Flat Roof Repair and Installation in Wokingham
Our Services
Flat Roofing for Wokingham Properties
Wokingham has a mix of modern estates, older houses with extensions, and busy commercial spaces, and flat roofs behave differently on each. We recommend systems based on how the roof is used, foot traffic, sun exposure, and drainage, so you end up with a roof that performs, not one that needs constant attention.

Flat Roofing Systems We Offer
Choosing the right material matters. We explain the pros and cons in plain English and match the system to your roof, whether you want maximum lifespan, lowest maintenance, or the best value.
EPDM Rubber Roofing
EPDM rubber is a strong choice for many flat roofs in Wokingham. It is flexible, handles temperature changes well, and can be installed with fewer joins, which reduces common leak points.
GRP Fibreglass Roofing
GRP creates a seamless finish that works well for garages, dormers, and extensions. Preparation is everything with GRP, so we take care with the base, trims, and curing, which is where many installations fall short.
Torch-On Felt Roofing
Torch-on felt is still a reliable system when installed properly in layers with clean detailing at edges and outlets. It is a good option for those who want a proven system with solid value and straightforward maintenance.
Liquid Roofing Systems
Liquid-applied systems are ideal for awkward roof shapes, roofs with lots of penetrations, or refurbishment work where a continuous waterproof layer is needed. Once cured, it forms a seamless barrier that helps reduce leak risk around tricky areas.
Why Flat Roof Issues Keep Coming Back
Most repeat flat roof problems are caused by two things, water that has nowhere to go, and repairs that only cover the surface. We focus on drainage, edge detailing, and the condition of the deck underneath, so the fix lasts longer than a single winter.

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.

Frequently Asked Questions
That depends on the system and how well it was installed. Many flat roofs last 20 to 40 years, and regular inspections help extend lifespan by catching small issues early.
Common signs include bubbling or splitting, water pooling, damp patches on ceilings, cracking around edges, or leaks after heavy rain. If you spot any of these, it is worth getting it checked before damage spreads.
If the damage is localised and the roof structure is sound, repairs can be effective. If the membrane is failing across large areas or the roof is near the end of its life, replacement is usually the smarter long-term choice.
Yes, EPDM is popular because it is durable, flexible, and has fewer joins than many alternatives. It is often a strong option for garages, extensions, and larger flat roofs.
Yes, but it is usually simple. Keeping outlets clear and having the roof inspected every couple of years helps prevent ponding water, blocked drainage, and small defects turning into leaks.
Yes. Alongside Wokingham RG40 and RG41, we also cover nearby areas including Winnersh, Earley, Twyford, Woodley, Finchampstead, and surrounding villages.
