What Affects the Price
Roof Size
Larger roofs take longer to treat and need more biocide product.
Tile Type
Concrete, clay and slate all need slightly different handling. See our roof cleaning service page for detail on each.
Pitch
Steeper roofs require more careful access and take longer to treat safely.
Access
Whether a roof ladder, cherry picker or full scaffolding is needed significantly affects cost.
Extent of Growth
Heavy, long-neglected moss buildup takes more time to manually remove before treatment.
Ridge & Repairs
Repointing loose ridge tiles, if needed, is quoted as an add-on.
What's Included in a Professional Quote

Is It Worth It?
Roof cleaning costs £500–£1,200. Roof replacement costs £5,000–£15,000+. Beyond the obvious saving, removing moss prevents frost damage to tiles, protects against gutter blockages, and extends the working life of the roof considerably.
Frequently Asked Questions
Typically £500–£700, depending on roof size, pitch and the extent of moss or algae growth.
Cost reflects safe access requirements (scaffolding or cherry picker), specialist biocide treatment, and the time needed for thorough manual moss removal — not a quick pressure wash.
Not always — many roofs can be cleaned safely with a cherry picker or roof ladder. Scaffolding is only used where access genuinely requires it, and is quoted separately.
