“A clean roof isn’t just about curb appeal—it’s about protecting your biggest investment.”
Why Roof Cleaning Is Essential in Seattle’s Climate
Seattle’s rainy weather encourages the growth of moss, algae, and lichen, which can cause significant roof damage over time. Regular roof cleaning helps:
✅ Prevent Moss & Algae Growth – Stops moisture retention that leads to rot and decay.
✅ Extend Roof Lifespan – Removes harmful debris that can degrade roofing materials.
✅ Improve Energy Efficiency – A clean roof reflects heat more effectively, reducing cooling costs.
✅ Boost Curb Appeal – Instantly enhances the appearance of your home or business.
✅ Avoid Costly Repairs – Regular maintenance prevents small issues from becoming expensive problems.
According to the Asphalt Roofing Manufacturers Association (ARMA), regular roof cleaning can significantly extend the life of asphalt shingles by preventing algae and moss buildup.
How Much Does Roof Cleaning Cost in Seattle?
The cost of roof cleaning depends on several factors:
💰 Roof Size & Type – Larger roofs or delicate materials like tile may require more time and care.
💰 Level of Dirt & Moss Buildup – Heavily soiled roofs may need additional treatments.
💰 Roof Pitch & Accessibility – Steep or hard-to-reach roofs can increase labor costs.
