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.
Single installation: £400–£700. Replacement: £200–£450. Flat roof light: £500–£900. Flashing repair: £150–£350. Free quote — call 01249 247 076.

01249 247 076Stanley 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.
For a new window we check rafter spacing, the room below and planning status; for a leak we diagnose the flashing.
Rear-slope installations are usually permitted development; front-slope, listed and conservation-area need checking first.
A fixed price for install or flashing repair, agreed before work.
The window is fitted and sealed with the correct flashing kit for your specific tile or slate profile.
We test for watertightness, make good internally where agreed, and guarantee the work.
| Job | Typical duration |
|---|---|
| Flashing kit repair | 2–4 hours |
| Replacement in existing opening | half to full day |
| New roof window (rear slope) | 1 day |
| Multiple windows | 1–2 days |
| Dormer roofing / repair | per scope |
Cutting a new opening needs dry conditions so the roof is never left open to rain; we weather-schedule new installations.
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.
Workmanship carries our 10-year guarantee; the window and flashing kit carry manufacturer warranties (Velux units typically 10 years) on top.
