About Our Flat Roofing
Flat roofs are common in Tadley on rear extensions, garages and outbuildings, and most failures come down to poor detailing rather than the material itself. We focus on the areas that stop leaks long-term, drainage, edges, joints and flashings, and we explain your options clearly so you know what you are paying for.

Flat Roofing Systems We Offer
Not every flat roof should be treated the same. We install and repair several systems in Tadley, and we will recommend what makes sense for the roof you have, not a one-size-fits-all answer.
EPDM Rubber Roofing
EPDM rubber roofing is a strong option for many Tadley properties, especially larger extension and garage roofs. It stays flexible, handles temperature changes well, and provides reliable waterproofing when finished properly at edges and outlets.
GRP Fibreglass Roofing
GRP fibreglass roofing is ideal for smaller roofs where a seamless finish matters, such as dormers, porches and compact extensions. Done properly, it creates a clean, watertight surface with a neat, modern look.
Torch-On Felt Roofing
Torch-on felt is still a solid choice when installed as a proper multi-layer system. We pay attention to the points where felt jobs usually fail, corners, edges, upstands and drainage, so the roof performs properly, not just on day one.
Liquid Roofing Systems
Liquid roofing systems can be a great solution for awkward roof shapes, lots of penetrations, or refurbishment work where stripping everything back is not ideal. Applied as a seamless coating, it creates continuous waterproof protection across the roof surface.
Why Tadley Homeowners Choose Us?
You do not want a roofer who guesses. You want someone who explains what has failed, what it takes to fix it, and what it will cost, then leaves your property tidy. That is how we work in Tadley, clear communication, clean workmanship, and repairs that actually solve the problem.

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.

Frequently Asked Questions
It depends on the system and the quality of the install. Felt is often around 10 to 15 years, while EPDM and GRP can last much longer when fitted correctly and maintained.
If the issue is local and the rest of the roof is in decent shape, a repair can be enough. If there are repeated leaks, widespread cracking, lifting edges, ponding water, or soft decking, replacement is usually the smarter choice.
Most leaks come from weak points, joints, edges, outlets, flashings, or areas where water sits for too long. That is why diagnosis matters, not just slapping on a patch.
