Professional moss removal and roof cleaning across Chippenham and Wiltshire. Safe soft-wash methods — no pressure washing on tiles. Biocide treatment and long-term maintenance plans. Free no-obligation quotes.
Chippenham's Avon Valley location creates faster moss growth than most Wiltshire towns. We remove it safely and treat to prevent rapid regrowth.
Manual moss removal from tile surfaces, ridges, hips and valleys. We clear all debris from gutters and valleys after removal — blocked valleys from cleared moss are the most common post-cleaning problem when contractors don't follow through.
Get a quote →Post-removal biocide application to inhibit moss, lichen and algae regrowth. We use biodegradable, tile-manufacturer-approved solutions — not bleach-based products that damage tile coatings and run off into Avon Valley gardens.
Get a quote →Always included as part of our roof clean. Cleared moss falls into valleys and gutters — we remove it all before leaving site. Gutters are flushed and flow-tested before we finish.
Get a quote →Annual or biennial roof and gutter maintenance visits. We clean, inspect, and report — noting any tiles or flashings that need attention before they become emergency calls. Available for Chippenham residential and commercial properties.
Get a quote →Sealant coating applied after cleaning on concrete tile roofs to restore protective surface and significantly extend tile life. We use breathable, tile-compatible coatings — not film-forming sealants that trap moisture.
Get a quote →Full roof inspection during cleaning visit — tiles, flashings, ridge, hips, valleys and gutters checked and reported on. Written report provided, with prioritised repair recommendations. Included in cleaning quote at no extra charge.
Get a quote →Safe removal, no pressure washing. Covers Chippenham and all of Wiltshire.
Chippenham's position in the Avon Valley creates consistently higher ambient moisture than surrounding higher-ground towns like Calne or Malmesbury. The river corridor generates morning mist that settles on north and east-facing roof surfaces, and the heavy tree canopy over much of the residential town — particularly around Bath Road, the riverside walks and older residential streets — keeps roofs shaded and damp for longer into the morning than in open countryside.
The combination of shade, moisture and the slightly alkaline dust that settles on concrete tile surfaces makes Chippenham's roofs among the fastest-growing for moss in north Wiltshire. Hardenhuish's 1960s–70s concrete tile stock is particularly susceptible — the rough original surface texture of these tiles provides excellent moss anchorage and they have been retaining moisture for half a century. We recommend annual cleaning on the most affected Hardenhuish properties and biennial cleaning on most other Chippenham addresses.
Three-bed semi moss removal and biocide treatment: £250–£450. Detached four-bed: £400–£650. Includes gutter clearing and written inspection report. Annual maintenance plan (includes gutter clean, inspection, minor repairs): from £150/year. Free written quote before any work starts.
"On the annual plan for three years now — roof clean, gutter clear and inspection each autumn. They spotted a loose ridge tile on the second visit before it became a problem. Worth it entirely for the peace of mind, let alone the work."
"North-facing semi with heavy moss that had been lifting the edges of tiles on the back slope. Carefully removed by hand, biocide applied, gutters flushed. Written report confirmed tiles were in good condition underneath. Relieved."
"Clay plain tile cottage — needed careful handling. No pressure washing, soft biocide treatment. Roof looks ten years younger and they confirmed the tiles themselves are in excellent condition. Exactly the approach a historic building needs."
Most Chippenham properties benefit from cleaning every 3–5 years. Properties in the Avon Valley — particularly those backing onto the river or with heavy tree canopy overhead — need attention every 2–3 years. Moss holds moisture against tiles and accelerates surface degradation; left too long it can lift tiles at their edges.
No. Pressure washing removes the protective surface coating from concrete tiles and can fracture soft or aged clay tiles. We use low-pressure soft washing combined with manual biocide application. This is the approach recommended by tile manufacturers and the NFRC.
Biocide treatment significantly slows regrowth — typically giving 2–4 years before moss re-establishes. The rate depends on tree canopy, roof orientation and local moisture levels. North-facing roofs in the Avon Valley will regrow faster than south-facing roofs on higher, drier ground.
Not if you're replacing tiles within 12 months — cleaning a roof you're about to replace is wasted money. If the tiles are in good condition and the moss is the issue, cleaning is far more cost-effective than re-roofing. We assess tile condition during the free survey and advise honestly.
Soft-wash methods are safe on clay plain tiles and stone slates when correctly applied. We avoid high-pressure methods on all historic and conservation area stock. For listed buildings, we'll discuss the proposed treatment method with the relevant conservation officer if requested.
Not if done correctly. We use manual removal and soft-wash biocide methods — no pressure washing, which removes protective coatings from concrete tiles and can fracture aged clay tiles. Our methods are consistent with NFRC guidance and tile manufacturer recommendations.
Yes — a visibly clean, well-maintained roof significantly improves kerb appeal and is a positive indicator in any property survey. Heavy moss is often flagged in pre-purchase surveys as a maintenance concern. A professional clean and biocide treatment before sale is a worthwhile investment.
Safe soft-wash methods. Annual maintenance plans available. Chippenham and all of Wiltshire.
