Flat Roofs Done Properly
Most flat roof failures come down to weak detailing and poor drainage, not “bad luck”. We focus on the parts that usually get rushed, edges, upstands, outlets, and falls, because that’s where leaks start. The result is a roof that holds up through heavy rain and temperature swings, without constant patch jobs.

Flat Roof Systems We Work With
We’ll recommend the system that suits your roof size, access, foot traffic and budget, then install it to a standard you can actually trust.
EPDM Rubber Roofing
A tough single-ply membrane that performs well on larger flat roofs. Flexible, UV resistant, and a strong option for long-term waterproofing.
GRP Fibreglass Roofing
A seamless, rigid finish that’s great for smaller roofs and details. Popular for dormers and balconies where clean edges matter.
Torch-On Felt Roofing
A reliable multi-layer system when installed properly. Often used for garages and extensions where you want proven performance at a sensible cost.
Liquid Roofing Systems
Ideal for awkward shapes or refurbishment work. Liquid systems create a continuous waterproof layer and can reduce disruption when the substrate is sound.

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, identify the failure point, and tell you what needs doing, and what doesn’t.
You get a clear written quote and a date, no vague pricing, no surprises.

We complete the work neatly, then check edges, seams and outlets to confirm it’s sealed and draining as it should.
