Roof coating in the UK
Applied coatings over existing roofs — cosmetic rejuvenation for concrete tile, not a substitute for replacement.
Typical UK cost range
£15–£45/m²
National baseline. City-specific ranges are adjusted for local labour and access costs on the city pages below. See the full UK cost guide for the methodology and the factors that move a quote.
What the job involves
Roof coatings are sprayed or painted coatings applied over existing tile (usually concrete) to seal surface crazing and restore colour. Done well, on a sound roof, they can add 8–15 years of cosmetic and weather-protective life. Done badly, or sold as a substitute for replacing a failing roof, they are one of the more common UK domestic roof scams.
A legitimate coating job starts with a thorough clean, moss removal, any necessary repairs, a primer, and then two coats of the coating product. Cheap quotes often skip the clean and the primer, and the coating peels within a few years.
What changes the price
- Roof area in m².
- Condition of the existing tile — heavy moss or damaged tiles push the price up because of the prep stage.
- Coating product choice (acrylic, silicone, polyurethane).
- Whether scaffolding is needed.
Timeline: Usually 2–4 days on site including prep.

Is a roof coating a substitute for a re-roof?
No. Coatings are cosmetic and weather-protective — they don’t fix failed underlayment, perished battens, or structural issues. If a quote is presenting coating as an alternative to a re-roof on a roof that genuinely needs replacing, that is the sales pitch to walk away from.
How long does a roof coating last?
On a sound roof with proper prep and a good product, 8–15 years. On a failing roof with bad prep, 1–3 years. The difference is almost entirely down to how thoroughly the prep was done.
