Lime mortar required on flint cottages. The flat roofs on Rottingdean's extensions, garages and outbuildings require the right material specification for local conditions. We install GRP as our first choice in exposed positions. Victorian village (flint cottages, clay tile) plus 1930s-50s expansion (concrete tile)
Coastal cliff village, significant Channel exposure, conservation area in historic core Correct fall and drainage specification is critical in Rottingdean'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 Rottingdean 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 Rottingdean 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.

“A dormer flat roof letting water in on our place off High Street. They new warm-deck build-up, proper job. Straightforward and honest.”
“Called about blistered old felt over the kitchen. Stripped and re-laid, warm and dry now. Good communication throughout.”
“Had a leaking extension roof at our Rottingdean home. They recovered in EPDM rubber in a day, watertight — highly recommend.”
Flat roofs fail differently from pitched roofs — the signs are ponding, splits and lifting laps rather than slipped tiles. We see the same early signs again and again on Rottingdean roofs.
Tell-tale signs on a Rottingdean 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.
Brighton neighbourhood with Victorian village plus 1930s-50s expansion housing. The dominant roofing maintenance issue in Rottingdean: lime mortar for flint cottages and conservation area compliance.
Rottingdean's historic village core has flint cottages requiring lime mortar — cement causes irreversible damage to flint structures. The 1930s expansion has standard nail sickness issues. The same roofer needs to know both: lime mortar specification and concrete tile nail sickness assessment.
Every job follows the same clear process — no surprises, no hidden costs, full communication throughout.
We inspect the existing membrane, check drainage falls, assess the deck condition and identify any structural issues before quoting.
All existing felt or membrane stripped. Deck inspected thoroughly — any rot or saturation documented and quoted for before work proceeds.
Deck repaired or replaced where needed. Any drainage issues corrected. Falls assessed and improved where possible.
New membrane installed to manufacturer specification. GRP: full lamination across the entire deck as a single membrane. All upstands, outlets and penetrations correctly detailed.
10-year written workmanship guarantee issued. Free annual inspection for the first 5 years after installation.
Every Rottingdean roof is different, but these are the durations we quote most often:
| Job | Typical duration |
|---|---|
| Localised felt repair | 1–3 hours |
| Small extension / garage roof (GRP) | 1–2 days |
| EPDM rubber recover | 1–2 days |
| Warm-deck build-up (per roof) | 2–4 days |
| Full strip & re-lay | 2–4 days |
For Rottingdean jobs, 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.
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. That holds across most of Rottingdean. 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 Rottingdean, Rottingdean's flint and older village stock around The Green includes listed and conservation properties needing traditional, matched materials. Pavement scaffold and skip permits go through Brighton & Hove City Council; allow a few working days on streets like The Green, High Street, Nevill Road 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. 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 above the cliffs, Rottingdean takes direct coastal gales and salt spray that punish lead, flashing and mortar.
GRP fibreglass is our recommendation for most Rottingdean 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.
