We design and install flat roofs on extensions, garages, and outbuildings across Newmarket using modern GRP fibreglass and EPDM rubber systems. Modern flat roofing materials outlast traditional felt by decades and carry long manufacturer warranties. We also repair and overlay existing flat roofs that are leaking or deteriorating.

Flat roofing covers extensions, single-storey additions, bay windows, garages, and outbuildings across Newmarket. Traditional mineral felt flat roofs have a lifespan of around 10 to 15 years, and many properties in the area still carry these older systems. When they fail, the choice is between a like-for-like felt overlay — a short-term fix — or upgrading to a modern GRP fibreglass or EPDM rubber membrane, both of which offer far greater longevity.
GRP fibreglass roofing is applied as a liquid that cures to form a single seamless surface with no joints for water to penetrate. We apply it over a marine-grade plywood deck, finish with a protective topcoat, and trim all edges with GRP trims. EPDM rubber is an alternative where a large, single-piece membrane is bonded to the deck — it's highly flexible and performs well through temperature extremes. Both systems require correct detailing at upstands, outlets, and abutments with walls and fascias, which is where most flat roof failures occur.
A poorly installed flat roof will pond, crack at the edges, or delaminate within a few years. The cost of a water-damaged ceiling, soaked insulation, and structural timber repair far exceeds the saving made by using cheap materials or inexperienced labour. GRP and EPDM systems installed correctly should last 25 years or more.
We survey existing flat roofs free of charge and advise whether repair, overlay, or full replacement is the right approach. New installations are typically completed in one to three days depending on size. All our flat roofing work carries a minimum ten-year guarantee.
Flat roof installation in Newmarket using GRP fibreglass typically costs between £70 and £110 per square metre, including all materials, decking, and trims.
