Cut Edge Corrosion

Cut Edge Corrosion

Most metal roofs will fail at some point due to cut edge corrosion. During the manufacturing process the edges of the metal sheets are not treated with the same protective layer of coating  as the main body of the sheet. After a while the elements begin to erode the sheets from the cut edge inwards, leading to rust, deterioration, and ultimately leaks.


The affected areas need to be thoroughly cleaned and prepared for the chosen liquid treatment, After thorough preparation the edges are masked off and primed, and finally the seamless waterproof coat is applied,prevnting further decay and  leaving your roof waterproof and dependable.
