Cut edge corrosion is a form of deterioration affecting factory‑coated profiled metal roofing and cladding sheets. It occurs where the protective coating has been cut, trimmed, or where overlaps exist, leaving the raw metal edges exposed. Over time, coating delamination, weather exposure, rainwater, and capillary action cause the exposed edges to rust, peel back, and ultimately perforate if left untreated.

Call us on 0113 873 1220At Roofing Supplies, we are approved contractors for systems including Seamsil®, Giromax®, and others. Here's how we address cut edge corrosion:
| Product / System | Key Features |
|---|---|
| Seamsil® System | Silicone‑based remedial treatment for cut edges and overlaps. Resistant to UV, weather, industrial pollutants. Provides a flexible coating, strong adhesion to substrate – 5 years (manufacturer's guarantee) |
| Giromax | Hybrid polyurethane / laminar flake technology, moisture tolerant, treats both faces, flexible. BBA certified |
We conduct a site survey to identify and map all cut edges, overlaps, areas showing coating peel, rust, or structural weakening.
Clean the affected areas thoroughly — remove loose coating, oxidation, rust scale.
Apply a corrosion‑inhibiting base coat specially designed for cut edge treatment systems. Ensures adhesion and stops further rusting. Apply the sealant to encapsulate the edge, overlap joints and exposed metal. Colour matching available.
Once cured, final inspection is carried out to ensure watertight finish, durability, and aesthetic condition. We issue guarantee documentation for the system used. Maintenance advice provided.
A: As soon as signs of coating peel, rust at edges or lap joints appear. Early treatment is far cheaper and less disruptive.
A: It depends on the system and condition. Many suppliers require removal of old failed layers before applying certain high performance systems. Overcoating may hide deeper corrosion.
A: Usually depends on extent and access, but isolated repairs can often be done quickly, while large scale operations may need planned scheduling.
A: Many topcoats come in colour ranges allowing blending. For best aesthetic result, masking and proper finishing are used.
