Rowden stretches from Chippenham's southern edge into the rural fringe, encompassing 1960s–70s estate housing in the northern sections, 1990s–2000s development at Methuen Park, and occasional period farmhouse and cottage properties on the outer edge. Each era has its own maintenance profile — nail sickness on the 1960s–70s sections, flat roof extension failures on the 1990s–2000s properties, and lime mortar requirements on the rural fringe period stock.

Rowden stretches from Chippenham's southern edge into the rural fringe, creating the most varied exposure of any Chippenham neighbourhood. Rural fringe properties have more wind exposure and a higher debris load than central streets.
1960s–70s estate housing in the northern sections; 1990s–2000s development at Methuen Park; occasional period farmhouse and cottage properties on the outer edge. Three distinct maintenance profiles in one area.
Nail sickness on 1960s–70s sections; flat roof extension failures on 1990s–2000s sections; and lime mortar requirements on rural fringe period properties. Mixed property types require broader material preparation than single-era areas.
Rowden is the most materially diverse area in our Chippenham coverage — we carry clay tile, concrete tile profiles, GRP materials, lime mortar and period fascia profiles to Rowden visits given the range we encounter.
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 UsRowden is a Chippenham district on the southern edge of town mixing older Rowden Hill property with later 20th-century and modern housing. On this kind of stock, the problems we see most in Rowden are nail sickness on the mid-century stock, wind-lifted tiles on the exposed higher ground, and ageing felt on the older extensions. Rowden sits on rising ground on the south of Chippenham, its higher plots more exposed to wind.
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.
Rowden's mix ranges from tight older plots to open modern estates with driveway access for scaffold and skips. Scaffold and skip permits go through Wiltshire Council, and on the estate roads off Rowden Hill 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.
