Cut Edge Corrosion: Protect Your Roof’s Weakest Point (and Save Money)
At Storm Coatings, we understand the importance of a healthy roof. But even the most robust metal roof cladding can succumb to a silent threat: cut edge corrosion.
What is Cut Edge Corrosion?
Cut edge corrosion occurs where the pre-finished metal sheets are cut to size during installation. These exposed edges lose their protective coating, making them vulnerable to the elements. Over time, this exposure leads to:
- Rust and peeling: The raw metal begins to corrode, weakening the cladding and causing the protective coating to peel back further.
- Water ingress: The exposed and weakened edges become entry points for rainwater, leading to leaks and potential damage to the building’s structure and contents.
- Increased maintenance costs: Left untreated, cut edge corrosion can escalate into costly repairs or even necessitate complete roof sheet replacement.

Cut Edge Corrosion Coating Systems
Our cut edge corrosion coating systems are specifically designed for profiled metal roofing. We use flexible, UV-stable coatings that bond to both the factory finish and the bare metal at cut edges. The system moves with the roof through thermal cycles without cracking or delaminating, providing long-term protection against further corrosion. All our cut edge corrosion coatings carry manufacturer guarantees of up to 25 years.
Cut Edge Corrosion Repair Process
Our cut edge corrosion repair process starts with a detailed roof survey to assess the extent of the corrosion and identify any secondary issues such as failing fixings, blocked gutters, or damaged flashings. We then clean and prepare the affected areas, stabilise any active corrosion with specialist primers, and apply the sealing coat system. The work is carried out from roof level with no disruption to the building operations below.

Frequently Asked Questions
What causes cut edge corrosion?
Cut edge corrosion occurs where factory-coated metal sheets are cut to size during installation. The exposed raw metal edge loses its protective coating and begins to corrode when exposed to moisture and air.
How do I know if my roof has cut edge corrosion?
Look for rust staining at sheet overlaps, peeling or flaking paint at sheet edges, and water stains on the underside of the roof. If you can see rust lines running along the sheet laps from ground level, corrosion is already well established.
Can cut edge corrosion be repaired without replacing the roof?
Yes — in most cases, cut edge corrosion can be treated in situ without removing or replacing any sheets. Our treatment seals the corroded edges and prevents further deterioration, adding years of life to the existing roof.
How long does cut edge corrosion treatment last?
Our treatments typically provide 15-20 years of protection. The exact lifespan depends on exposure conditions and the severity of the original corrosion.
Is cut edge corrosion covered by insurance?
Cut edge corrosion is generally considered a maintenance issue rather than an insurable event. However, the water damage caused by untreated corrosion may be covered. Early treatment is far more cost-effective than claiming for water damage.
