Flat Roof Systems We Work With
We’ll recommend the best system based on your roof size, access, how the space is used, and your budget.
EPDM Rubber Roofing
A tough, flexible membrane that suits many residential flat roofs, especially where long-term weather resistance and low maintenance matter.
GRP Fibreglass Roofing
A seamless, durable option that’s ideal for smaller flat roofs and walk-on areas, giving a clean finish and strong waterproof protection.
Torch-On Felt Roofing
A proven multi-layer system when installed correctly, often chosen for garages and extensions where a reliable, cost-effective covering is needed.
Liquid Roofing Systems
Best for awkward details and refurbishment work, creating a continuous waterproof layer without the disruption of a full strip when 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 start with an inspection to identify the cause of the problem, then explain whether a repair or replacement is the smarter option.
You receive a clear written quote and a straightforward timeline, so you know what’s included before any work begins.

We complete the work neatly, then check seams, outlets and edges to confirm the roof is watertight before we leave.
