About Us
Over 25 Years of Flat Roofing Excellence in London
Grp Flat Roofing has spent over 25 years building a reputation across Greater London, Surrey, Kent, and Essex for uncompromising quality. We started with a clear objective: to offer the highest quality flat roofing products at realistic prices with genuinely reliable customer service. Today, our specialist team works closely with homeowners, architects, and conservation officers to deliver GRP fibreglass and EPDM rubber roofing systems built to last. We use Lloyds approved materials and strict quality control on every job, ensuring your property stays watertight and secure for decades.
Quality Workmanship
We started Grp Flat Roofing because we were tired of seeing homeowners let down by cheap felt roofs that failed after just a few years. A flat roof should be the last thing on your mind, not a constant source of leaks and worry. That is why we refuse to cut corners, whether that means applying the correct thickness of fibreglass matting or ensuring every EPDM seam is perfectly sealed. When my team finishes a job on your property, it has to be spot-on, durable, and completely watertight. We stand

How We Became London's Trusted Flat Roofing Specialists
When we entered the roofing industry over two decades ago, traditional felt roofs were failing property owners across London. Extension roofs, garages, and porches were constantly letting water in due to seams coming apart under thermal movement. We saw the need for a permanent alternative. By pioneering the installation of seamless GRP fibreglass and advanced EPDM rubber membranes, we transformed how flat roofs perform against British weather. Unlike felt, these modern systems encapsulate the roof surface into a single watertight barrier that resists UV rays and extreme temperatures. Over the last 25 years, our team has completed hundreds of domestic and commercial projects from Brondesbury Park to Kingston upon Thames. We maintain our founding standard: uncompromising craftsmanship, meticulous attention to detail, and work that outlasts traditional alternatives.
