London Road runs from Chippenham town centre east toward Pewsham, with moderate exposure and consistent urban tree cover that creates above-average autumn debris loading in gutters.
Dense Victorian and Edwardian terracing on the town-centre end transitions to 1930s semis at the Pewsham fringe. Clay plain tile and slate on the oldest stock; early concrete tile on the 1930s properties now entering the nail sickness window.
Lead valley failures on Victorian terraces are the primary call. The high density of similar-age properties means issues cluster by street — when lead fails on one London Road terrace, adjacent properties from the same building phase are typically in the same condition.
We carry out more pre-sale roof surveys on London Road than any other Chippenham street — buyers recognise the age profile and request specialist inspections routinely. We provide written reports with photographs suitable for solicitors.

01249 247 076The London Road area is one of Chippenham's Victorian and Edwardian districts — brick terraces and villas with clay-tile and slate roofs, close to the town centre. On this kind of stock, the problems we see most in the London Road area are failing Victorian leadwork in valleys and around chimneys, slipped slates, and eroded lime pointing on brick stacks. The London Road area sits on the eastern approach to the town centre, its older roofs weathered by decades of exposure.
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.
The London Road Victorian terraces have no rear access, so materials and waste pass over the front, and slate or clay matching is often needed. Scaffold and skip permits go through Wiltshire Council, and on London Road itself, the Victorian side streets off it 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.
