Protect Your Roof. Restore Its Beauty.

Moss may seem harmless, but it traps moisture, lifts shingles, and shortens your roof’s life. Our preventive treatment uses zinc sulfate or sodium bicarbonate—roof-safe compounds that kill existing moss and help prevent regrowth.

In the Pacific Northwest, experts recommend treating your roof every 6 to 12 months due to our damp, moss-prone climate. For heavy moss buildup, we also offer Moss Removal by Soft Wash & Brush to speed up cleanup and restore your roof’s appearance.

  • Targeted Treatment – We apply zinc sulfate or sodium bicarbonate (white powder) to the roof ridgelines and moss-prone areas.
  • Gutter-Friendly Setup – We use ladder stabilizers to protect your gutters and roofline while accessing your roof.
  • Gutter Condition Check – We inspect your gutters for blockages or poor drainage and notify you of any issues.
  • Removal Recommendation – For thick moss, we’ll recommend our Roof Moss Soft Wash & Brush service for best results.

What to Expect from Our Roof Moss Treatment

Ready for a clean, protected roof that stays moss-free longer—without harsh chemicals or pressure washing. We apply a white powder treatment (zinc sulfate or sodium bicarbonate) to the ridgelines and problem areas.

When it rains, the treatment activates, killing moss and preventing new growth for 6 to 12 months, depending on shade and moisture. Moss typically dries and darkens within 6 weeks of the first rainfall, with wind and weather gradually clearing it from the roof.

This service does not include physical moss removal. For quicker visual results or thick moss coverage, ask about our Moss Removal by Soft Wash & Brush. We make it easy to stay ahead of roof damage—so your home stays strong, clean, and protected year-round.
