Sheldon sits on Chippenham's eastern fringe toward the M4 corridor, with housing built in phases from the 1950s to the early 1990s. Early post-war properties have concrete tile at the nail sickness threshold. 1980s extensions have felt flat roofs now 35–45 years old and approaching end of life. Original timber fascia boards on the 1960s stock are 55–60 years old and frequently rotten behind paint.

Sheldon occupies Chippenham's eastern fringe with mild exposure. The M4 proximity brought development in multiple phases, creating a mixed age profile where maintenance needs vary significantly property by property.
Post-war and 1960s properties have concrete tile at the nail sickness threshold. 1980s properties have flat roof extensions now 35–45 years old. 1990s stock is entering the first maintenance cycle.
Three parallel maintenance categories: nail sickness on the oldest stock, felt flat roof failures on 1980s extensions, and fascia deterioration on 1960s timber boards. Often multiple categories present on the same property.
Sheldon's mixed build phases mean we arrive at every survey with a broader range of materials than single-era areas — clay tile, concrete profiles, GRP materials and UPVC fascia stock. Pre-sale surveys are particularly popular here.
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 UsSheldon is a Chippenham district of largely post-war and later 20th-century concrete-tile housing on the north-western side of town. On this kind of stock, the problems we see most in Sheldon are nail sickness across the concrete-tile estate roofs, dropped verge mortar, and end-of-life underlay. Sheldon sits on the north-western side of Chippenham, exposed to the prevailing south-westerly weather.
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.
Sheldon is estate housing with generally good driveway and side access for scaffold and skips. Scaffold and skip permits go through Wiltshire Council, and on the estate roads around Sheldon 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.
