CrownPeak Roofing specialises in modern flat roof systems — EPDM rubber, GRP fibreglass, and high-performance felt — for garages, rear extensions, bay windows, dormers, and porches across Bracknell. We replace failing flat roofs with systems built to last decades, not years.
Why Bracknell's Flat Roofs Often Need Attention
A huge proportion of Bracknell's housing was built with single-storey garage extensions and rear additions that feature flat roofs. Many of these were covered in traditional three-layer bituminous felt during the 1960s–80s, which has a useful life of around 15–20 years. That means most original flat roofs in areas like Harmans Water, Wildridings, and Easthampstead have already exceeded their expected lifespan by decades.
Common signs of flat roof failure in Bracknell include: ponding water that takes more than 48 hours to evaporate after rain, visible blistering or cracking in the felt surface, damp patches appearing on the ceiling below, soft or spongy spots when walked on, and vegetation growing in accumulated debris. If you recognise any of these, your flat roof likely needs replacement rather than patching.

Flat Roof Repairs in Bracknell
Not every flat roof needs full replacement. If the deck structure is sound and damage is localised, we can carry out targeted repairs. For felt roofs, we patch blisters, reseal laps, and replace damaged sections. For EPDM and GRP roofs, we repair punctures, re-seal upstands, and fix detached edges. We always advise honestly about whether repair or replacement offers better long-term value for your specific situation.

A new flat roof in Bracknell typically costs between £1,432 and £3,057 depending on the size and system chosen. A single garage flat roof in EPDM starts from around £1,200, while a large rear extension in GRP might cost £2,500–£4,000. We provide free, detailed quotes for all Bracknell properties.
EPDM rubber and GRP fibreglass are both excellent choices for Bracknell's wet climate. EPDM is ideal for garages and simpler shapes — it handles temperature changes well and lasts 40–50 years. GRP is better for complex shapes, walkable areas, or where a premium finish is wanted, lasting 30+ years with minimal maintenance.
Modern flat roof systems last significantly longer than old-style felt. EPDM rubber roofs last 40–50 years, GRP fibreglass 30–40 years, and three-layer felt around 15–20 years. Many Bracknell properties still have original 1960s–70s felt that is well past its lifespan.
Yes, if the flat roof structure (deck boards) is sound, we can often overlay a new EPDM or GRP system on top of the existing surface. We can also patch-repair localised damage such as blisters, cracks, or failed seams. We assess whether repair or replacement offers better value during the free inspection.
Replacing a flat roof on an existing structure like a garage or extension usually falls under permitted development and does not need planning permission. If you're building a new extension with a flat roof, you may need permission from Bracknell Forest Council depending on the size and position.
Flat Roof Reviews
"Our garage flat roof had been leaking for years. CrownPeak fitted a new EPDM membrane in a single day. Two winters later, not a drop of water. Brilliant job and very reasonably priced."
"Had GRP fitted on our rear extension. The finish looks fantastic — smooth, clean, and completely watertight. The team explained the different options clearly and helped us choose the right system."
"Replaced old felt on our porch and bay window. The EPDM looks much neater and they assured us it'll last 40+ years. Good value compared to other quotes we got in Bracknell."
