Flat Roofing Systems We Install
We’ll recommend the right system based on the roof size, access, and how the space is used, so you’re not paying for the wrong solution.
EPDM Rubber Roofing
EPDM is a durable rubber membrane that performs well in UK weather and stays flexible over time. A great option for many Hertford flat roofs where reliability matters.
GRP Fibreglass Roofing
GRP gives a seamless, hard-wearing finish and works especially well on garages, dormers and smaller flat roofs when detailed correctly.
Torch-On Felt Roofing
Modern torch-on felt is a dependable choice when installed in proper layers with strong edge and joint detailing, ideal for many residential roofs in Hertford.
Liquid Flat Roofing Systems
Liquid systems are useful for awkward shapes and refurbishments, creating a fully bonded waterproof surface around trims, outlets and roof penetrations.

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.
