Roof Moss Removal & Treatment
Moss lifts shingles and refills your gutters. We remove it gently and treat the roof so it stays gone longer.
From $349 including gutter cleanupWhat to expect
Moss thrives on shaded, north-facing Portland roofs. It holds moisture against shingles, lifts their edges, and sheds into your gutters every time it rains, which is why moss-covered roofs clog gutters twice as fast.
We remove moss by hand and with soft brushes, never with a pressure washer that strips granules and voids roofing warranties. Then we apply a moss treatment and finish by cleaning out the gutters so the debris does not sit there all winter.

Roof Moss Removal FAQ
Do you pressure wash roofs?
No. Pressure washing strips the protective granules from asphalt shingles and can void the manufacturer warranty. We use hand tools, soft brushes and treatment.
When is the best time for moss removal?
Late summer through fall, before the heavy rains, or any dry window in winter and spring. Treatment works best when it has a dry day to set.
How long does a moss treatment last?
Typically one to two years on shaded roofs. Zinc strips at the ridge extend that.
Is the treatment safe for plants and pets?
We use products labeled for roof use, apply them per the label and protect beds below. Tell us about ponds, edible gardens or pets and we adjust.
