A roof covered in moss and algae does more than look untidy, it can trap moisture against tiles and slates over time. A roof cleaner in Westhill can strip this back safely, usually with a softwash or manual scrape followed by a biocide treatment. Catching the buildup early tends to make the job quicker and more affordable overall.
