Our Customer Helpline
Flashings are an integral part of any sheeted roof, covering the ridge where the two sides of a pent roof meet, closing off the corners and ends of runs of sheets, creating an apron where a roof abuts a wall or sealing off reveals such as doors and windows. We stock standard 90º corner or 130º ridge flashings in popular colours and fabricate other flashings to customer’s requirements in our workshop. Flashings are generally fitted directly to the high point of the profiled sheet using self drilling stitching TEK screws (ST22) that has a coarse thread that joins two pieces of sheet metal together. Flashings are normally available in 3m lengths. They should be fitted with a 150mm overlap.
