Professional Roof Washing in Austin TX
Those dark black streaks running down Austin roofs are not just unsightly - they are actively damaging your shingles. The culprit is Gloeocapsa magma, a type of cyanobacteria (commonly called algae) that feeds on the limestone filler used in asphalt shingles. Austin's warm, humid climate is ideal for this organism, which is why it spreads so rapidly from roof to roof across neighborhoods in South Austin, Barton Hills, Hyde Park, and throughout the metro.
Left untreated, this algae shortens shingle life by breaking down the protective granules, increases your home's cooling costs by darkening the roof and absorbing more heat, and can spread to neighboring roofs. Regular roof cleaning every 2-3 years prevents these problems and can add years to your roof's service life.
We use the soft wash method exclusively for roof cleaning. This means applying specialized cleaning solutions at very low pressure - less than a garden hose - that penetrate the algae and kill it at the cellular level. Unlike pressure washing, soft wash results last 2-4 years and will not void your roof warranty. The ARMA (Asphalt Roofing Manufacturers Association) specifically recommends this approach.

Roof Washing Questions
What causes black streaks on my Austin roof?
Black streaks are caused by Gloeocapsa magma, a cyanobacteria that feeds on the limestone filler in asphalt shingles. Austin's warm, humid climate is ideal for this organism. The dark coloration comes from a protective pigment the bacteria produce to shield themselves from UV light. Soft washing eliminates this growth completely.
Is soft washing safe for my shingle warranty?
Yes. Soft washing is the ARMA-recommended cleaning method and does not void shingle warranties. High-pressure washing would void warranties because it removes the protective granule coating from shingles. Our soft wash technique never uses pressure that could cause granule loss.
How long does roof washing take in Austin?
Most Austin residential roofs take 2-4 hours to complete. Larger homes or roofs with significant organic growth may take longer. You will see immediate visual improvement after cleaning, with full results visible as the roof dries over 24-48 hours.
How often should I have my Austin roof washed?
In Austin's climate, we recommend roof washing every 2-3 years for most homes. Properties with more shade, near water features, or in areas with heavier tree coverage may benefit from more frequent cleaning. Once you see black streaks appearing, it is time to schedule service.
