Moss, algae, lichens & mildew break down the bond between the granules and the asphalt shingle. The granules protect the asphalt from ultra violet light, which breaks down the asphalt. Tree debris on the roof is cleaned away gently with compressed air or by gently washing the shingle in order to avoid shingle damage! After cleaning, an application of Moss Out can be applied to assist in preventing the moss from coming back!
