About Our Flat Roofing Work
Putney has a mix of older housing, terraces, conversions, and modern builds, which means flat roofs here vary a lot in structure and detailing. We work on small domestic roofs and larger areas, focusing on what actually keeps a flat roof watertight, correct drainage, durable materials, and careful finishing around edges, parapets, rooflights, and abutments. The goal is simple, a roof that performs properly and does not become a repeat problem.

Flat Roof Systems We Install in Putney
We install several proven systems and recommend the right one based on roof size, access, exposure, and budget, not a one-size-fits-all answer.
EPDM Rubber Roofing Putney
EPDM is a tough rubber membrane that works well on extensions and garages. It’s flexible, handles temperature movement, and is low maintenance when installed with proper trims and sealed upstands. It’s a strong choice for long-term waterproofing without constant upkeep.
GRP Fibreglass Roofing Putney
GRP creates a seamless finish that’s ideal for balconies, walk-on areas, and flat roofs where you want a neat, modern look. When correctly formed at edges and joints, it delivers reliable waterproofing and a clean finish that suits many residential properties.
Torch-On Felt Roofing Putney
Torch-on felt is a layered system that remains a solid option for many flat roofs. It’s cost-effective and durable when installed correctly, particularly on traditional roof builds where a robust, proven waterproof layer is needed.
Liquid Flat Roofing Putney
Liquid systems are especially useful on roofs with awkward detailing, multiple penetrations, or where an overlay is appropriate. The liquid cures into a seamless waterproof layer, reducing weak points and making it a practical option for refurbishments and complex shapes.

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 roof condition, drainage, and weak points, then explain what’s worth repairing and what isn’t.

We complete the work safely and cleanly, then check drainage, junctions, and finishing details before signing it off.
Frequently Asked Questions
If leaks are isolated and the structure is sound, repairs often make sense. If you have recurring leaks, soft spots, widespread cracking, or trapped moisture, replacement is usually the safer long-term option.
It depends on size, access, and detailing. EPDM is a strong low-maintenance choice, GRP suits roofs where a seamless finish matters, and felt can work well on traditional builds when installed properly.
No. Pooling is usually a design or installation issue. A properly built flat roof should have correct falls and drainage points to move water away.
Yes. Replacement is the best time to upgrade insulation and improve thermal performance, especially on older extensions and conversions.
Most small domestic flat roofs can be completed within a few days, depending on access, weather, and whether any deck repairs are needed.
Yes. Workmanship is guaranteed, and manufacturer-backed warranties may apply depending on the system installed.
