Factors That Impact How Much It Costs To Clean A House Roof
Several variables can affect your final bill. Let’s go over the most important ones:
1. Roof Size
Obviously, the larger the roof, the more time, labor, and materials are needed. Most contractors charge per square foot. A 2,500 sq. ft. roof will cost significantly more than a 1,200 sq. ft. roof.
2. Roof Type and Material
Different roofing materials require different cleaning techniques:
- Asphalt Shingles: Usually soft-washed to prevent damage
- Tile Roofs: May need special solutions to remove mold
- Metal Roofs: Easier to clean, often less costly
- Wood Shakes: Require gentle methods to avoid wood rot
3. Pitch and Accessibility
Steep or high roofs are harder and riskier to clean. Expect higher prices if special safety harnesses or scaffolding are needed.
4. Severity of Dirt, Mold, or Algae
If your roof has heavy moss buildup, deep stains, or hasn’t been cleaned in years, more labor and stronger chemicals will be needed—raising the cost.
5. Location
Labor costs vary across the U.S. For example:
- Urban areas (e.g., New York, L.A.): $800–$1,200
- Suburban/rural areas: $400–$700
