Hardenhuish is Chippenham's largest post-war estate, positioned 1 mile north of the town centre. Exposure is typical for north Chippenham. The defining factor is age: built almost entirely 1958–1978, the entire estate is at the nail sickness threshold simultaneously.
Near-uniform 1958–78 concrete interlocking tile throughout. The most concentrated nail sickness zone in north Wiltshire. Original fixing nails are 55–65 years old and corroded through on the majority of properties.
Nail sickness is the single dominant call from Hardenhuish — more re-roof enquiries originate here than from any other Chippenham area. Properties that have had tiles re-fixed repeatedly by different contractors are on a maintenance treadmill that only re-roofing resolves.
We are 1 mile from Hardenhuish — 3 minutes. We carry out more nail sickness surveys here than anywhere else. The recommendation is almost always a full or phased re-roof, quoted slope-by-slope with both options presented side by side.
Moss growth rates vary across Chippenham's neighbourhoods depending on moisture exposure and tree cover. River-adjacent areas (Hartham, Monkton Park) see the fastest growth — 2-year cleaning cycles recommended. Central and elevated streets have moderate growth — 3–5 years. We use manual removal and soft-wash biocide on all Chippenham properties — no pressure washing, which damages protective coatings on concrete tile and can fracture aged clay tile.
A written inspection report is included with every cleaning visit — identifying any tiles, mortar or lead issues noted during the close-access cleaning work. Many repair recommendations originate from cleaning visits rather than specific surveys. Where the roof is approaching an age threshold, we note this clearly in the report.
Every 3–5 years on most Hardenhuish properties. North-facing slopes under tree cover may need more frequent attention.

01249 247 076Hardenhuish is an established Chippenham district dominated by 1960s–70s concrete-interlocking-tile semis and detached houses on the western edge of town. On this kind of stock, the problems we see most in Hardenhuish are nail sickness across the 1960s–70s concrete-tile roofs, dropped ridge and verge mortar, and end-of-life felt underlay. Hardenhuish sits on the exposed western edge of Chippenham, catching the prevailing south-westerly weather first.
We assess the moss coverage, tile type and condition, and set up safe access.
Moss is scraped and brushed off by hand — never pressure washed, which damages tiles.
A biocide is applied to kill remaining spores and slow regrowth over the following seasons.
We clear the moss debris from the gutters so it doesn't wash back down.
A written note of anything we spot up there, with no obligation to book it.
| Job | Typical duration |
|---|---|
| Moss removal + biocide (semi) | half to full day |
| Full clean + biocide (detached) | 1–2 days |
| Biocide-only treatment | 2–4 hours |
| Bungalow / single storey | 2–4 hours |
| Gutter clear add-on | 1–2 hours |
Biocide works best applied in dry conditions; we time treatment for a dry spell so it isn't washed off before it acts.
Hardenhuish is post-war estate housing with generous side access, driveways and space for scaffold and skips. Scaffold and skip permits go through Wiltshire Council, and on the estate roads off Bristol Road we allow extra time for setup. Access is always itemised in your written quote, never a hidden extra.
The clean and biocide are guaranteed for workmanship; regrowth timescales depend on aspect and canopy, and we're honest that no single treatment is permanent.
