Bognor Regis presents two distinct roofing challenges: the Edwardian seafront terraces of Marine Drive and Aldwick Road need period-appropriate materials and conservation awareness, while the post-war estates in Bersted and Rose Green have nail-sick concrete tile roofs now reaching the end of their design life.

GRP fibreglass is the primary recommendation for flat roofs in Bognor Regis. The combination of coastal UV and salt aerosol degrades felt within 8 years at most. GRP's gelcoat resists both. EPDM is appropriate for large areas. Marine-grade sealant is used on all joints.
Flat roofing work in Bognor Regis covers bungalow extensions and garage roofs throughout Aldwick and Felpham, where GRP is standard specification. All flat roof work is surveyed before quoting — falls, drainage points, upstand details and any existing structural issues are assessed as part of the free survey.

📞 01243 278085GRP fibreglass provides the longest lifespan and the most seamless finish; it is our default recommendation for most Bognor Regis properties. EPDM rubber is cost-effective for larger areas and equally durable. Felt is not recommended for any Bognor Regis property — the lifespan is too short to justify the cost, in Bognor Regis's salt air and UV environment.
"Garage flat roof was leaking after only twelve years on the old felt. GRP conversion — not a drop since. Should have done it years ago."
"Extension flat roof done in GRP. Neat finish, no mess left. They explained every step of the process before starting."
"Had EPDM on the large back extension. Brilliant product, very professional installation. Highly recommend."
Bognor regis is the most exposed coastal town in our coverage area — the seafront and the residential streets behind the promenade face direct solent weather with minimal shelter. For flat roofing in Bognor Regis this means galvanised nail fixings corrode faster here than anywhere else we cover — nail sickness on Bognor seafront properties appears 5 to 10 years earlier than equivalent inland properties. The mix of edwardian seafront terraces, 1930s semis and post-war residential behind the town centre covers every roofing era, with the seafront properties facing the most aggressive salt air exposure. We specify stainless fixings as standard on all bognor re-roofing and use patination oil on all lead work as a baseline, not an upgrade.

A typical garage flat roof in Bognor Regis costs £800–£1,500. A rear extension flat roof is typically £1,600–£4,500 depending on size and system. We quote by the square metre after a free survey.
GRP fibreglass lasts 25 to 40 years in Bognor Regis's conditions. EPDM rubber lasts 30 to 50 years. Traditional felt lasts 8 to 12 years at most in Bognor Regis's salt air and UV environment — we do not recommend felt replacement for any Bognor Regis property.
Yes — felt to GRP conversion is a standard job for us. We remove the existing felt and boarding, install new treated decking, apply the GRP system and finish with a UV-stable coloured gelcoat. The improvement in lifespan is significant and the upfront cost difference is recovered within a few years.
Blistering, cracking, pooling water after rain, or felt that has become soft and spongy to walk on are all signs a replacement is needed rather than a patch repair. If a felt flat roof is over 12 years old in Bognor Regis's coastal climate and showing any of these signs, replacement with GRP or EPDM is almost always the more cost-effective long-term decision.
Replacing a flat roof like-for-like on a house extension or outbuilding is generally permitted development in Bognor Regis. Changing the height or footprint, or work on a listed building or in a conservation area, may require consent. We advise at the survey stage.
Correct drainage is the single most important factor in flat roof longevity. All our flat roof installations include assessment of falls, outlet positioning and gutter connections before work starts. We correct any drainage deficiencies as part of the installation — a new flat roof laid to inadequate falls will fail early regardless of the material quality.
Every flat roof survey covers: the existing deck condition (whether the existing decking boards are sound or require replacement), the current falls (whether adequate drainage exists or whether tapered insulation is needed to correct the falls), the upstand heights (whether the covering can be taken up to the required minimum height at edges and abutments), and the outlet position and sizing. In Bognor Regis, where direct Solent exposure and salt aerosol at the UK coast, we also assess whether coastal UV intensity or harbour moisture exposure affects the system recommendation. A flat roof that drains correctly and has proper upstand details lasts decades longer than one where these fundamentals were not addressed at installation.
GRP fibreglass is applied as a liquid laminate that cures to a rigid seamless surface. We apply two layers of chopped strand mat saturated with resin, followed by the coloured gelcoat finish. The entire surface is seamless — no joints to open, no laps to fail. Upstands are formed to the correct height and radius at all edges. Outlets are GRP-lined. The gelcoat provides UV protection that significantly outlasts felt surface treatment in Chichester's coastal UV environment. Installation requires temperatures above 5°C — we plan flat roof work around weather forecasts to ensure the correct curing conditions.
A standard single-car garage flat roof in GRP typically costs £900 to £1,800 in Bognor Regis. Rear extension flat roofs up to 25m² cost £1,800 to £4,000. Larger areas of 25 to 60m² run £3,500 to £7,500. These prices include deck inspection, any necessary deck replacement, falls correction where needed, full GRP lamination and gelcoat finish. EPDM rubber costs approximately 10 to 15 per cent less than GRP on the same area with comparable performance over the long term.
