Those dark streaks running down your roof aren't just dirt — they're Gloeocapsa magma, a type of algae that feeds on the limestone in your shingles. Left untreated, it shortens your roof's lifespan and drives up cooling costs by reducing reflectivity.
We use a soft wash system — low pressure combined with professional-grade biodegradable cleaning solutions — that kills algae, mold, mildew, and lichen at the root without damaging your roofing material. This method is safe for asphalt shingles, concrete and clay tile, and metal roofing.
Results last 2–3 years on average. We also clean gutters, soffits, and fascia during the process to give your roofline a complete refresh.
