Flat Roofing in Crawley
Flat roof replacement covers stripping an existing flat roof back to the deck and re-covering it with a modern waterproof system — EPDM rubber membrane, GRP fibreglass or traditional felt — chosen according to the roof's size, detailing and expected lifespan.
In Crawley, that covers Ifield, Three Bridges, Southgate, Furnace Green, Broadfield, Pound Hill, Maidenbower, Northgate, West Green, Langley Green, Tilgate, Gossops Green, Bewbush. Crawley combines postwar new-town neighbourhoods with older pockets around Ifield, Three Bridges and Southgate, and sits close to Gatwick Airport with strong transport links into London and along the M23. Housing stock ranges from 1950s–70s estate homes to Victorian terraces and more recent developments, which means project requirements vary considerably from one street to the next.

Property styles in Crawley
Crawley's housing mix includes postwar semis and terraces across the New Town neighbourhoods, Victorian and Edwardian houses around the older Ifield and Southgate areas, and newer estate housing on the town's edges. Many properties are well suited to rear or side-return extensions where garden depth allows, and loft conversions are common in the older stock.
Planning considerations
Crawley Borough Council is the local planning authority. Ifield village and parts of the old town centre fall within conservation areas, which affects permitted development rights and materials on visible elevations. Properties near Gatwick Airport may also be subject to safeguarding or noise-related planning considerations, which we check at feasibility stage.

FAQs
Flat Roofing in Crawley: FAQs
Do you provide flat roofing across all of Crawley?
Yes, we cover the RH10 and RH11 postcode areas in full, including Ifield, Three Bridges, Southgate, Furnace Green, Broadfield, Pound Hill, Maidenbower, Northgate, West Green, Langley Green, Tilgate, Gossops Green, Bewbush.
Which flat roof system should I choose — EPDM, GRP or felt?
EPDM offers a long lifespan with a single membrane and few joints, suiting most domestic flat roofs; GRP suits roofs with complex upstands and detailing since it's laid and cured seamlessly in situ; felt is the lowest-cost option but has the shortest expected lifespan. We advise on the right system for your roof and budget at survey.
Why does my flat roof have ponding water?
Ponding usually means the roof's falls — the slight slope that directs water to an outlet — are insufficient or have settled over time. We assess and correct falls as part of re-covering rather than simply laying a new membrane over the same problem.
Do you cover both RH10 and RH11 in Crawley?
Yes, we work across both postcode areas, including the town centre, Ifield, Three Bridges, Southgate, Furnace Green and the surrounding neighbourhoods.
