Flat Roofs in Dursley

Which Flat Roof System Suits You?

Garage roofs, extensions and dormers in Dursley are where most flat roof leaks start. We strip back to the joists, lay new decking with a proper fall, and finish in torch-on felt, EPDM rubber or GRP fibreglass, whichever suits the roof and how you use it.

Most flat roof failures start below the surface. Water sits in a dip where the decking has sagged, a joint in the old covering opens up, and the boards underneath soften until the ceiling stains. A new flat roof replaces the lot: we strip back to the joists, check them, lay fresh decking and build in a fall that carries rain off to the outlet or gutter rather than leaving it to sit.

We fit three systems. Torch-on felt is the traditional choice and handles foot traffic well. With EPDM rubber, one sheet usually covers the whole field of the roof, leaving no joints in it. GRP fibreglass cures into one hard, glossy skin that suits balconies and awkward detailing. We talk through each with you at the roof, because the right one depends on the size, the shape, the access and what sits on top.
