Roof cleaning prices

Roof size

Larger roofs naturally take longer to clean and treat. Most contractors price by the square metre or overall roof area.

Roof type & condition

Heavy moss or lichen build-up, delicate tiles (like natural slate), or steeply pitched roofs may cost more due to additional time and care required.

Access requirements

If scaffolding or a cherry picker is needed rather than just a ladder, this will add to the total cost.

Treatment included

Some quotes include a biocide treatment or sealer to prevent regrowth — this is worth paying for as it extends the time before your next clean.

Your location

Labour rates vary across the UK. London and the South East typically sit at the higher end, while the North and Midlands tend to be lower.
