About Our Flat Roofing in Witney
Flat roofs are common across Witney, especially on extensions, garages, dormers and bay roofs. The problem is that older flat roofs were often built with poor drainage and tired materials, so water sits, joints fail, and small issues turn into bigger repairs. Our approach is simple, use the right system for the roof type, install it properly, and finish the details well so the roof stays watertight through Witney’s wet winters and shifting temperatures.

Flat Roof Types We Install and Repair in Witney
Different flat roofing systems suit different roof shapes, budgets, and levels of foot traffic. Below are the main options we work with across Witney, and we will recommend the one that fits your property, not the one that is easiest for us.
EPDM Rubber Roofing in Witney
EPDM is a strong rubber membrane that works well for many garage and extension roofs. It is flexible, handles temperature changes well, and gives a clean finish when installed with proper edge trims and drainage. EPDM is a solid choice if you want a reliable system with minimal maintenance.
GRP Fibreglass Roofing in Witney
GRP creates a hard, seamless surface which is ideal where you want a tough, tidy finish. It is often used on smaller flat roofs, dormers, and balconies, particularly when good detailing around edges and outlets is needed. When installed on a sound deck with the right build-up, GRP offers long-term waterproofing and a smart finish.
Torch-on Felt Roofing in Witney
Modern torch-on felt is not the flimsy stuff people remember from years ago. A proper multi-layer felt system is durable, cost-effective, and well suited to many flat roofs around Witney, especially where you want a proven option without overcomplicating the job. The key is correct layering, neat seams, and tidy edge work so water cannot track underneath.
Liquid Roofing Systems in Witney
Liquid roofing systems create a seamless waterproof layer, which makes them a strong option for flat roofs with awkward details, joints, or around outlets. They’re often used on refurb jobs where you need a clean, watertight finish without lots of joins that can fail over time. Once applied and cured, the coating forms a durable barrier that helps protect against leaks and standing water.

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 start by checking the problem properly, not guessing from a photo. We look at the membrane condition, edges, drainage points, and any signs of trapped moisture, then explain what’s causing the issue and what your realistic options are.
Once we know what the roof needs, you get a clear quote that explains the work in plain English. If you want to go ahead, we agree a date that suits you, and we confirm what access we need and what to expect on the day.

We complete the work neatly and safely, keeping disruption to a minimum. When the job is finished, we check the details that usually get rushed, edges, joins, outlets, and water run-off, so you are not left with a “looks fine” roof that fails later.
