📞 Call Now: 01473 807630Stowmarket's housing spans Victorian terraces through to 1970s–90s development. Victorian and Edwardian properties have rear outrigger extensions and bay window roofs often at or past their design life. Post-war and 1970s properties have rear extension flat roofs that may have been replaced once already and need attention again. GRP fibreglass on a new deck is our standard specification — seamless, 25-year performance.

📞 01473 807630"Rear extension flat roof — old felt completely failed. New GRP on fresh deck, two days. Dry ceiling for the first time in years."
"Garage flat roof in GRP. Good price, professional job, tidy."
"Bay window flat roof replaced. Correct detailing at the wall junction."
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.
Stowmarket mixes Victorian terraces near the centre with newer estate housing on the edges, so access ranges from permit-controlled to open-frontage. Pavement scaffold and skip permits go through Mid Suffolk District Council; allow a few working days on streets like Ipswich Street, Tavern Street, the town-centre lanes where space is tight.
Stowmarket mixes Victorian terraces near the centre with substantial newer estate development on the edges, so the roofing picture spans everything from lime-mortar chimney stacks and shared valleys to modern concrete-tile roofs reaching middle age. The Gipping valley position brings frost pockets through the winter that accelerate the freeze-thaw cracking of ridge and verge mortar. Whether your property is a town-centre terrace needing period detailing or an estate house due its first re-roof, we match the specification to the age and construction rather than applying a one-size approach.

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. Inland mid-Suffolk position sees frost pockets in the Gipping valley through winter.
A standard rear extension in Stowmarket costs £1,100–£2,400 in GRP. Free survey, exact quote.
