The cost of roof cleaning in Quebec varies considerably depending on several factors. Here is a transparent guide to help you understand and budget for this service.
Our pricing grid
- Easy (low pitch): $0.48/sq.ft — low-slope roofs, easy access
- Medium (normal pitch): $0.57/sq.ft — majority of residential homes
- Difficult (steep pitch): $0.65/sq.ft — very steep roofs, limited access
Minimum price is $399 before taxes (GST 5% + QST 9.975%).
What influences the price
In addition to pitch, adjustments apply based on: presence of severe moss or lichens, roof complexity (dormers, multiple angles), site access, and building height.
Beware of prices that are too low
A very low price often hides excessively diluted product (ineffective), absence of vegetation rinsing protocol (real risk), or an untrained technician. The result: a roof that looks clean for 2 weeks then goes gray again in 6 months.
