Veteran owned pressure washing

Roof Soft Washing

Those black streaks are a living organism. Low pressure removes it without touching the shingles.

The dark streaks running down a Florida roof are not dirt and will not wash off in rain. They are gloeocapsa magma, an algae that feeds on the limestone filler in asphalt shingles and spreads a little further every season.

Roofs are never pressure washed. Pressure strips the granules that protect the shingle and shortens the life of the roof, which is the opposite of the point. Soft washing applies a solution that kills the organism and lets it rinse away, leaving the shingle intact.

Why it matters

Algae eats the shingle it grows on. Removing it protects a roof that costs many times what cleaning it does — and some insurers take an interest in roof condition.
