Those black streaks on your roof are living algae — and they're eating your shingles. Our gentle soft-wash roof cleaning kills the growth at the source and restores your roof's look without the high pressure that voids warranties.
The dark streaks running down Houston roofs are Gloeocapsa magma, a blue-green algae that feeds on the limestone filler in asphalt shingles. Left unchecked it spreads, lifts granules, traps heat, and shortens the life of your roof. High-pressure washing would strip those granules and void your manufacturer warranty — so we never use it. Instead we apply the soft-wash method recommended by shingle manufacturers and the ARMA: low pressure plus professional treatments that kill algae, moss, and lichen at the root.
Our heat, humidity, and frequent rain make the Gulf Coast one of the worst regions in the country for roof algae. North-facing slopes that stay shaded stay damp, and that's where growth takes hold first. Cleaning every two to three years keeps your roof looking new, helps it reflect heat instead of absorbing it, and protects one of the most expensive components of your home.
A new roof is a major expense. Soft washing is a fraction of the cost of premature replacement and is the only method that cleans without damaging the shingle surface. We work safely from ladders and the ground, protect your landscaping from runoff, and leave your roof looking years younger.
