Flat Roofing Systems We Work With
Different flat roof systems suit different properties. We help you understand the options and recommend a solution based on durability, budget, and the demands placed on the roof.
EPDM Rubber Roofing
EPDM rubber roofing is a popular choice for flat roofs in Abingdon-on-Thames due to its flexibility and resistance to cracking. It performs well in varying temperatures and is well suited to larger roof areas where a clean, low-maintenance finish is needed.
GRP Fibreglass Roofing
GRP fibreglass roofing creates a seamless, rigid surface that works well on flat roofs with complex detailing or areas that require occasional access. Correct preparation is essential, and when installed under the right conditions, GRP offers strong water resistance and durability.
Torch-On Felt Roofing
Modern torch-on felt systems remain a dependable option for garages and extensions. When installed using multi-layer methods with proper edge detailing, felt roofing provides solid protection and good value for money over its lifespan.
Liquid Roofing Systems
Liquid roofing systems are ideal for flat roofs with awkward shapes, multiple penetrations, or limited access. They form a continuous waterproof layer, but only perform well when the underlying surface is properly prepared and stable.
Why Flat Roof Issues Are Common on Older Properties?
Many flat roof problems develop gradually rather than overnight. Small defects, standing water, or poorly executed past repairs can slowly weaken the roof until leaks appear inside. Addressing these issues early helps avoid repeated damage and unnecessary expense later on.

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

We could not have asked for a better service.
