When moss, algae and lichen are left untreated, they can look unsightly, can damage some types of roof tiles, and can contribute to blocking roof gutters creating further maintenance problems. Roof and canopy cleaning is particularly important when the weather turns colder because if moss becomes frozen during the winter months, it can cause a problem called “frost heave” and “ice dams”. These can cause considerable damage to tiles as well as causing problems due to the extra weight. Algae, mould and moss are all living organisms that are physically eating away at your roof as well as attracting a host of bugs that thrive in those conditions. Our commercial roof cleaning service will professionally and safely remove build-up of moss, dirt, algae and other organic matter from roofs and gutters. Our process only causes minimal disruption, but we are prepared to work outside of normal working hours.
