Roof cleaning starts from £600 for a terraced property, £650 for a semi-detached, and £800 for a detached home. Every job includes Clean + Biocide treatment as standard, the post-clean biocide treatment inhibits lichen and algae regrowth at the root level and provides 3–5 years of protection. We provide free, no-obligation quotes for every job.

Our post-clean biocide treatment inhibits algae, lichen and organic regrowth at the root level. Moss is physically removed during the clean, and the biocide treatment prevents it returning. Results typically last 3-5 years depending on your local environment and tree coverage. We recommend a maintenance treatment every 2-3 years to keep your roof looking its best.

Yes, when done correctly. We use the appropriate pressure for each surface type. Block paving, tarmac, concrete and resin driveways all require different techniques. We never use high pressure on surfaces that could be damaged, and we use a surface cleaner for an even, streak-free finish.

We work in most weather conditions but will reschedule if conditions are unsafe or would affect the quality of the work. Soft washing and biocide treatments should not be applied in heavy rain. We'll always communicate clearly if we need to reschedule.
