Flat Roofing Systems We Install
We’ll recommend the right system based on roof size, access, usage and budget, so you get the best long-term outcome.
EPDM Rubber Roofing
EPDM is a durable rubber membrane that performs well in UK weather and stays flexible over time. It’s a strong choice for extensions and garages where you want low maintenance and long lifespan.
GRP Fibreglass Roofing
GRP creates a seamless, hard-wearing surface with a clean finish. It’s ideal for smaller flat roofs like dormers, porches and garages when installed with the right trims and detailing.
Torch-On Felt Roofing
Modern torch-on felt is a reliable option when installed in proper layers with strong detailing at edges and joins. It’s a solid choice for many homes in Ealing, especially where budget matters.
Liquid Flat Roofing Systems
Liquid systems are great for awkward shapes, lots of roof penetrations, or overlay work. They create a fully bonded waterproof layer and a neat finish around trims and details.

Customers care about two things, does it stop the leak, and does it stay fixed. That’s what our reviews reflect.
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.
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.

Frequently Asked Questions
If you’re seeing recurring leaks, lifting edges, cracks, soft spots or standing water, it’s time for a proper inspection. We’ll tell you honestly whether a repair is worth it.
