Step 2
Application of professional moss treatment.
Step 3
Gutter cleaning to remove moss debris.
Because Vancouver Island has a wet coastal climate, moss naturally returns over time.
While professional treatments slow regrowth, no roof treatment can permanently stop moss.
Most roofs benefit from:
• Full moss removal every 3–5 years
• Periodic preventative treatments
Regular maintenance helps keep moss manageable and extend the life of your roof.
Many homeowners choose to schedule preventative maintenance after moss removal.
Our optional roof maintenance plan includes:
• Follow-up roof treatment the following year
• Roof inspection
• Early moss prevention treatment
This helps slow moss regrowth and maintain the roof between full cleanings.

Is roof moss removal safe for shingles?
Yes. We use manual removal and treatment methods rather than high-pressure washing.
Do you pressure wash roofs?
No. Pressure washing can damage shingles.
How often should moss be removed?
Most homes benefit from moss removal every 3–5 years.
How can I keep my roof moss free?
Yearly roof treatments limit moss growth and the need for manual removals. Which is much more cost effective than waiting for the next manual removal.
Do I need gutter cleaning at the same time?
Yes. Moss removal fills gutters with debris.

The men worked quickly and were very accommodating in terms of getting into backyards that were not exactly accessible in order to clean the eaves troughs. We also had our windows washed. So nice to see through them again without a layer of dirt. Excellent service all around.
