Roof Cleaning

Safe, low-pressure soft wash cleaning that removes moss, algae, and lichen without damaging your roof or voiding warranties.

Professional Roof Cleaning in Seattle & the Eastside

The Pacific Northwest's wet climate creates the perfect conditions for moss, algae, and lichen to thrive on your roof. Left untreated, these organisms can cause significant damage: lifting shingles, trapping moisture, and shortening your roof's lifespan by years.

At Blue Skies Window & Gutter Cleaning, we specialize in safe, effective roof cleaning that eliminates these problems while protecting your investment. Our soft wash method is recommended by roofing manufacturers and won't void your warranty.

Why We Use Soft Wash Technology

Traditional pressure washing can destroy your roof. High-pressure water strips away protective granules from shingles, forces water under roofing materials, and can void manufacturer warranties.

Our soft wash method uses low pressure combined with specialized biodegradable cleaning solutions that kill moss, algae, and lichen at the root. This approach:

  • Removes organic growth without damaging shingles
  • Kills spores to prevent rapid regrowth
  • Is safe for all roof types including composition, cedar, and tile
  • Protects your landscaping with eco-friendly products
  • Maintains manufacturer warranties

Moss

Thick moss growth that lifts shingles and traps moisture

Algae
