Glasgow's wet climate keeps roofs damp for long stretches, and that is exactly what moss, lichen and algae thrive on. Beyond looking tired, heavy growth traps water against tiles and slates and can work into the joints. A local roof cleaner can clear it away and treat the surface to slow regrowth.
Given the amount of traditional slate across the city, a gentle roof softwash is often the sensible approach.
Comparing two or three professionals helps you gauge fair roof cleaning prices and find someone whose method suits your property. Ask about access, the treatment used and whether tile cleaning is part of the quote.

Bark's data suggests £400 to £1,000 per job, roughly £8.50 to £14 per square metre. The total depends on roof size, access, and whether it is a manual scrape and biocide treatment or a full steam clean, so comparing quotes is worthwhile.
