Cut Edge Corrosion Treatment

Preventative Protection for Industrial and Commercial Roofs

Cut edge corrosion is one of the most common — and often overlooked — issues affecting profiled metal roofing systems. It typically begins at the exposed edges of roof sheets where they’ve been cut to size during manufacture or installation. These vulnerable edges, especially at sheet overlaps and eaves, are exposed to years of weathering, UV damage, and capillary-held water — creating the perfect conditions for corrosion to take hold.

At AB Roofing Solutions, we specialise in the identification, treatment, and prevention of cut edge corrosion on both pitched and flat metal roofs. Left untreated, this progressive condition can lead to widespread coating failure, delamination, and even complete sheet corrosion — resulting in costly replacements and possible water ingress.

How Cut Edge Corrosion Happens

Cut edge corrosion most commonly affects:

• Sheet laps and eaves where water collects or capillary action traps moisture

• Roof sheets damaged by foot traffic or poor installation

• Aged or poorly maintained systems where coatings have started to break down

In many cases, early-stage corrosion is first spotted during a planned maintenance inspection, roof survey, or dilapidation assessment — especially when a tenant is preparing to hand back a commercial property.
