Moss free roofs from Victoria to Cowichan Valley

We specialize in moss removal that will help preserve the life of your roof while improving the look of your home. The only treatment of its kind, we have been providing service to lower Vancouver Island since 1980. Our work is effective and guaranteed in writing.

Our Mission

Our mission is to provide quality roof care that preserves the life of your roof and improves the look of your home.


includes manually removing moss that has accumulated. A blower is used to remove loose debris from the roof and gutters, and then to tidy up the grounds before they leave your site.


involves applying Thomson’s unique non-toxic soap based solution, which neutralizes any moss, lichen, mould or mildew present. We use a gentle, saturating method of application; we do not use pressure washing, which can damage your roof. 


guarantees that your roof will remain moss free for a specified number of months or we will return to make sure that you are satisfied, at no cost to yourself. We assess each roof individually, and will provide you with the most accurate warranty we can.

The staff were thorough in cleaning and prepping the roofs for the treatment, cleanup and very easy to deal with. I have received several positive “reviews” from other owners in the Strata. This should help extend the life of our roofs. Thank you.

I had initially called two other companies I found on line, the first made appt for estimate and never showed up, called a week later and didn’t show up again!

I was impressed from the beginning when Steve showed up slightly ahead of the arranged time and got set up easily. Not only was the roof work done well (as far as I can see) the clean-up was just as carefully done – not to be taken for granted.
