Slate and clay tiles across Thornbury pick up moss, lichen and green algae quickly, especially on shaded, north facing slopes. A roof cleaner can strip that growth back with a softwash or a full steam clean, depending on how established the moss is and how the roof was built.
Most jobs start with a walk round assessment, then either a gentle biocide softwash or a more thorough manual scrape for heavier moss. Fascias and soffits are often done at the same time, since grime tends to run down from the roofline.
Roof cleaners who quote in Thornbury also tend to cover Cheltenham, Gloucester, Cirencester and Stoke Gifford, so you're not limited to a small pool of tradespeople.
Bark makes it straightforward to compare a few local roof cleaners before deciding, so you can weigh up price, availability and the method they recommend for your roof.
Bark's data suggests roof cleaning in Thornbury costs £400 to £1,000 per job, working out at roughly £8.50 to £14 per square metre. The final figure depends on roof size, access, and whether the work is a manual scrape and biocide treatment or a full steam clean.
