Tell us the job in 30 seconds. No pushy sales, no call-out fee.
Nail sickness at near-universal levels on pre-1960 stock — most concrete tiles are now held by gravity only. The flat roofs on Saltdean's extensions, garages and outbuildings require the right material specification for local conditions. We install GRP as our first choice in exposed positions.
Cliff-top position gives maximum Channel exposure — among the most exposed residential locations in East Sussex. Salt deposition significantly higher than even Brighton seafront due to elevation and exposure angle. Prevailing south-westerly hits cliff face and is deflected upward, increasing wind loading on roof surfaces. Correct fall and drainage specification is critical in Saltdean's rainfall pattern. We survey the existing structure, assess drainage routes, and specify falls that clear the roof surface within 24 hours of rainfall stopping.
We always strip to the deck before installation. Common findings on Saltdean properties: saturated OSB or plywood deck from years of felt failure; joist rot from sustained moisture; inadequate insulation. We document all findings before quoting for extra work — never proceed without your agreement.
A GRP flat roof in Saltdean requires minimal maintenance — an annual inspection and clearing of any debris from outlets. EPDM requires lap joint inspection every 2-3 years in East Sussex conditions. We carry out free annual inspections for all flat roofing customers for the first 5 years after installation.

“Old felt roof on the extension had been leaking for two years. GRP installed in a day and a half. Looks completely different and I have no doubt it will outlast everything else on the property.”
“Replaced the garage felt with GRP. Quick, tidy and they found some deck rot I wasn't aware of — fixed it and showed me before proceeding. Honest job.”
“Third flat roof replacement in 30 years on the same extension. Went with GRP this time on their advice. Should be the last time I ever need to do it.”
In Saltdean, most flat roofing jobs announce themselves before you ever get on the roof. Flat roofs fail differently from pitched roofs — the signs are ponding, splits and lifting laps rather than slipped tiles.
Tell-tale signs on a Saltdean roof:
When it is not the answer: If a GRP or EPDM roof is only 10 years old with a single split, a localised repair is usually right — replacement would be premature — see our guide.
Inter-war 1930s-50s cliff-top development. Semi-detached and detached properties on Arundel Drive and Saltdean Oval with concrete tile now 70-90 years old. Concrete interlocking tile at 70-90 years old — well beyond design life. Lead flashing corrodes 40% faster than inland due to cliff-top salt exposure..
Cliff-top position gives maximum Channel exposure. Salt deposition significantly higher than Brighton seafront. Prevailing south-westerly deflected upward by the cliff face..
Nail sickness is at near-universal levels on Saltdean's pre-1960 stock. Most concrete tiles are now held only by gravity. Any significant south-westerly risks cascade displacement..
Pricing note: Most Saltdean properties built before 1960 are at or past the point where re-roofing is more cost-effective than repair..

Around Saltdean, gRP and warm-deck systems need dry, mild conditions to cure — we book them into settled windows and never lay resin onto a wet deck.
On Saltdean roofs, most flat roofs are reached from a tower or ladder; scaffold is needed only where the roof is at height or edge protection is required. Scaffold is specified for first-floor or higher flat roofs, and anywhere an exposed edge needs protection — always itemised in your written quote, never a hidden extra, and we arrange it.
In Saltdean, Saltdean's 1930s and post-war houses off Longridge Avenue carry concrete tile now often at end of life, with generous access on suburban plots. Pavement scaffold and skip permits go through Brighton & Hove City Council; allow a few working days on streets like Longridge Avenue, Saltdean Vale, Chiltington Way where space is tight.

Usually a quiet one- to two-day job over an extension or garage — minimal mess, and we clear the old covering as we go. It is a routine sight on Saltdean streets. You do not need to stay home for external work — we just need power and access agreed in advance.
Felt and EPDM can be laid in cooler weather; GRP needs mild, dry conditions to cure, so we plan resin work around the forecast. Locally, perched on the cliff-top, Saltdean takes some of the most direct coastal exposure in the area — salt spray and gales hit roofs hard.
GRP fibreglass is our recommendation for most Saltdean properties. It forms a seamless, jointless membrane with no lap joints to fail, resists UV well, and has an expected life of 30-40 years. EPDM is suitable for sheltered positions. Traditional felt is not recommended for East Sussex conditions.
GRP fibreglass is £70-90 per sqm installed. A typical kitchen extension (20-25 sqm) costs £1,400-£2,250. A double garage (40 sqm) costs £2,800-£3,600. All prices include stripping the old felt and debris disposal.
GRP fibreglass correctly installed lasts 30-40 years in East Sussex conditions. EPDM lasts 20-30 years. Traditional felt lasts 8-12 years. The significant lifespan difference justifies the higher upfront cost of GRP for most customers.
Replacing a flat roof with the same material and specification is permitted development. Changing the roof type (e.g. adding a raised parapet or changing the drainage system significantly) may require planning approval. We advise on this during the free survey.
Yes — this is the most common flat roofing job we carry out. We strip all existing felt, inspect and repair the deck if needed, and install a GRP system directly over the existing structure in most cases.
10-year written workmanship guarantee on all GRP and EPDM installations. The GRP material itself carries a manufacturer guarantee of 25 years.
