Roof cleaning · Marin County

Roof moss gone, shingles safe.

Marin fog grows moss and lichen fast. We remove it with a low-pressure soft wash, never a pressure washer, so your shingles keep their granules and your roof lasts longer.

How we do it

Done the safe way

  1. Look first

    We check your roof type and condition and give you a price on the spot.

  2. Protect your yard

    Plants below are soaked and covered so nothing gets hurt.

  3. Treat and rinse

    Moss and lichen are treated at low pressure. Remaining moss dies off and washes away with the rain.

Questions

Roof Cleaning FAQ

Will pressure washing damage my roof?

It can. High pressure strips the protective granules off asphalt shingles and can void the warranty. We use a low-pressure soft wash instead.

How much does roof moss removal cost?

It depends on the roof size, pitch and how heavy the moss is, so we quote on site for free. Most homes are priced as one flat number.

Is the treatment safe for my plants?

We pre-wet and physically cover your plants and landscaping before we start, and we never spray in the wind.

How long until the moss is gone?

Loose moss is removed the same day. Anything left is killed by the treatment and washes off over the next few rains.

What roof types do you clean?

Composition and asphalt shingle roofs are most common. We look at tile and wood shake roofs in person before quoting.
