Flat roofs need the right system and proper installation to last - a cheap job that fails in three years costs far more than doing it correctly the first time. We install and repair flat roofs across King's Lynn using EPDM rubber and GRP fibreglass systems with long-term guarantees.
Flat roofing is used on extensions, garage roofs, bay window canopies, and flat-roofed bungalows throughout King's Lynn. The area's combination of heavy winter rainfall and coastal winds puts flat roofs under real strain, so the choice of system and quality of installation matters considerably more than the headline price.
We install EPDM rubber roofing and GRP fibreglass (glass reinforced plastic) flat roofing systems. EPDM is a single-ply rubber membrane that is highly durable and handles ponding water well - it suits larger flat roof areas and carries a life expectancy of 40-50 years when correctly installed. GRP fibreglass creates a rigid, fully bonded surface that is ideal for smaller areas, complex shapes, and roofs with multiple upstands or penetrations. Both systems are installed onto new decking where required, with correct drainage falls formed to prevent water sitting. For repairs, we also work with torch-on felt systems that are already in place on existing roofs.
The most common flat roof failures we see in King's Lynn are poor drainage falls that let water pond and eventually find a way through, splitting where a membrane has been cut too short at an upstand, and failed detailing around rooflights. These are installation errors rather than material failures, which is why choosing an experienced team makes the difference between a roof that lasts decades and one that needs replacing in five years.
We survey your existing roof or new project, advise on the most appropriate system, and provide a written fixed-price quotation. Most residential flat roofs in King's Lynn are completed within one to three days. EPDM installations come with a 20-year manufacturer-backed warranty, and GRP systems carry a 25-year guarantee.
Flat roof installation in King's Lynn typically costs £70-£120 per square metre for EPDM or GRP, depending on access, deck condition, and roof complexity.
