Frequently Asked Questions
What's the best way to clean black algae stains from my roof in Fairfax?
The most effective method for Fairfax homes is a professional soft wash treatment. We use eco-friendly, algae-specific solutions that kill the growth at the root without damaging your shingles. Pressure washing can often strip away the protective granules, so our gentle approach safely removes the stains and helps prevent them from quickly returning, restoring your roof's clean look.
How can I tell if my aging shingles need repair or a full replacement?
Look for key signs like curled or cracked shingles, bald spots where granules are missing, or shingles that are buckling. In Fairfax, frequent temperature changes can accelerate this aging. We offer free, thorough inspections to assess the damage. Often, localized repair is sufficient, but if wear is widespread or you have leaks, a full replacement with modern, durable materials is the most cost-effective long-term solution.
Why do roofs in our area seem to get algae stains so often?
Fairfax's humid climate, combined with plenty of tree cover, creates the perfect environment for Gloeocapsa magma algae to thrive. This organism feeds on moisture and limestone filler in asphalt shingles, leaving those characteristic dark streaks. While mostly cosmetic, it can shorten shingle lifespan. Our preventative cleaning services and recommendations for algae-resistant shingles during replacements are tailored to combat this very common local issue.
