Roof cleaning prices, by the property.
Roof cleaning priced the way the trade prices it: a job price by property type and method, with the access surcharge itemised honestly rather than hidden in a bargain headline.
How it prices: A job price by property type, moved within the band by roof size, pitch and access in that order. A manual moss strip plus softwash is the common combination; the access surcharge is itemised. A softwash re-treatment plan (£250) is the recurring protective upsell, and roof coatings (£1,500–£4,000+) are a survey job. Manual bands: terraced £150–£350, semi £250–£500, detached £400–£900+, softwash-only £200–£600. Treat the output as a starting band, not gospel — gather 15–30 local price points before you commit to a number.
What roof cleaning costs in the UK in 2026
Roof cleaning is priced per job by property type: a terraced house is typically £150–£350, a semi-detached £250–£500 and a detached house £400–£900+. A softwash-only treatment (biocide, no manual strip) is £200–£600. Steep pitch and awkward access add a surcharge; a full manual moss strip plus softwash is the common combination.
Be wary of a headline price that ignores safe access — a roof that needs careful tower or roof-ladder work can't be done properly on a bargain quote.
If you're the one working at height
The price moves on band, size, pitch and access in that order, and the honest operator itemises the access surcharge rather than hiding it. Add-ons stack while the kit is up — a gutter clear, a conservatory roof — and a softwash re-treatment plan (£250) turns a one-off into a recurring visit. Roof coatings (£1,500–£4,000+) exist but the manual sells them rarely.
The full method — banded pricing, access surcharges, softwash vs strip, the add-on stack — is in The Roof Cleaning Works, £47.
Pricing questions, answered plainly
How much does roof cleaning cost in the UK?
By property type: a terraced house is £150–£350, a semi £250–£500 and a detached house £400–£900+. A softwash-only treatment is £200–£600, with a surcharge for steep pitch or difficult access.
What's the difference between softwash and moss removal?
Softwash applies a biocide that kills moss and algae over the following weeks with no scraping; manual moss removal scrapes it off for an immediate result. The common job is a manual strip followed by a softwash.
Do I need a roof coating?
Rarely. A coating is a £1,500–£4,000+ job, and reputable operators treat it as an honest, occasional option rather than a default upsell after a clean.
Why does access change the roof cleaning price?
Because safe work at height drives the cost — a steep pitch needing a roof ladder, or a conservatory to protect, adds an access surcharge (often £30–£130) that a good quote itemises rather than hides.
