What Is Cut Edge Corrosion And Why It Needs Treating

Cut edge corrosion is a common issue affecting metal roof cladding systems, particularly on older industrial and commercial buildings. If left untreated, it can lead to serious roof damage and costly repairs.

At All Aspect Coatings, we specialise in cut edge corrosion treatment for commercial and industrial roofing systems across the UK.

What Causes Cut Edge Corrosion?

Cut edge corrosion occurs when the protective coating on metal roofing sheets begins to deteriorate along the edges of the panels. Over time, exposure to moisture and oxygen causes the metal to oxidise, leading to visible rust and deterioration.

This issue is especially common in older buildings where roofing materials have been exposed to the elements for many years.

Early Signs of Cut Edge Corrosion

Some of the most common warning signs include:

• Rust along the edges of roof sheets
• Peeling or flaking coatings
• Discolouration on metal panels
• Visible corrosion on roofing seams

If these issues are not addressed early, the corrosion can spread across the roof.

Why Treatment Is Important

Treating cut edge corrosion early can prevent major structural damage. If corrosion spreads too far, it may require complete roof sheet replacement.

Professional treatment restores the affected areas and applies protective coatings that prevent the corrosion from returning.

The Cut Edge Treatment Process

The process typically involves:

1. Removing loose rust and damaged coating
2. Preparing the surface for treatment
3. Applying specialist corrosion inhibitors
4. Applying protective coatings to seal the edges

This process restores the roof and prevents further corrosion.
