Flat Roofing Systems We Work With
Different flat roofing systems suit different buildings. We explain the pros and limitations of each option so you can make an informed decision without sales pressure.
EPDM Rubber Roofing
EPDM rubber roofing is well suited to larger flat roofs and extensions. With fewer joins and strong resistance to weathering, it provides consistent performance and low maintenance over time.
GRP Fibreglass Roofing
GRP fibreglass roofing creates a seamless, rigid surface that works well on smaller flat roofs and detailed areas. When installed correctly, it offers a clean finish and strong waterproofing.
Torch-On Felt Roofing
Modern torch-on felt systems remain a practical option for many residential flat roofs. Installed in proper layers with attention to edges and outlets, they provide dependable protection at a sensible cost.
Liquid Roofing Systems
Liquid roofing systems are ideal for complex flat roofs with multiple penetrations or awkward detailing. Applied as a seamless coating, they reduce weak points and extend the life of existing roofs where suitable.

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 begin every job with a proper inspection of the flat roof, checking the surface, edges, drainage points, and surrounding details so we understand the real issue before recommending work.

You receive a clear written quote outlining the work required and a realistic schedule, so you know exactly what to expect before any work begins.

Once work is complete, we carry out final checks on seals, drainage, and finishes to ensure the flat roof is watertight, tidy, and ready to perform.
