Flat Roof Repair and Installation in Newbury
Our Services
Flat Roofing Built for Newbury Properties

Flat Roofing Systems We Offer
Each flat roofing system has strengths and limitations. We explain the options clearly and help you choose the right system based on durability, maintenance expectations, and overall value.
EPDM Rubber Roofing
EPDM rubber roofing is flexible, durable, and well suited to Newbury’s changing temperatures. It resists cracking, handles movement well, and provides a long-lasting waterproof finish for both residential and commercial flat roofs.
GRP Fibreglass Roofing
GRP fibreglass roofing creates a seamless, rigid surface that works particularly well on garages, dormers, and extensions. Correct preparation is critical, and we focus on strong detailing to avoid future stress cracks.
Torch-On Felt Roofing
Modern torch-on felt systems are far removed from older felt roofs. When installed in multiple layers with secure edges and correct falls, they provide a cost-effective and dependable flat roofing solution.
Liquid Roofing Systems
Liquid-applied roofing is ideal for complex roof shapes or refurbishment projects. It forms a continuous waterproof layer once cured, making it useful where traditional sheet systems are difficult to install cleanly.
Why Flat Roofs Fail and How We Avoid It
Most flat roof problems come from poor drainage, rushed installation, or repairs that ignore the real cause. We focus on water flow, structural condition, and proper detailing, which is why our flat roofs in Newbury hold up over time.

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

Frequently Asked Questions
Depending on the system and installation quality, flat roofs can last anywhere from 20 to 40 years. Regular inspections and prompt repairs help maximise lifespan.
Standing water is usually caused by poor falls, blocked outlets, or structural movement. It should be inspected, as ponding accelerates wear and increases leak risk.
If the roof structure is sound and damage is localised, repairs are often effective. Widespread membrane failure usually means replacement is the better long-term option.
EPDM offers flexibility and long-term durability, while felt can still be a strong choice when installed correctly. The best option depends on roof use, budget, and expectations.
Every couple of years is sensible, and after severe weather. Inspections help catch issues early, especially around outlets and edges.
