About Our Flat Roofing Work in Oxfordshire
Across Oxfordshire, we often work on flat roofs for extensions, garages and older properties where original felt systems are now reaching the end of their life. We also see flat roofs fail early where drainage was never formed correctly, leading to ponding after heavy rain, or where edges and upstands were rushed and start to lift over time. Many Oxfordshire flat roof problems come down to the same issues, ageing coverings, weak detailing, and water not being directed away properly. Our work focuses on fixing those weak points properly so the roof performs as it should.

Flat Roofing Systems We Work With
The best flat roof system depends on the roof’s size, access, exposure, and whether it needs to handle regular foot traffic. We work with a range of flat roofing materials and will recommend the most suitable option for your property based on a proper inspection.
EPDM Rubber Roofing
EPDM is a durable rubber membrane that works well on many residential flat roofs such as extensions and garages. It handles movement without cracking and performs reliably in UK conditions when installed with correct preparation and secure edge detailing.
GRP Fibreglass Roofing
GRP fibreglass roofing creates a seamless, hard-wearing finish that suits many smaller flat roofs and areas where a tougher surface is useful. Applied correctly, GRP forms a strong waterproof layer and provides a clean, tidy finish around edges and detailing.
Torch-On Felt Roofing
Modern torch-on felt is a practical option for certain flat roofs when installed correctly with proper layering and clean detailing. The base preparation and edge finishing matter a lot, and done right, felt systems can be dependable and cost-effective.
Liquid Roofing Systems
Liquid roofing systems can be suitable where the roof has complex detailing or where an overlay approach is appropriate. They form a seamless waterproof coating and can be effective when installed with correct primers, reinforcement and curing conditions.

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

We assess the roof’s condition, identify the cause of any issues, and talk you through the options clearly so you can make a sensible decision.
We provide a straightforward quotation explaining what’s included. Once agreed, we book in the work around what’s practical for you and the job.
