Flat Roofing Systems We Install
Every system has its place. We will talk you through what suits your roof best based on access, roof size, budget, and how long you want the solution to last.
EPDM Rubber Roofing
EPDM is a durable rubber membrane that handles movement and temperature changes well. It is a solid choice for many flat roofs in Reading because it is flexible, weather-resistant, and suited to both residential and commercial roofs.
GRP Fibreglass Roofing
GRP provides a seamless, hard-wearing finish that works well on smaller flat roofs like garages and dormers. Preparation is everything with GRP, so we focus on clean detailing and proper curing to avoid future cracking or weak spots.
Torch-On Felt Roofing
Modern torch-on felt remains a reliable option when installed in the correct layers with strong edge details. It is a cost-effective system that can perform well for years when the falls and trims are done properly.
Liquid Roofing Systems
Liquid-applied roofing is useful for awkward roof shapes, heavy detailing, or areas where sheet systems are difficult. Once cured, it forms a continuous waterproof layer, ideal for refurbishment work and complex roofs.
Why Flat Roofs Fail, and How We Prevent It
Most flat roof failures come down to poor drainage, rushed detailing around edges and rooflights, or repairs that do not address the underlying issue. We focus on correct falls, sound joins, and proper finishing so the roof stays watertight, even in heavy Reading rain.

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 start with a proper roof inspection and clear advice on the best next step.

You get a clear quote and a sensible schedule, with no vague pricing or guesswork.

We complete the work carefully, check weak points before we leave, and keep the site clean.
Frequently Asked Questions
It depends on the system and how well it was installed. Many flat roofs last 20 to 40 years, and regular inspections plus quick repairs can extend the lifespan.
Pooling usually means the falls are wrong, outlets are blocked, or the structure has dipped over time. It should be inspected because standing water speeds up wear and increases leak risk.
Often yes, if the roof is otherwise in good condition and the leak source is clear. If the membrane is failing across large areas, replacement may be more cost-effective.
EPDM is flexible and handles movement well, while felt can be a strong, cost-effective option when installed correctly in layers. The “best” option depends on the roof and budget.
A good rule is at least once every couple of years, and after major storms. This helps catch small issues early, especially around outlets and edges.
Yes. We cover Reading and surrounding areas within RG1 to RG30, including nearby villages and suburbs.
