Roof soft wash

Those black streaks are gloeocapsa magma, a living algae eating your shingle granules. Low-pressure chemistry kills it. High pressure would take your roof's life with it — we never use it up there.

Price this $0.35 per sq ft · $449 minimum · typical job $449–$1450

Questions

What people ask about roof soft wash.

From customers

What they said afterwards.

Showed up in the window, did the whole house of windows including tracks, and left the sills cleaner than they found them. No upsell pressure at all.

Second time using them for the panels. They send the inverter reading before and after, which nobody else does. Output was up 14% the next day.

Roof had black streaking down the whole north face. They tarped the beds first, which the last outfit didn't, and my hedges survived this time.
