Most roofs pick up moss and algae gradually, usually starting on shaded slopes or spots close to trees. Once established, the growth holds water against the tiles, which over time isn't good for the roof covering. A roof cleaner will typically remove it with a manual scrape and biocide treatment or a full steam clean.
Most homes only need attention every three to five years, though a heavily shaded roof or one near overhanging branches may build up moss faster and need cleaning sooner.
A straight pressure wash can crack fragile tiles or push water under slates, which is why many roof cleaners prefer softwashing, using lower pressure combined with a biocide solution instead.
Roof cleaners covering Tetbury also tend to work in Cheltenham, Gloucester, Cirencester and Stoke Gifford, so it's worth comparing a few quotes on Bark.
Bark's data suggests roof cleaning in Tetbury typically costs £400 to £1,000 per job, roughly £8.50 to £14 per square metre. Price depends on your roof's size and access, and whether it's a manual scrape and biocide treatment or a full steam clean.
