Flat Roofing Work in Woodstock, Done Properly
Woodstock has a mix of older properties, newer extensions, and flat-roofed garages where poor historic installation can cause recurring issues. We see the same problems again and again, cracked coverings, weak joins, blocked drainage, and roofs that were never given the correct fall. Our approach is built around identifying why the roof failed, then putting in the right fix so it holds up long term.

Flat Roof Systems We Install and Repair
Not every flat roofing material suits every roof. We’ll explain your options clearly, then recommend a system that fits the roof type, the level of foot traffic, and how long you want it to last.
EPDM Rubber Roofing
EPDM is a strong choice for many flat roofs in Woodstock because it handles temperature changes well and stays flexible over time. It’s particularly good for larger, simpler roof areas where you want a clean finish and low maintenance. Installed correctly, it offers excellent weather resistance and long-term reliability.
GRP Fibreglass Roofing
GRP works well where you need a tough, seamless finish, especially on roofs that see occasional foot traffic or have awkward detailing. The key is correct preparation and installation conditions. Done properly, GRP provides a solid surface that resists water ingress and stands up well over time.
Torch-On Felt Roofing
Torch-on felt remains a popular option for garages and extensions because it’s cost-effective and reliable when installed using modern multi-layer systems. The difference between a felt roof that lasts and one that fails early usually comes down to detailing at the edges and correct bonding between layers.
Liquid Roofing Systems
Liquid systems are useful for roofs with lots of penetrations, awkward shapes, or areas where seamless waterproofing is the best route. Preparation matters more than anything with liquid systems. If the base is not sound, the finish will not last. When used in the right scenario, it’s a very effective solution.
Why Flat Roof Problems Keep Coming Back?
A lot of flat roof issues aren’t caused by one big event, they’re caused by small weaknesses that are ignored or patched badly. Pooling water after rainfall, weak joins at edges, or repairs that were applied without fixing the underlying problem usually lead to repeat leaks. We focus on stopping the cycle, not feeding it with endless call-outs.

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 don’t quote blindly. We inspect the roof, explain what we’ve found in plain English, and recommend the right solution based on what the roof actually needs.
You’ll get a clear quote with the work outlined properly, then we’ll agree a date that works for you. No vague pricing, no pressure, and no surprises.

Every job finishes with proper final checks, watertight detailing, and a tidy site. The goal is that you don’t need to think about your roof again once we’re done.
