Flat Roof Repair and Installation in Bracknell
Our Services
Flat Roofing for Bracknell Homes and Businesses
Bracknell has everything from newer developments to older properties with extensions and garage roofs, and flat roofing needs to suit the building, not a one-size-fits-all approach. We help you choose the right system based on foot traffic, sun exposure, roof size, and how the roof drains, so it performs properly year after year.

Flat Roofing Systems We Offer
Different roofs suit different materials. We walk you through the options in plain English, then recommend the best fit for your roof, your budget, and how long you want it to last.
EPDM Rubber Roofing
EPDM rubber is a strong option for many flat roofs in Bracknell because it handles temperature changes well and reduces leak risk through fewer joins. It works particularly well on larger flat roofs and modern extensions where a clean finish matters.
GRP Fibreglass Roofing
GRP creates a seamless finish that is ideal for dormers, garages, and smaller flat roofs where detail work around edges is key. Done properly, it is tough, neat, and low maintenance, but only if the base preparation and trims are spot on.
Torch-On Felt Roofing
Torch-on felt is a proven system and still one of the best value options when installed in the right layers with proper detailing. It is a great fit for many domestic flat roofs, especially when you want reliable performance without overcomplicating the build-up.
Liquid Roofing Systems
Liquid systems are useful when a roof has awkward shapes, lots of penetrations, or areas where a traditional membrane would need too many joins. Once cured, it forms a continuous waterproof layer that is ideal for refurbishments and complex roof layouts.
Why Flat Roof Problems Start in the Same Places?
Most flat roof issues in Bracknell show up at the edges, around outlets, and where water sits after rain. If those weak points are not detailed properly, even a “new” roof can fail early. We focus on drainage, trims, joins, and the condition of the deck underneath, because that is what stops call-backs.

Frequently Asked Questions
It depends on the material and how well it was installed. Many flat roofs last 20 to 40 years, and regular checks help catch minor defects before they turn into leaks.
Look for pooling water, splits or cracks, bubbling, loose edges, damp patches on ceilings, or leaks after heavy rain. If you notice any of these, it is worth getting it inspected sooner rather than later.
If the damage is limited and the structure is sound, a repair can be the right call. If the roof is failing across multiple areas or has been patched repeatedly, replacement is usually more cost-effective long term.
Yes. EPDM is durable, flexible, and often installed with fewer joins, which reduces weak points. It is a popular option for extensions, garages, and larger flat roofs.
