Roof Washing in Sarasota, FL
Those black streaks on your roof aren't dirt — they're Gloeocapsa magma, an algae that literally feeds on your shingles. SoFlo's roof washing uses a dedicated low-pressure soft-wash treatment that kills the growth at the root without the granule-stripping damage of high pressure.
What professional roof washing gets you.
- Removes black algae streaks, mold, and lichen safely
- Extends roof life — algae eats the limestone in shingles
- Protects your roof warranty (high pressure can void it)
- A fraction of the cost of a premature roof replacement
How SoFlo does it right.
We walk the roofline, check shingle or tile condition, and flag any pre-existing damage before we start.
Landscaping, gutters, and downspout runoff areas are saturated and shielded before any solution touches the roof.
A calibrated soft-wash blend is applied at garden-hose pressure — the ARMA-recommended method for asphalt shingles.
Stains lift during the wash; the heaviest algae continues to fade over the following weeks as rain rinses it away.
Roof Washing questions we hear a lot.
Is roof washing safe for my shingles?
Yes — when it's done with soft washing, which is the method ARMA (the shingle industry's own association) recommends. High pressure is what strips granules and shortens roof life; we never use it on roofs.
How long do results last?
Because the treatment kills the algae at the root instead of just rinsing the surface, most Sarasota roofs stay clean for 3–5 years depending on shade and tree cover.
Will the treatment harm my plants or pets?
No. We pre-soak all landscaping, manage runoff, and rinse everything down afterward. Once surfaces are dry, the area is safe for pets.
