Roof Moss Removal

Why Your Seattle Roof Needs Moss Removed

Moss isn’t just an eyesore. On Seattle roofs, it’s a real problem. Our damp climate and frequent shade create the perfect environment for moss to thrive. Left unchecked, moss holds moisture against your shingles, leading to premature decay, wood rot, and leaks. Many homeowners try DIY solutions like pressure washing, which can strip away granules and void your roof’s warranty. We provide a safe, effective alternative.

How Our Roof Moss Removal Works

Our process is designed to remove moss safely while protecting your roof and complying with local environmental regulations.

1. Inspection: We start by assessing your roof’s condition, moss coverage, and any underlying issues.
2. Soft Wash Application: Using low-pressure soft washing, we apply an eco-friendly cleaning solution that kills moss and algae without damaging shingles.
3. Gentle Removal: Moss is carefully brushed away once loosened, avoiding any abrasive scrubbing.
4. Rinse and Cleanup: We rinse the roof gently, capturing and managing runoff according to Seattle stormwater codes.
5. Prevention Treatment: After cleaning, we apply a zinc-based moss prevention treatment to slow regrowth.

For roofs with heavy moss or those needing extra protection, we also offer:

• Roof Moss Treatment (periodic maintenance between full cleanings)
• Moss Prevention Coating (longer-lasting barrier against regrowth)
