Roof Cleaning
Straffan

Peak Roofing and Building carries out professional roof cleaning and moss removal throughout Straffan. Over time, moss, lichen and algae growth on tiles and slates retains moisture against the roof surface, accelerating deterioration of the bedding mortar and eventually the tiles themselves. Our roof cleaning process uses low-pressure soft washing combined with a long-life biocide treatment — a far safer and more effective method than high-pressure jet washing, which can crack and dislodge tiles and wash away the mortar bedding protecting your ridge line. A properly cleaned and treated roof in Straffan stays clean for significantly longer and reduces the risk of tile damage caused by frost acting on moisture retained in moss growth.

Moss and algae growth is particularly prevalent on roofs in Straffan that have significant tree coverage or north-facing slopes that receive less direct sun. Properties in Straffan built in the 1970s and 1980s with concrete tile roofs are especially susceptible — the rough surface of concrete tiles provides an ideal base for moss spores to establish. We carry out free roof assessments across Straffan to determine the extent of growth, the condition of the tiles and ridge bedding, and the appropriate treatment approach. Where we identify underlying repair issues — cracked tiles, failed ridge bedding, blocked gutters — we will include these in the quote so the work is dealt with in a single visit.
