About Our Flat Roofing
Flat roofs are common across Whitchurch homes, particularly on extensions, garages and dormers. The difference between a flat roof that lasts and one that constantly leaks comes down to preparation, drainage and correct system choice. We focus on doing the job properly the first time, using proven materials and clean workmanship rather than short-term fixes.

Flat Roofing Systems We Offer
We install a range of flat roofing systems to suit different roof sizes, layouts and budgets, ensuring the right solution for each Whitchurch property.
EPDM Rubber Roofing
EPDM rubber roofing is a flexible, low-maintenance system ideal for larger flat roof areas. It handles temperature changes well and offers excellent resistance to cracking, making it a popular choice for Whitchurch homeowners looking for longevity.
GRP Fibreglass Roofing
GRP fibreglass roofing creates a seamless, rigid surface with a clean finish. It works particularly well for garages, balconies and extensions where a modern look and strong waterproof protection are required.
Torch-On Felt Roofing
Torch-on felt roofing remains a reliable option when installed correctly. We use multi-layer systems with careful detailing around edges and outlets to reduce the common failure points seen on rushed felt installations.
Liquid Roofing Systems
Liquid flat roofing systems are ideal for complex roof shapes and detailed areas. Applied cold, they cure into a seamless waterproof layer that is effective for overlays and awkward roof layouts.

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 by inspecting your flat roof properly and explaining what’s causing the issue. If a repair makes sense, we’ll say so. If replacement is the better option, we’ll explain why.

You receive a clear written quote covering materials, labour and timescales. Once approved, we schedule the work around your availability and keep you informed throughout.

All work is carried out safely and with minimal disruption. Once finished, we check drainage, joints and edges, then walk you through the completed work and aftercare advice.
Frequently Asked Questions
Persistent leaks, soft areas underfoot, lifting edges or widespread cracking usually indicate the roof is nearing the end of its lifespan. An inspection confirms whether repair or replacement is best.
There’s no single best system. EPDM suits larger areas, GRP works well on smaller roofs, felt remains cost-effective, and liquid systems handle complex shapes. The right choice depends on your roof and budget.
Most garage or extension flat roofs can be completed within one to two days, depending on size, access and whether decking or insulation needs replacing.
Temporary weatherproofing is sometimes possible, but permanent repairs depend on conditions. We won’t carry out work that’s likely to fail.
Basic maintenance such as keeping outlets clear and checking after storms helps prevent damage. Occasional inspections can avoid costly repairs later.
Yes. We provide free inspections and clear quotes so you can make an informed decision without pressure.
