Soft wash roof cleaning that ends the black streaks

Superior Window Cleaning removes the black streaks from Sarasota area roofs with soft washing: a low-pressure detergent treatment that kills the algae causing the stains without damaging shingles or tile. No pressure washer ever touches your roof.

Those black streaks are alive

The dark stains on Gulf Coast roofs are Gloeocapsa magma, an airborne algae that feeds on the limestone filler in shingles and spreads in our humidity. It shortens shingle life, holds heat, and makes a sound roof look worn out. Pressure washing a roof strips granules and voids most shingle warranties, which is why reputable roofers tell you not to allow it.

Soft wash roof cleaning, the manufacturer-approved method

We apply a roof-cleaning solution at garden-hose pressure, let it kill the algae, and rinse gently. Shingle, tile, and metal roofs all get the same low-pressure treatment. The streaks disappear, and because the organism is dead rather than shaved off, the roof stays clean far longer.

Gutters and downspouts are flushed of runoff, and landscaping below the roofline is protected and rinsed throughout the job.

How it works

1. Roof assessment

   We look at the material, pitch, and growth from the ground and quote the cleaning without walking your shingles unnecessarily.

2. Soft wash treatment

   The solution goes on at low pressure, dwells, and does the killing. No blasting, no granule loss.

3. Rinse and protect

   We rinse the roofline and your plants, then walk the property with you to confirm the result.
