We stand by every deck we lay, and our 20 to 40-year guarantees mean you wil

How We Built Our Reputation
London GRP Roofing Ltd was established with a clear goal: to replace outdated, leak-prone flat roofing materials with a modern alternative that genuinely lasts. Traditional felt and bitumen had served their time, but property owners needed something tougher against heavy rain and freeze-thaw cycles. By specializing in Glass Reinforced Plastic, we mastered a seamless, cold-applied membrane system that forms a continuous, joint-free barrier. Over the past 15 years, our team has completed hundreds of installations across London and Kent, earning a reputation for reliability among private homeowners, builders, and commercial clients. Today, we continue to operate as a tight-knit family business where quality control comes first. Whether we are installing a warm roof insulation buildup on a domestic extension or surfacing a heavy-traffic commercial balcony, every square metre receives the same meticulous attention to detail.
