Ridge mortar failure. The flat roofs on Hanover's extensions, garages and outbuildings require the right material specification for local conditions. We install GRP as our first choice in exposed positions. Victorian terraces (1870s-1890s), clay plain tile, shared valley lines
Hillside position with urban canyon wind funnelling from tightly-packed streets Correct fall and drainage specification is critical in Hanover'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 Hanover 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 Hanover 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 leaking extension roof on our place off Southover Street. They recovered in EPDM rubber in a day, watertight. Straightforward and honest.”
“Called about a dormer flat roof letting water in. New warm-deck build-up, proper job. Good communication throughout.”
“Had a split in the flat roof after winter at our Hanover home. They repaired quickly and neatly — highly recommend.”
In Hanover, 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 Hanover 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 (1870s-1890s) housing. The dominant roofing maintenance issue in Hanover: ridge mortar failure and shared valley lead disputes between terraces.
The dense Hanover terrace layout means shared valley lines between properties are the most frequent source of neighbour disputes. Identifying which property is responsible requires a roof-level survey from both sides.
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 Hanover 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 |
Around Hanover, 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 Hanover 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 Hanover, the steep, tightly-packed Victorian bye-law terraces off Southover Street mean rear access is difficult and permit-controlled pavement space is tight. Pavement scaffold and skip permits go through Brighton & Hove City Council; allow a few working days on streets like Southover Street, Islingword Road, Coleman Street where space is tight.

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, Hanover's hillside position catches wind-driven rain from the south-west, and the dense terracing funnels it along the streets.
GRP fibreglass is our recommendation for most Hanover 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.
