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.
Why Homeowners in Weybridge Choose Us
People do not want a sales pitch when their roof is leaking, they want straight answers. We turn up, inspect properly, explain what is going on in plain English, and recommend what makes sense for the roof and the budget. We keep the site tidy, respect your property, and finish the job to a standard you would actually feel confident recommending.

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
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.
