More Information
Choosing a Flat Roofing System
Modern flat roofing has moved on a long way from traditional felt. We install felt, GRP fibreglass and single-ply membrane systems, each suited to different budgets and uses. GRP fibreglass is popular for its seamless, durable finish, while single-ply membranes offer excellent long term performance on larger areas. We help you choose the right system for your project.
Getting the Falls Right
One of the most common causes of flat roof failure is poor drainage. If a roof does not have enough fall, water pools instead of running off, which shortens the life of the roof covering. We design every flat roof with proper falls built in from the start, so water is directed away efficiently.
A Roof Built to Last
We fit flat roofs with careful attention to edge trims, upstands and junctions with walls, which are the areas most likely to let water in if not done properly. Getting these details right at installation means fewer problems and less maintenance for years to come.
ABOUT US
We installed a new GRP flat roof on a garden room in Ockley last year, replacing an old felt roof that had started to blister and let water through. The finished roof gave the homeowners a completely seamless surface with no joints for water to find its way through, and it has stayed watertight through the winter that followed.

Free, no-obligation quotes on every job

Careful, tidy work on properties of every age
We regularly work on homes tucked along the lanes around Box Hill, in the villages of Newdigate and Beare Green, and on properties close to the town centre near Denbies. From the older cottages near St Martin's Church to newer builds on the edge of Dorking, we know the roofing challenges this part of Surrey throws up, from clay soil movement to the weight of winter storms rolling in off the North Downs.
