📞 Call Now: 0172 223 9611Flat roofing in Gillingham covers extensions, garages, bay roofs and outbuildings across the area's Victorian and Edwardian town centre, 1930s–70s mixed estates. Given clay vale humidity from Stour Valley; riverside tree debris into gutters, we recommend GRP fibreglass as the primary system for most Gillingham properties — its seamless laminate surface handles the local conditions better than felt, with a 25-year guarantee and 30–40 year realistic lifespan.
We cover Gillingham and all surrounding SP8 villages for flat roofing installation and replacement. Free surveys, fixed-price quotes.
Given Stour Valley, sheltered and clay vale humidity from Stour Valley; riverside tree debris into gutters, GRP fibreglass is our standard recommendation for Gillingham. EPDM rubber is an alternative for larger areas above approximately 80m². We do not install new built-up felt as a permanent flat roofing solution — its 10–15 year design life is too short for the conditions in this area.
| System | Per m² | 25m² extension | Lifespan |
|---|---|---|---|
| GRP Fibreglass | £70–£100 | £1,750–£2,500 | 25–40 years |
| EPDM Rubber | £60–£90 | £1,500–£2,250 | 25–35 years |
| Felt (replacement only) | £40–£65 | £1,000–£1,625 | 10–15 years |
Regardless of system, correct fall to outlet (minimum 1:80), proper upstand height (minimum 150mm) and sound deck preparation are essential. On Gillingham's older extension stock, deck inspection before installation often reveals water-damaged boarding that must be replaced — we include this in our quoted price, not as a surprise add-on.

📞 0172 223 9611Flat roofs fail differently to pitched ones — the signs are ponding, splits and blistering rather than slipped tiles.
When it is not the answer: If the membrane is sound and only a flashing or upstand has failed, a localised repair beats a full recover — we'll tell you which you need. Read the full guide.
We check the deck, falls, upstands and outlets, and establish whether it's a repair or a recover.
Itemised quote specifying the system — EPDM rubber, GRP fibreglass or high-performance felt — and the price.
Booked around a dry window; flat-roof systems need dry conditions to bond.
We strip the failed covering, correct the falls and insulation where needed, and lay the new membrane with dressed edges and outlets.
Site cleared, outlets tested, and the guarantee handed over.

| Small flat roof repair | 2–4 hours |
| Garage or extension recover | 1–2 days |
