Roof Sheet Flashings & Weatherproofing

Roof sheets cover the main area of your roof, but they can’t finish every edge, join or change in direction on their own. Roof sheet flashings are used in these exposed areas to help close gaps, direct rainwater away and create a more complete finish.

We've got flashings for the most common sheet roof details, including ridges and hips, valleys, verges, barge edges, eaves and wall abutments. Each one is designed for a different part of the roof, whether you’re finishing the top ridge line, protecting an exposed side edge, joining sheets into a valley or weathering the point where your roof meets a wall.

Choosing the right flashing depends on the sheet material, profile and roof layout. Corrugated roofing, box profile, tile-effect, bitumen, fibre cement and polycarbonate sheets can all need different finishing parts, even when they’re used in similar areas of a roof.

Start by choosing the part of the roof you need to finish, then check the flashing is suitable for your sheet type, profile and fixing method.
