A well maintained roof says a lot about a property. Homes in Newcastle, in Newry, Mourne and Down, are exposed to plenty of rain over the year, which gives moss and algae the damp conditions they need to spread across roof tiles and slates. A roof cleaner can assess the extent of the build up and recommend the right approach.
Left in place, moss holds moisture against the roof surface, which can gradually loosen tiles and let damp work its way into the loft. A softwash treatment clears this growth gently, and a preventive treatment applied afterwards helps slow down how quickly it returns, so the roof stays presentable for longer.
Roof cleaners working in Newcastle also take on jobs in Ballynahinch, Newry, Downpatrick and Warrenpoint, so there's a good chance of finding someone who knows the local area well and can offer a fair quote quickly.
Bark's data suggests roof cleaning in Newcastle typically costs £400 to £1,000 per job, roughly £8.50 to £14 per square metre. The final price depends on roof size, access, and whether it's a manual scrape and biocide treatment or a full steam clean.
