A comprehensive choice of roofing accessories, including eaves, ridge and roof tile ventilators, completes the lightweight roofing system which is totally dry fixed throughout. Each roof tile has a downturned front edge and an upturned rear edge, and is profiled to provide a strong overlapping and interlocking roof covering. Decra’s lightweight roofing tiles are produced in large format. This enables faster installation with fewer fixings compared to traditional tile or slate roofing, but with none of the inherent disadvantages of long run roofing sheets. Once installed Decra lightweight roof tiles provide a durable weathertight and low maintenance roof.
