Across West London, roofs facing shaded gardens or overhung by trees are the ones most likely to develop moss, algae and lichen. Left unchecked, this growth can trap moisture and gradually work tiles and slates loose.
Prices vary with roof size, access, and whether the job is a manual scrape and biocide treatment or a full steam clean, so comparing quotes is worthwhile.
Roof cleaners listed on Bark for West London cover towns including Greenford, Isleworth, Harrow and Southall, making it easy to find someone local wherever you are in the area.
Bark's data suggests roof cleaning across West London typically costs £400 to £1,000 per job, roughly £8.50 to £14 per square metre, with the total depending on roof size, access, and whether it is a manual scrape and biocide treatment or a full steam clean.
