moss and algae uncleanVancouver has an average of 166 rainy days per year, allowing moss and algae to thrive in our beautiful (but wet) city. While rain is great for our lush environment, it’s not so great for our homes because it causes moss and algae to build up.

The main factors of moss and algae growth are moisture, shade, and close proximity to trees and debris. While these conditions are unavoidable in Vancouver, we can certainly prevent damage to our property by washing all surfaces regularly.

Most at Risk Areas for Moss & Algae

Northern Exposure

North facing surfaces are more susceptible to moss and algae growth because they receive less sunlight and moisture takes longer to dry.


Areas that are heavily shaded by overhanging tree branches and shrubs will be the perfect environment for these tiny organisms to grow.

Out of Sight – Out of Mind

roof clean dirtySince most of us don’t spend that much time on our roofs (unless you have a rooftop patio in which case consider yourself very lucky), we tend to forget about how things are doing up there.

Especially if you cannot see the top of the roof, it will be difficult to determine what growth has accumulated. Moss on roofs can become a big problem if left untreated. It can displace roof shingles, introduce moisture (and subsequently cause rotting issues) and cause mold growth that can easily spread to walls and other areas in your home.

Prevention & Maintenance for Moss & Algae

Yes, moss and algae can be a big headache. But don’t fret! Following a cleaning maintenance plan is the best action that you can take.

Pressure Washing

We generally recommend that you pressure wash your home (or soft wash, depending on the surface) at the first sight of green and/or black discolouration, as this is an early sign of moss and algae growth. So keeping a close eye and regular inspections around your property is very important.

Paver patios, driveways and walkways are especially prone for build up in. It can be a tedious task to get the grime cleaned out, especially if this is left to build up for a long time.

Roof Cleaning

Roof cleaning can be tricky work, especially if it the roof is slick and covered with moss. We recommend to clean the roof on an annual or bi-annual basis.

Once the initial roof cleaning and the application of our proprietary roof cleaning solution (to kill moss over the course of 1 to 2 months) has been completed, we recommend booking a roof cleaning and gutter cleaning appointment 2 to 3 months after the initial roof cleaning.
