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!

Removing moss from your roof can be a dirty job. That’s why we do a thorough cleanup afterwards, clearing our your gutters and surrounding area cleaner than they were when we came.

Alpine Roof Care also offers general pressure washing services for your driveway, patio’s and decks, sport courts and siding.
