Flat Roofing in Horsham
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 West Sussex. Our preferred specification for most residential flat roofs is fibreglass GRP — a seamless, rigid surface built to resist 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.
About Horsham
Horsham is a thriving market town with a mix of historic properties in the town centre and substantial residential development in the surrounding villages. We serve homeowners throughout Horsham, Southwater, Roffey, Broadbridge Heath, and the surrounding West Sussex villages. Rural West Sussex properties often feature natural Horsham stone roofs — a traditional local material that requires specialist knowledge to repair correctly. Our team has experience working with Horsham stone as well as all modern tile and slate specifications. Larger detached houses in the villages around Horsham also tend to have complex roofs with multiple pitches, dormers, and chimney stacks that benefit from our specialist expertise.
