Cut Edge Corrosion Treatment Specialists in South Yorkshire
South Yorkshire's steel industry heritage has left a lasting mark on the region's commercial building stock. The same era that produced the steel also produced the factories, sheds, and industrial units that housed the workforce, many of which are still in use today. The profiled metal roof sheets installed on these buildings during the 1970s, 1980s, and 1990s were cut to length on site, leaving exposed raw metal edges. Over decades of exposure to South Yorkshire's wet and often acidic atmospheric conditions, these cut edges are now the primary point of failure on thousands of commercial roofs across Sheffield, Rotherham, Barnsley, and Doncaster.
Cut edge corrosion begins at the bottom edge of each roof sheet where water runs off and the exposed metal is in permanent contact with moisture. The galvanised coating degrades first, followed by rust propagation into the base metal of the sheet. Left untreated, corrosion spreads several centimetres up the sheet face, compromises the structural integrity of the profile, and eventually causes through-sheet corrosion that allows water ingress into the building. The critical insight is that treatment works, and works economically, when applied at the early to mid stages of corrosion. By the time sheets are perforating, the cost-benefit equation shifts towards re-sheeting.
Our cut edge corrosion treatment programme for South Yorkshire buildings follows a rigorous five-stage process: cleaning and degreasing, mechanical preparation of corroded areas, application of specialist rust-inhibiting primer, application of reinforced mastic tape to the cut edge, and application of a two-coat polyurethane or acrylic topcoat system matched to the existing roof colour. The result is a fully sealed, weathertight cut edge that performs to the same standard as the original factory finish, but with a 20-year guarantee.
From our Hellaby, Rotherham headquarters, we cover all of South Yorkshire for cut edge corrosion treatment with rapid mobilisation. We work on all standard metal roof profiles, including Trisomet, Kingspan, Metecno, Ward, and a wide range of generic profiles, and our teams are experienced with both standing seam and through-fixed systems. Surveys are free, no obligation, and typically completed within 48 hours of enquiry.

How do I know if my South Yorkshire commercial roof has cut edge corrosion?
The most visible signs are orange or brown rust staining running down the face of the roof sheets from the lower cut edge, dark streaking on the building's external walls below the roof line, and visible pitting or flaking of the sheet surface at the bottom edge. If you can see daylight through the sheets from inside the building, the corrosion has progressed to the point where treatment may no longer be the most cost-effective option and a full survey is essential.
Is cut edge corrosion treatment cheaper than replacing the roof?
In most cases, significantly cheaper, typically 60 to 80% less than full re-sheeting. Treatment is the economically rational choice at the early to mid stages of corrosion where the sheet profiles are still structurally sound. Our survey will assess the extent of corrosion and provide an honest recommendation on whether treatment, partial re-sheeting, or full replacement is the right course of action.
How long does cut edge corrosion treatment last?
Our treatment systems are guaranteed for 20 years via a guarantee. The treatment halts active corrosion, seals the cut edge, and applies a durable polymer coating that prevents moisture re-entry for the full guarantee period. With correct ongoing maintenance, primarily keeping gutters clear so water drains freely off the roof, the treatment regularly lasts beyond the guaranteed term.
