About Our Flat Roofing in Chobham
Chobham properties take a beating from wind and driving rain across the Common, plus heavy leaf fall from mature trees that blocks outlets and causes standing water. A lot of flat roof issues here come down to poor drainage, ageing felt systems, or rushed detailing around edges and rooflights. We focus on the basics that actually stop leaks, solid prep, correct falls, proper materials, and clean finishing.

Flat Roofing Systems We Install in Chobham
We’ll recommend the right flat roofing system based on your roof shape, access, budget, and how long you want it to last.
EPDM Rubber Flat Roofing Chobham
EPDM is a strong, flexible membrane that handles temperature changes well and performs reliably over time. It’s a great option for extensions and garages in Chobham where you want low maintenance and long-term waterproofing, with clean trims and tidy edges.
GRP Fibreglass Flat Roofing Chobham
GRP creates a seamless, hard-wearing finish that’s ideal for smaller flat roofs, bays, dormers and garages. It’s a good choice when you want a sharp look and a tough surface, especially where occasional foot traffic is needed for gutter access or maintenance.
Torch-On Felt Flat Roofing Chobham
Modern torch-on felt is nothing like the old stuff people remember. Installed in multiple layers, it’s dependable and cost-effective. It’s commonly used for garages and extensions where you want proven performance, strong waterproofing, and a system that’s straightforward to maintain.
Liquid Flat Roofing Systems Chobham
Liquid systems work well on awkward roofs with lots of detail, upstands, or penetrations where traditional sheets can struggle. The liquid cures into a continuous waterproof layer, reducing weak points. It’s often ideal for refurbishments where the roof shape is complex.
Why Chobham Homeowners Choose Us?
Because we do not overcomplicate it. We inspect properly, explain the options clearly, and do the work to a standard you can trust. We keep the site tidy, stick to what we agree, and focus on long-term fixes rather than quick patches that keep you calling back.

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
It depends on the system and how well it’s installed. EPDM and GRP can often last 20–30 years, while modern torch-on felt commonly lasts 15–20 years. Poor drainage and bad detailing can shorten any roof’s lifespan.
Often, yes. If the roof structure is sound and the issue is localised, a repair can be the best option. If leaks are coming from multiple areas or the roof is failing overall, replacement may be more cost-effective long term.
The most common causes are blocked outlets from leaf debris, standing water, failing seams, damaged edges, and poor detailing around rooflights or walls. Ageing felt roofs are also a common culprit.
Yes. If water is getting in, we can attend to stop the leak and protect the property, then recommend the right permanent repair.
EPDM and GRP are both popular for extensions. EPDM is flexible and low maintenance, GRP gives a seamless, hard finish. The best choice depends on roof size, access, and the detail around edges and rooflights.
Yes. We inspect the roof first, then provide a clear quote based on what’s actually needed. No guessing, no vague pricing.
