Roof Soft Wash

Remove black streaks (algae) without damaging shingles.

Those black streaks on asphalt shingles are gloeocapsa magma — a hardy algae that eats shingle granules. Pressure washing a roof voids most warranties. We use a low-pressure soft wash with manufacturer-approved cleaners that kill the algae and restore the roof's appearance, quoted to your roof's size and pitch.

FAQ

Roof Soft Wash — common questions

Is roof cleaning safe for asphalt shingles?

Yes, when it's done by soft washing. We use low pressure and manufacturer-approved cleaners that kill the algae without stripping the protective granules. Pressure washing a roof, on the other hand, damages shingles and voids most warranties.

What are the black streaks on my roof?

A blue-green algae called Gloeocapsa magma. It feeds on the limestone in asphalt shingles and thrives on shaded, north-facing slopes. Left alone it eats away the granules that protect your roof.

Why is roof cleaning quoted instead of a flat price?

Roofs vary too much by size, pitch, and access for a menu price. We look at yours, scope it properly, and send a written quote — free and with no obligation.
