How Often Should I Schedule Roof Cleaning?
Every 2 to 3 years for most homes. Sooner if the firs are shading your shingles.
Every two to three years works for most Vancouver homes. Heavy shade, fir trees overhead, or a damp north-facing slope can shorten that to yearly. Regular cleaning stops moss and algae before they root in and shorten your roof's life. We can look at your roof and set a schedule that fits it.
Why Vancouver Roofs Grow Moss So Fast
Our winters are long, wet and gray. Shade from tall firs keeps shingles damp for months, and fallen needles trap even more moisture. That's a perfect nursery for moss. Watch for these signs that your roof is due:
- Green fuzz along shingle edges, especially on the north slope
- Black algae streaks running down the roof
- Fir needles and debris piling up in the valleys
- Shingles that look lifted or bumpy from moss growing underneath
Clean It, Then Keep It Protected
Cleaning is step one. Our moss removal uses a gentle soft wash that clears growth without stripping granules off your shingles. Step two is protection: a Fresh Roof treatment rebuilds the oils in aging shingles so the roof sheds water and resists new growth.
While the crew is up there, it's the perfect time for gutter cleaning too. The same needles that feed roof moss also clog your downspouts. Bundle the services and save.
The Short Answer
