Roof Cleaning in Anchorage — What to Expect
A cleaner roof, more curb appeal
Those dark streaks running down a roof are usually a hardy blue-green algae (Gloeocapsa magma), not permanent stains. A proper soft wash clears the algae, moss, and lichen and brings back the original color of the roof on a Anchorage home.
Soft wash, not high pressure
Blasting a roof with a pressure washer can strip the protective granules off asphalt shingles and void some warranties. Roof cleaning is done with low-pressure soft washing and cleaning solutions that do the work — ask any contractor how they clean before you hire.
Protect the roof you already paid for
Moss holds moisture against shingles and lifts their edges; algae feeds on the limestone filler in them. Clearing both helps a Anchorage roof shed water and reach the lifespan it was built for — far cheaper than an early replacement.
