Moss and algae build up gradually on roofs, often starting on shaded slopes or under overhanging trees before spreading further. Once established, the growth holds moisture against the tiles, which isn't good for the roof covering over time. A roof cleaner will typically remove it and can apply a preventive treatment afterwards.
Working at height on a pitched roof carries real risk, and an incorrectly used pressure washer can crack tiles or force water under slates. Most homeowners find it worthwhile to bring in a roof cleaner with the right harnesses and softwashing equipment instead.
Spores travel on the wind and settle readily on any damp, shaded roof surface, which is why a preventive treatment after the clean matters. Roof cleaners covering Cirencester also tend to work in Cheltenham, Gloucester, Stoke Gifford and Tetbury, so compare a few quotes on Bark before booking.
Bark's data suggests roof cleaning in Cirencester typically costs £400 to £1,000 per job, roughly £8.50 to £14 per square metre. The final price depends on your roof's size and access, and whether it's a manual scrape and biocide treatment or a full steam clean.
