If left untreated, the metal begins to rust and “eat back” into the sheet. This eventually destroys the structural integrity of the roof, leading to leaks, weakened fixings, and—if ignored for too long—the need for a total roof replacement. Johnrose Roofing provides specialized treatment systems designed to halt this decay and restore your roof’s lifespan.

Why Act Now?
Corrosion is a progressive problem. What starts as a small line of rust at the lap joints can quickly turn into a major liability.
Prevent Total Replacement: Treating the edges is a fraction of the cost of replacing entire metal sheets.
Stop Water Ingress: Capillary action can “wick” water between overlapping sheets, causing leaks that are difficult to trace.
Maintain Property Value: A well-maintained metal roof is a key asset for any commercial or industrial building.
Insurance & Warranty Compliance: Many building insurers and original manufacturers require active maintenance of cut edges to keep policies and warranties valid.
