Q: How often should roofs be professionally washed?
For homes and businesses in Terrebonne and the Greater Montreal area, we recommend washing your roof every 2–3 years to maintain its appearance and prevent damage. Roofs shaded by trees or in humid areas may need annual cleaningto prevent moss and algae growth.
Q: Why is regular roof cleaning important?
Regular roof cleaning:
- Prevents damage from moss, algae, and lichen that can shorten roof life
- Removes black streaks caused by algae (Gloeocapsa magma) that hold moisture and heat
- Improves curb appeal and makes your property look well-maintained
- Maintains energy efficiency by reflecting more sunlight
- Helps protect warranties that require regular maintenance

Yes. We can schedule roof washing during evenings or weekends to accommodate your availability, especially for commercial properties.

In most cases, roof washing is best done in warmer months to allow proper cleaning and drying. However, we can perform winter roof cleaning in certain conditions to remove moss, algae, or urgent debris buildup.

No. We use a soft wash method—not high-pressure washing—which is recommended by roofing manufacturers to safely clean without stripping protective granules or damaging materials.
