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.
Why Putney Homeowners Choose Us?
People in Putney want work done properly, without drama. We show up, inspect the roof properly, explain the options clearly, and carry out repairs or replacements with tidy site standards. No scare tactics, no vague “needs doing” talk. Just straight answers, good workmanship, and a roof that does what it’s meant to do.

Feedback from customers who wanted reliable flat roofing with clear communication and a clean finish.
Removal of Chimney stack, replacement of roof underlay, guttering and flat roof repair. - Mitchell from Alliance Roofing & Building was the only builder, of many that I had contacted, that climbed a ladder to inspect my flat-roof and to climb into my loft-space to inspect the main roof from the inside. After an extensive review of my property and discussing my options, he emailed me his quotation on the same day. Booking in dates for Alliance & Roofing to commence work was quick and effortless. They arrived on time, completed the work as planned to a professional standard. Provided Photos of work carried out at all stages. I highly recommend Alliance Roofing & Building.

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.
