About Our Flat Roofing
Flat roofs are common around Brixton, especially on rear extensions, garages and dormers. Most failures come from rushed detailing, bad falls, or weak edges. We focus on the parts that stop leaks long-term, drainage, joints, outlets and finishing, so your roof performs properly in real weather, not just on install day.

Flat Roofing Systems We Offer
Different buildings need different systems. We install and repair several flat roofing options in Brixton, and we’ll recommend what fits your roof and budget.
EPDM Rubber Roofing
EPDM rubber roofing is a strong choice for many Brixton flat roofs, especially larger extension and garage roofs. It stays flexible, handles temperature changes well, and gives reliable waterproofing when fitted with proper edge details.
GRP Fibreglass Roofing
GRP fibreglass roofing creates a neat, seamless finish, which makes it a great option for smaller roofs like dormers and porches. It’s tough, tidy-looking, and ideal when you want a clean finish that stays watertight.
Torch-On Felt Roofing
Torch-on felt can still be a solid system when installed properly using a multi-layer build. We take extra care around corners, edges and outlets, because that’s where cheap felt jobs usually fail first.
Liquid Roofing Systems
Liquid roofing systems work well on awkward shapes, roof penetrations, and details where sheet materials struggle. Applied as a seamless coating, they create a continuous waterproof layer and can be ideal for repair situations.
Why Brixton Homeowners Choose Us?
People in Brixton want straight answers, clean work, and no mess left behind. We explain what’s wrong, what it takes to fix, and what it will cost, then we do the job properly. No vague “it should be fine” advice, and no pressure tactics.

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, including edges, flashings, outlets and the membrane condition, then explain your options clearly.
You get a clear written quote and a realistic timeline. If the issue is urgent, we prioritise the repair and keep you updated.

Once the work is complete, we check the critical points again, joints, drainage, edges and upstands, then confirm everything is sealed and finished correctly.
