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.
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 Sheldon properties. North-facing slopes under tree cover may need more frequent attention.

01249 247 076Sheldon 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 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.
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.
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.
