How much does roof moss removal cost in Metro Vancouver?
Short answer
Roof washing and moss removal in Canada typically costs about $250 to $600 for an average house. Roofs with heavy moss, steep pitches, two or more storeys, or a moss treatment and gutter clean-out added on cost more. In Metro Vancouver's wet climate, most roofs need moss removal every one to two years.

Why moss is a problem
- Moss holds water against your shingles all winter
- It lifts shingle edges, letting rain blow underneath
- Clumps wash into gutters and block downspouts
- Left alone, it can take years off the life of a roof
What changes the price
- How much moss there is and how long it has been growing
- Roof steepness, height and safe access
- Whether you add a moss treatment to slow regrowth
- Whether gutters are cleaned out at the same visit
How Smart Earth Group removes moss
- Hand removal and low-pressure soft washing — never high pressure that strips shingle granules
- Optional moss treatment to slow regrowth
- Gutters cleared afterwards so moss doesn't block them
Common questions
Does pressure washing damage a roof?
High pressure strips the protective granules from asphalt shingles and shortens their life. Moss should be removed by hand and with low-pressure washing.
How often should moss be removed in Vancouver?
Every one to two years for most homes. Roofs shaded by trees may need it every year.
When is the best time for moss removal?
Late spring through early fall, when the roof is dry enough to work on safely and treatments can soak in.
