Note

Moss and algae left untreated can cause thousands in roof damage. Spending a few hundred dollars now can save you from a $10,000+ roof replacement later.

What Affects Roof Cleaning Prices?

Several factors influence the cost of your roof cleaning:

Roof Size: Larger roofs require more labor and time.
Roof Type: Cedar shake, metal, tile, and asphalt all require different methods and care.
Moss or Algae Growth: Heavily infested roofs may need chemical treatments or more time.
Steepness and Accessibility: Steeper or hard-to-reach roofs are more labor-intensive and require additional safety equipment.
Debris Removal: Excess pine needles, branches, or gutter clogs may increase the total price.

Is Roof Cleaning Worth the Cost?

Absolutely. Here’s why roof cleaning is one of the smartest home maintenance investments:

Extends Roof Life: A clean roof lasts years longer.
Improves Curb Appeal: Makes your home look well-maintained and increases resale value.
Prevents Water Damage: Moss traps moisture and causes leaks and rot.
Saves You Money: Prevents costly repairs or full replacements.

In Bellevue’s damp climate, roofs should be professionally cleaned every 12–24 months, or sooner if moss is visible. Many homeowners also schedule a quick annual checkup to stay ahead of buildup and catch minor issues early.
