📞 Call Now: 01473 807630Claydon's 1970s–90s rear extensions carry flat roofs approaching or past their design life. The Gipping valley damp makes felt degrade faster than on drier ground — GRP fibreglass is a particularly strong investment in this setting. Seamless construction eliminates the joints that degrade fastest in damp conditions, with 25-year performance. We survey free, check deck condition, and include replacement where needed.

📞 01473 807630"GRP flat roof on rear extension — two days, professional job. Deck softened section replaced at no extra cost."
"Garage flat roof in EPDM. One-day job, very tidy."
"Extension flat roof replaced. Correct junction detailing. Would recommend."
A flat roof that's failing announces itself with pooling water, blisters, splits or internal damp below. On Ipswich extensions and garages, these are the signs it needs attention rather than another patch.
When it is not the answer: If the membrane is sound and only a lap or upstand has lifted, a localised repair is the right fix — you don't need a full re-cover, and we won't sell you one. Read the full guide.
Flat roofs turn up all over Ipswich — the rear kitchen extensions on the suburban stock, the ageing felt garages across the estates, the dockside and waterfront flats that take the full weather off the Orwell, and the flat-roofed dormers on loft conversions. Each calls for a different answer. Small suburban extensions suit seamless GRP; larger, simpler spans suit EPDM; and the exposed waterfront roofs need robust perimeter fixing and proper falls whichever system goes on. The one detail that decides whether a flat roof lasts its full life or fails early is drainage — a flat roof is never truly flat, and an under-falled roof that ponds water is the fastest route to membrane failure in Ipswich's wet autumns.
System choice on an Ipswich flat roof comes down to size, shape and exposure. GRP fibreglass is laid wet and cured to a single seamless surface with no joints to fail — ideal for the rear extensions and garages that make up most of the local work, with a design life beyond 25 years. EPDM rubber suits larger, simpler spans and the exposed dockside roofs where a single sheet performs well. Modern torch-on felt is the budget option, a genuine improvement on the old pour-and-roll felt but shorter-lived. Whichever system goes on, we build in adequate falls to Building Regulations and, where more than half the roof is replaced, upgrade the insulation to current standards — a warm-deck build-up on the many Ipswich extensions with a habitable room below.
We assess the deck, the falls, the upstands and the current covering to recommend GRP, EPDM or felt for your specific roof and its exposure.
A fixed price for the system chosen, with any deck repair and insulation upgrade separated out and explained.
We book a run of dry days for GRP; EPDM and felt can go on year-round.
We strip the old covering, repair or replace the deck, build in proper falls, and lay the new system with dressed upstands and trims.
Site cleared, waste removed, and the guarantee handed over in writing.
| Job | Typical duration |
|---|---|
| Single garage re-cover | 1–2 days |
| Small rear extension (8–20 m²) | 2–3 days |
| Larger extension flat roof | 3–5 days |
| Flat-roofed dormer re-cover | 1–2 days |
GRP needs dry, warmer conditions to cure — we schedule around Suffolk's cold snaps and wet spells.
Most Ipswich flat roofs are single-storey and reached from a tower or ladder; scaffold is quoted only where the flat roof is at height or over an awkward drop. Scaffold is specified for: flat roofs at first-floor level, dormers, and anything over a difficult access point - always itemised in your written quote, never a hidden extra, and we arrange it.
Claydon's 1970s–90s housing along the A14 corridor north of Ipswich is producing regular ridge and hip mortar failures as it ages, with concrete interlocking tile the dominant covering. Pavement scaffold and skip permits go through Mid Suffolk District Council; allow a few working days on streets like Church Lane, the Norwich Road frontage, Barham approach where space is tight.

Covering IP6 and surrounding postcodes.
The flat roof system carries a written 10-year workmanship guarantee; GRP and EPDM membranes carry manufacturer warranties of 20–25 years on top.
If a fault appears in covered work, we come back and put it right. No quibbling, no re-charge.
Flat roof work is low-disruption — a little noise during strip-out and the smell of resin on a GRP day, which clears quickly. You don't need to be home for external work. You do not need to stay home for external work - we just need power and access agreed in advance.
EPDM and felt fit year-round; GRP waits for dry conditions. If rain interrupts, we make the deck watertight before we leave. Set on the higher ground above the Gipping, Claydon's roofs catch the wind funnelling down the valley corridor, which lifts poorly-bedded ridge tiles and dry-verge caps.
A standard rear extension costs £1,000–£2,200 in GRP. Free survey, exact quote.
