Flat roofs on extensions, garages, and outbuildings across Haverhill need the right system to perform long-term. We install EPDM rubber and GRP fibreglass flat roofs that carry a 20-year guarantee and require far less maintenance than traditional felt.

Flat roofing covers a large proportion of the single-storey extensions and garages in Haverhill, and most problems we see are on ageing three-layer felt systems that were never designed to last more than 15 years. If your flat roof is blistering, cracking, or holding standing water, the underlying deck or falls may also need attention — and that is a job for a proper flat roofing specialist, not a temporary patch.
We install two main systems. GRP fibreglass roofing is laminated in-situ and suits roofs with straightforward geometry — it forms a completely seamless membrane with no joints for water to penetrate. EPDM rubber roofing suits larger areas and roofs with more complex shapes; it is extremely durable, UV-stable, and performs well in the temperature variations we see in East Anglia. Both systems are installed over a new OSB or plywood deck where the existing decking has deteriorated. We also address the falls at this stage — flat roofs should drain at a minimum of 1:80, and many older roofs in this area were laid too flat, which is why they pond water. Upstands, drip edges, and outlets are all formed correctly as part of the installation.
Getting flat roofing wrong creates significant damage quickly. Water sitting on a flat roof that has insufficient falls or poorly formed upstands will find a way in within months. A professionally installed modern membrane lasts two to three times longer than traditional felt and requires only an occasional inspection rather than regular maintenance.
We survey flat roofs free of charge and provide a written quotation within two working days. Most residential flat roofs in Haverhill are completed in one to two days. Both GRP and EPDM installations carry a 20-year manufacturer-backed guarantee.
Flat roofs in Haverhill typically cost between £70 and £110 per square metre for a full GRP or EPDM installation, including new decking where required.
