Flat Roof Systems We Install in Slough
We’ll recommend the right system based on how your roof is used, how it drains, and what condition it’s in.
EPDM Rubber Roofing in Slough
EPDM is a strong, flexible rubber membrane that suits many domestic flat roofs. It handles temperature changes well, resists cracking, and works especially well on simpler roof shapes. It’s a great option for garages and extensions where you want a clean, low-maintenance finish.
GRP Fibreglass Roofing in Slough
GRP creates a tough, seamless surface that is ideal for flat roofs that get a bit of foot traffic, like balconies and roof terraces. It’s installed with resin layers and topcoat, then finished with neat trims and detailing. Done properly, it looks sharp and performs well for years.
Torch-On Felt Roofing in Slough
Torch-on felt remains a popular choice because it’s reliable, cost-effective, and well-suited to many flat roof replacements. We use multi-layer systems and install them with correct overlaps and edge finishing, so you get proper waterproofing, not a quick patch-up.
Liquid Roofing Systems in Slough
Liquid systems are useful when the roof has awkward details, lots of upstands, or areas where a seamless finish helps prevent leaks. The coating forms a continuous waterproof layer once cured. It can be a smart solution for specific roof types, especially when detailing is the main challenge.

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 look at the roof covering, edges, outlets, and any weak spots around rooflights or joins, then tell you plainly whether it’s a repair job or if replacement is the smarter option.
You’ll get a clear written quote that spells out what’s included, what isn’t, and the expected timeline, then we’ll book a date that suits you and keep you updated if anything changes.

Whether it’s a small flat roof repair or a full rebuild, we work cleanly, protect the area, and finish with final checks on drainage, seals, and detailing so you’re not dealing with the same issue again next month.
