Cut Edge Corrosion Treatment
Stop rust spreading across your roof sheets. Our specialist treatment seals exposed edges, prevents leaks, and extends your roof's life by 15-20 years.
What is Cut Edge Corrosion?
When metal roof sheets are cut to size during installation, the factory-applied coating is removed from the cut edges. These unprotected edges are exposed to rain, moisture, and air — causing rust to form and spread across the sheet.
Left untreated, cut edge corrosion leads to leaks, structural damage, and eventually the need for a full roof replacement. It's one of the most common issues on commercial and industrial buildings over 10 years old.
The good news: if caught early, cut edge corrosion can be treated at a fraction of the cost of re-roofing — typically saving 70-80%.
Signs You Need Treatment
Rust staining on roof sheets
Orange/brown streaks running down from the overlaps or edges of your roof panels.
Flaking or bubbling paint
The factory coating is lifting away from the metal, exposing bare steel underneath.
Water ingress or damp patches
Leaks appearing inside the building, especially near the edges or overlaps of roof sheets.
Visible rust at sheet overlaps
Corrosion visible at the points where roof sheets overlap — the most vulnerable area.
Building is 10+ years old
Most metal roofs start showing cut edge corrosion after 10-15 years, even with good coatings.
