Moss removal, soft washing and biocide treatment across Dún Laoghaire. Extends roof life and restores appearance.
Dún Laoghaire homeowners trust Peak Roofing for roof cleaning. Moss, lichen and algae growth on tiles and slates traps moisture against the roof surface, accelerating mortar erosion and eventually the tiles themselves. Our roof cleaning specialists use low-pressure soft washing combined with a professional biocide treatment throughout Dún Laoghaire — far safer and more effective than high-pressure jet washing, which cracks tiles, displaces ridge mortar and forces water under the overlap. A professionally cleaned and biocide-treated roof in Dún Laoghaire stays clear for significantly longer and reduces the frost damage risk that comes with moisture trapped in moss growth.
