A roof left untreated for a few years can gather moss, algae and dark staining, which can leave the whole property looking a good deal more tired than it really is. A roof cleaner in Holywood can bring tiles and slates back to a much cleaner finish using a softwash or manual scrape. Most jobs also include a preventive treatment so the results last longer.
Costs are generally quoted per square metre, with the total depending on roof size, access, and whether the job is a manual scrape and biocide treatment or a full steam clean. Comparing a few quotes through Bark makes it easy to see what's reasonable for your property.
Roof cleaners working in Holywood also frequently cover Bangor, Newtownards and Comber, so they know the roof types common across this part of Ards and North Down well.
Bark's data suggests roof cleaning typically costs £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. Larger roofs or those needing careful access tend to sit towards the top of that range.
