Flat Roofing
Modern fibreglass, EPDM rubber, and felt flat roofing systems for extensions, garages, and commercial properties.
About This Service
Modern flat roofing systems are far more durable and long-lasting than the old felt that gave flat roofs a bad reputation. West Sussex Roofing install and repair all leading flat roofing systems across London and West Sussex. Our preferred specification for most residential flat roofs is fibreglass GRP — a seamless, rigid surface with a 25-year life expectancy that resists UV, ponding water, foot traffic, and root intrusion. Where flexibility is required we install EPDM rubber membrane, the market-leading commercial flat roof system trusted on buildings worldwide. We also carry out like-for-like felt replacements for heritage properties and temporary structures. Every flat roof installation includes proper drainage design, correct fall configuration, and perimeter edge detailing to the highest waterproofing standard.
