Clad-IT are roof refurbishment specialists and are approved applicators for a range of cut edge corrosion coating systems to provide longterm watertight and corrosion free guarantees.
Cut Edge Corrosion
Years ago, corrugated steel roofing sheets were merely just an agricultural installation product for barns and buildings and never really inspected. Now metal roof and wall cladding is widely used for commercial building elevations for roofs. Warehouses, retail units, hospitals and even modern apartment blocks and offices as a cost effective weather proofing aesthetic layer.
It is estimated that 60% of cladded buildings in the UK have cut edge corrosion, but many owners of commercial and industrial properties are not aware their business suffers from this problem and they often are not aware of what cut edge corrosion is and the effects that it can have to the water integrity of a building.
Why edge peel and cut edge corrosion
Within the metal cladding process, the corrugated metal sheets are coated in plastic such as a plastisol finish and the plastisol roof sheet coating prevents the underlying metal from being corroded by the elements and also improves the roof sheets aesthetical appearance in a range of standard and specialist colours.
When roof and wall cladding is procured from the steel rollers it is cut to the required size at the factory before delivery to site, the cut edge was not treated and is not protected or coated. It was then discovered years down the line that when the cut edge is exposed to oxygen and the elements it creates wide spread edge lap corrosion which is exacerbated by water and pollutants. Consequently, the roof lap cut edge corrosion continues to fail so that the corrosion becomes widespread as far as the first set of roof fixings, allowing water ingress and the potential of roof sheet loss via wind uplift.
The Repair Process
Clad-IT are roof refurbishment specialists and are approved applicators for a range of cut edge corrosion coating systems to provide longterm watertight and corrosion free guarantees. Clad-IT can treat cut edge corrosion to prolong the life expectancy of the roof cladding. Whilst surveying the cut edge corrosion clad-IT can complete a full roof survey and advise on other areas of remedial roof repairs that are required.
