We have cleaning solutions that are specially formulated to kill living biomass, like moss or algae, on your roof. In addition, you can use a pressure sprayer with revolving brushes or other special attachments. However, the high pressure can cause damage to roofing materials so try soft washing. That is - use a pressure of 500 psi or less. A simpler method can be the zinc roof cleaning tape. Apply this strip to the top of your roof to prevent organic growth build-up.
A big part of keeping your roof in optimal condition involves a bit of repair. Prevent leaks, water pooling and more. A little time now, mean less costs in the future!
