THE SHORT ANSWER
How to Estimate Roof Cleaning
A 1,500 sq ft roof with soft wash, moss treatment and 8 labor hours at $45 totals about $1,135.
Price by roof area
Roof cleaning prices by the area of the roof surface. Measure the footprint and multiply by pitch to get the true surface.
- Roof area
- Soft wash vs pressure
- Moss treatment
- Access
Choose the method
Soft wash uses low pressure and chemicals to clean without lifting shingles. Pressure washing is faster but riskier on asphalt.
Moss and algae add work
Heavy moss needs treatment and extra rinsing. Quote a moss surcharge and explain why.
Difficult access costs more
Steep pitches and tall roofs need more safety equipment and time. Add an access charge.
