Flat Roofing Options in Wallingford
We’ll recommend a system based on your roof, not what’s easiest to sell. That includes how the roof drains, whether it needs to take foot traffic, and how long you want the result to last.
EPDM Rubber Roofing Wallingford
EPDM is a flexible rubber membrane that suits many flat roofs because it handles movement well and resists splitting. It’s a solid choice for garages, extensions, and larger flat areas when installed with clean detailing and proper sealing.
GRP Fibreglass Roofing Wallingford
GRP gives a seamless, hard-wearing finish that works well on smaller roofs and areas where you want a crisp edge detail. It’s ideal for many extensions and garages, as long as the base is prepared properly and the system is installed in the right conditions.
Felt Flat Roofing Wallingford
Modern felt systems are still a dependable option. Installed in layers with correct laps, trims and heat bonding, felt provides a practical balance of durability and value, and it’s often repairable if damage is caught early.
Industrial Flat Roofing in Wallingford
We also work on commercial and industrial flat roofs in Wallingford, including offices, storage units and larger roof spans. These jobs need careful planning, safe access, and materials suited to bigger surfaces and heavier exposure. We install, repair, and maintain industrial flat roofs with minimal disruption.
Why Flat Roofs in Wallingford Start Leaking
Leaks usually start at the weak points, edges, joins, rooflights, and outlets. Another common issue is ponding water, which speeds up wear and finds its way through poor detailing. The fix is rarely “more sealant”. The fix is correct diagnosis and correct repair.

New roof on my bungalow - I recently had the pleasure of working with Alliance Roofing and Building to install a new roof on my bungalow, and I couldn't be more satisfied with the results. From start to finish, the entire process was smooth and professional. Mitchell, who led the project, was exceptional. His expertise and dedication were evident from the moment he arrived. He and his team were not only highly skilled but also incredibly helpful and courteous throughout the entire job. They took the time to answer all my questions
Leak in the roof- Very polite and professional. Job was completed professionally at a very good price. Would highly recommend
Tile realignment/repair and felt renewal - Mitchell and his team were excellent. Would definitely recommend Alliance. The team were on time (in fact they were able to begin the job half a day earlier than initially discussed), polite, efficient and kept us informed of progress each day. We could not have asked for a better service.
Roof tile replacement and chimney repair - Mitchell and his team are reliable, efficient and hard working. We will certainly use them again in the future. Thanks guys
New slate roof - Mitchell and his team installed my new roof and I'm very satisfied. The quality is superb, they were professional, punctual, and communicative. The project finished on time and the site was left spotless.
We inspect the roof properly and tell you what’s going on, no vague guesses, no hard sell.
You get a clear quote and a realistic plan for getting the work done with minimal disruption.

We finish with checks on edges, joins, outlets and flashings, then leave the site tidy.
