Cocklebury sits between the heavily nail-sick Hardenhuish stock and the flat roof-dominated Pewsham estate, sharing characteristics of both. 1970s properties are entering the early nail sickness phase — tiles loosening but not yet displacing at the Hardenhuish rate. 1980s additions have flat roofs and UPVC guttering now 40–45 years old. The combination makes Cocklebury a high-activity maintenance area where survey work regularly identifies multiple issues on the same property.

Cocklebury sits between central Chippenham and the Pewsham development, with moderate exposure. The 1970s and 1980s housing creates a maintenance profile that bridges the nail sickness era and the flat roof era.
1970s properties are entering the early nail sickness phase — still at the optimal intervention window where phased re-roofing is cost-effective. 1980s additions have flat roofs and UPVC guttering now 40–45 years old.
Early nail sickness on 1970s properties is the primary emerging call — tiles loosening rather than displacing at the Hardenhuish rate. 1980s flat roof failures are the secondary category, with fascia and gutter deterioration across both eras.
Cocklebury is at the optimal intervention point for nail sickness — early enough to phase the work, late enough that the problem is confirmed rather than suspected. We advise on the most cost-effective intervention for each slope's condition.
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 UsCocklebury is a Chippenham district of 1960s–70s concrete-interlocking-tile housing close to the town centre and the railway. On this kind of stock, the problems we see most in Cocklebury are nail sickness across the concrete-tile roofs, dropped ridge and verge mortar, and end-of-life felt underlay. Cocklebury sits low near the Avon and the railway on the north-east of the town.
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.
Cocklebury's post-war housing generally has driveway and side access, though the streets nearest the centre and station are tighter. Scaffold and skip permits go through Wiltshire Council, and on the residential roads off Cocklebury 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.
