Flat Roofing
GRP fibreglass, EPDM rubber and liquid rubber systems for extensions, garages, dormers and commercial roofs.
Flat Roofing across the South East
Water sits on a flat roof longer than on a pitched one, so a small split, a lifted edge or a sagging deck turns into a leak quickly. Older felt roofs crack and blister with age.
We install and repair flat roofs on homes and commercial buildings, including GRP fibreglass, EPDM rubber and liquid rubber systems, with a new deck laid first where the old one has had it.

What usually goes wrong
Puddles that sit after rain
Standing water finds every weak spot and shortens the life of the covering.
Damp in the extension ceiling
Flat roof leaks often show up well away from where the water gets in.
An old felt garage roof
Felt cracks, lifts and lets water into the deck underneath.
