Felt Flat Roofing Farnborough
Modern multi-layer felt systems are far better than old-style felt roofs, and they’re still a great choice when you want strong waterproofing at a sensible price. We install and repair felt flat roofing in Farnborough for garages, extensions and dormers, with proper detailing around edges and outlets where failures usually start.
EPDM Rubber Roofing Farnborough
EPDM rubber roofing is flexible, durable, and performs well through cold snaps, heat, and heavy rain. It’s a smart option for flat roofs in Farnborough where you want a low-maintenance system with strong long-term weather resistance.
Fibreglass Roofing (GRP) Farnborough
GRP is a seamless system with a clean finish that suits extensions, porches and dormers. Installed correctly, GRP fibreglass roofing is highly resistant to leaks and cracking, and it’s ideal where neat detailing and a strong surface matter.
Tourch- on Flat Roofing in Farnborough
We also handle industrial flat roofing in Farnborough for units, warehouses and commercial buildings that need durable waterproofing without constant downtime. Whether it’s maintenance, repairs, or a full replacement, we work safely, keep communication clear, and aim for minimal disruption on site.
Liquid Roofing Systems Farnborough
Liquid roofing is ideal when you need a seamless waterproof layer over a flat roof with lots of awkward details, upstands, trims, outlets, and junctions. We install liquid roofing systems in Farnborough for repairs and refurb projects where a traditional membrane is harder to dress in cleanly. Once cured, it forms a flexible, watertight finish that helps protect against standing water, splits, and general wear, as long as the roof is prepped properly and the build-up underneath is sound.
Why Farnborough Homeowners Choose Us?
Most flat roof problems come from rushed installs, weak joins, and poor drainage. We do it properly, inspect first, explain the options clearly, and quote honestly. You get tidy work, solid materials, and a roof that’s built to stay watertight.

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 inspect the roof properly, show you what’s causing the issue, and explain the most sensible next step.

You get a clear quote, realistic timing, and a booked date that doesn’t keep changing.

We complete the work carefully, then check edges, joins and drainage so the roof is watertight before we leave.
Frequently Asked Questions
If the issue is localised and the decking is still solid, a repair may be enough. If the roof is repeatedly leaking, has widespread cracking, lifting, or feels soft underfoot, replacement is usually the smarter option. We confirm after an inspection.
Common causes are lifting edges, failed joins, cracked membranes, blocked outlets, and water pooling. Older repairs that were only temporary are another big reason leaks return.
It depends on the system and how well it was installed. Many modern flat roof systems can last for decades when installed properly and maintained, especially when drainage and edge details are done right.
Both can work well. EPDM is flexible and low maintenance, GRP is seamless with a crisp finish. The best choice depends on your roof layout and detailing, we’ll recommend what suits your roof, not what’s easiest.
Yes, but first we need to identify why it’s happening. Ponding is often caused by poor falls, sagging decking, or blocked drainage. We inspect and then recommend the correct fix.
Yes. We provide a free quote after assessing the roof, and we’ll explain what’s included so there are no surprises.
