Flat Roofing in Peacehaven

Concrete tile at 80-100 years old is the dominant problem — carbonation means tiles crumble at the edges and nibs. The flat roofs on Peacehaven's extensions, garages and outbuildings require the right material specification for local conditions. We install GRP as our first choice in exposed positions.

Flat Roof Drainage in Peacehaven — Getting It Right

Cliff-top grid town with no natural shelter from south or south-west. The grid street layout creates wind tunnelling — south-facing gardens and roof slopes receive full Channel blast. Temperature extremes are higher than sheltered valley towns: hot in summer heat, exposed in winter gales. Correct fall and drainage specification is critical in Peacehaven'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.

Deck Inspection — What We Find Under the Old Roof

We always strip to the deck before installation. Common findings on Peacehaven 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.

Maintenance for Peacehaven Flat Roofs

A GRP flat roof in Peacehaven 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.

Customer Reviews

What Peacehaven Homeowners Say

★★★★★

“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.”

Janet B. · Telscombe Road, Peacehaven

★★★★★

“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.”

Colin H. · South Coast Road, Peacehaven

★★★★★

“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.”

Pat E. · Arundel Road, Peacehaven

Honest advice

How to Tell You Need Flat Roofing

In Peacehaven, 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.

What to look for:

Pooling water that sits for days after rain (ponding)
Cracks, splits or blisters in felt, or lifting laps at the joints
A damp patch on the ceiling directly below a flat roof or extension
Green algae and a tired, chalky surface on older felt
Felt at or past 15–20 years — near the end of its life

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.

Local Knowledge

What Makes Peacehaven Different

The Housing Stock

Grid-pattern inter-war planned town from the 1920s. Uniform semi-detached and detached properties with concrete tile now 70-100 years old. Concrete interlocking tile at 80-100 years old showing widespread carbonation and nail sickness. The combination of both failure modes simultaneously is unique to this era of stock..

Climate and Exposure

Cliff-top grid town with no natural shelter. Grid street layout creates wind tunnelling. Maximum Channel exposure on south-facing slopes..

The Key Issue in Peacehaven

Concrete tile at 80-100 years old is beyond the design life of the material. Carbonation means tiles crumble at the edges. Many Peacehaven roofs are held together only by ridge and hip mortar..

Pricing note: For Peacehaven properties built before 1950, re-roofing is almost always more cost-effective than repair over any 10-year horizon..

How It Works

Our Flat Roofing Process in Peacehaven

Every job follows the same clear process — no surprises, no hidden costs, full communication throughout.

Free Flat Roof Survey

We inspect the existing membrane, check drainage falls, assess the deck condition and identify any structural issues before quoting.

Strip to Deck

All existing felt or membrane stripped. Deck inspected thoroughly — any rot or saturation documented and quoted for before work proceeds.

Deck Preparation

Deck repaired or replaced where needed. Any drainage issues corrected. Falls assessed and improved where possible.

GRP or EPDM Installation

New membrane installed to manufacturer specification. GRP: full lamination across the entire deck as a single membrane. All upstands, outlets and penetrations correctly detailed.

Completion and Guarantee

10-year written workmanship guarantee issued. Free annual inspection for the first 5 years after installation.

Timescales

How Long Does It Take?

Every Peacehaven 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 Peacehaven 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.

Access

Scaffold, Skips & Street Access in Peacehaven

On Peacehaven 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 Peacehaven, Peacehaven's 1920s–30s bungalows and post-war houses off the South Coast Road sit on open cliff-top plots with easy access. Pavement scaffold and skip permits go through Lewes District Council; allow a few working days on streets like South Coast Road, Roderick Avenue, Steyning Avenue where space is tight.

Guarantee

The Guarantee in Plain Terms

Every Peacehaven job we complete is backed in writing: our workmanship is backed by a written 10-year guarantee, with manufacturer warranties on materials on top.

Covered: our workmanship for 10 years, in writing, and transferable if you sell.
On top: manufacturer warranties on materials (terms vary by product).
Not covered: storm or impact damage — that is an insurance matter, which we document for your claim.

A covered fault means we return and fix it at our cost — that is what the guarantee is for.

Good to know

What It Is Like While We Work

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, on an exposed cliff-top plateau, Peacehaven takes some of the most direct wind and salt exposure on the Sussex coast.

FAQ

Flat Roofing Peacehaven — Frequently Asked Questions

GRP fibreglass is our recommendation for most Peacehaven 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.
