About Our Flat Roofing Services
Flat roofs are common across Weybridge, especially on extensions, garages and modern refurbishments. The problem is, many flat roofs fail early because corners were cut on drainage, edge detailing or materials. We take a straightforward approach, inspect properly, recommend the right system for the roof, and install or repair it with the kind of care you would expect on your own home.

Flat Roofing Systems We Install
Different roofs need different solutions. We help you choose the best option based on budget, lifespan expectations, roof shape and how the space is used.
EPDM Rubber Roofing
EPDM rubber roofing is a solid option for flat roofs in Weybridge because it stays flexible, handles temperature changes well, and resists cracking. It is also low maintenance and works especially well for garages, extensions and larger single-surface roofs.
GRP Fibreglass Roofing
GRP fibreglass roofing creates a seamless, watertight finish that is ideal for flat roofs where you want strength and a clean look. It is commonly used on garages and extensions and performs well when installed with the correct trims and fall to outlets.
Torch-On Felt Roofing
Modern torch-on felt is far better than older felt systems. It is cost-effective, dependable, and suits many residential flat roofs in Weybridge. Installed properly, it provides a strong waterproof layer and is a good option for replacements where budget matters.
Liquid Roofing Systems
Liquid roofing systems are useful for flat roofs with awkward shapes, detailed edges, or multiple penetrations. The coating bonds to the surface and forms a continuous waterproof layer, which makes it a good option for refurbishing existing roofs where stripping back is not always necessary.

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 assess the condition of the flat roof, check for common failure points, and explain whether a repair is realistic or whether replacement is the safer option.

You get a clear quote with the work set out properly, plus a realistic start date and timeframe, no vague promises.

We complete the work carefully, then carry out final checks on seals, outlets and edges, so the roof is properly finished before we leave.
Frequently Asked Questions
That depends on the system and how well it is installed. EPDM and GRP often last 20 years or more, while modern felt systems typically last around 10–15 years when installed correctly.
Often, yes. If the structure underneath is sound and the issue is localised, a repair can be the right solution. If the roof is failing across multiple areas, replacement usually works out better long term.
Common causes include failed seams, damaged trims, blocked outlets, poor falls that leave standing water, and old coverings that have cracked or blistered over time.
EPDM is popular for its lifespan and low maintenance. Felt is often more cost-effective and still reliable when installed well. The best choice depends on roof size, detailing, and budget.
Yes. If water is getting in, we can prioritise emergency repairs to stop the leak and protect the inside of your property.
Yes, and it is often worth doing. Adding or upgrading insulation during replacement can improve comfort and help reduce heat loss, especially on extensions and converted spaces.
