GRP fibreglass and EPDM flat roofing specialists in Stanley, Chippenham. Extension and garage flat roof replacement. Free no-obligation surveys.
In short: Flat Roofing in Stanley, Chippenham: Flat roofing runs £900–£2,500 for a typical extension. We cover Stanley (SN15) with free quotes, no call-out fee and a 10-year guarantee. Failing felt flat roofs are best replaced in GRP or EPDM rather than patched.
Flat roofing calls from Stanley are primarily original felt flat roofs on 1970s rear extensions, now at end-of-life, and occasional garage roofs from the same era. We replace felt flat roofs with GRP fibreglass as standard — same cost bracket, 25-year material guarantee, seamless. Stanley is 2 miles from our base — free flat roof surveys throughout the area.
Stanley is one of Chippenham's largest post-war estates, built primarily 1958–1978 with concrete interlocking tile throughout. It is the most concentrated nail sickness zone in our coverage area. Original mild steel fixing nails on these properties are now 55–65 years old — corroded through and leaving tiles resting on the batten rather than being actively fixed. Tiles displace progressively in moderate wind, and the pattern of failure is across whole slopes rather than isolated tiles.

Stanley sits on the northern edge of Chippenham with moderate exposure. The defining characteristic is not climate but age: the entire estate was built in a single phase, meaning every property's roof is at the same maintenance stage simultaneously.
Large post-war estate built primarily 1958–1978 with concrete interlocking tile throughout. The most concentrated nail sickness zone in our coverage — original mild steel fixing nails are now 55–65 years old and corroded through on most properties.
Nail sickness presenting as regular tile displacement across all slopes is the defining call from Stanley. Individual tile re-fixing is a temporary measure that doesn't resolve the systemic nail failure — only re-roofing does.
We carry out more nail sickness surveys on Stanley than any other Chippenham area. The assessment is almost always the same: systemic fixing failure, full or phased re-roof recommended. We quote both options side by side.
GRP fibreglass is our standard recommendation for flat roof replacement across all Chippenham neighbourhoods — same cost bracket as re-felting, 25-year material guarantee, and no joints to fail. The deck inspection we carry out on every strip identifies any rotten boards before the new membrane is applied. Drainage fall correction is included as standard — ponding flat roofs were often built with insufficient falls and the membrane replacement alone doesn't resolve the underlying drainage issue. Where the existing felt is more than 25 years old, the boards beneath are always inspected before any new membrane is specified.
We carry GRP materials for neighbourhood emergency visits — same-day temporary seal is available when a full replacement needs scheduling. For properties in high-moisture areas of Chippenham, GRP is particularly well suited: it's seamless, UV stable, and handles the moisture environment significantly better than standard felt.

01249 247 076 ✉ Email UsStanley is a Chippenham district of predominantly 1958–78 concrete-interlocking-tile housing on the eastern side of town. On this kind of stock, the problems we see most in Stanley are widespread nail sickness across the 1958–78 concrete-tile roofs, dropped ridge and verge mortar, and failed felt underlay. Stanley sits on the eastern side of Chippenham toward the Avon and Calne road.
We remove the old covering and inspect the deck for rot — the step most quotes skip.
We check and correct drainage falls so water runs off cleanly rather than ponding.
A fixed price covering deck repairs, membrane and trims, agreed before work starts.
GRP is laid wet and cures seamless; EPDM is bonded as one sheet. Trims and upstands dressed in.
The finished roof carries a 25-year material guarantee (GRP) plus our workmanship cover.
| Job | Typical duration |
|---|---|
| Small extension (GRP, up to 15m²) | 1–2 days |
| Standard extension (GRP) | 2–3 days |
| Garage roof (EPDM) | 1 day |
| Deck / board replacement | +half to full day |
| Larger / commercial flat roof | per assessment |
GRP needs dry conditions to cure; we won't lay fibreglass in rain, so winter jobs are weather-scheduled.
Stanley is post-war estate housing with generous driveway and side access, ideal for scaffold and skip placement. Scaffold and skip permits go through Wiltshire Council, and on the estate roads off the Calne road we allow extra time for setup. Access is always itemised in your written quote, never a hidden extra.
GRP carries a 25-year material guarantee and EPDM 20 years; our workmanship cover sits on top, and the deck and falls — which decide longevity — are guaranteed too.
