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.

Preparation

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.

Application

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. 

Assessment

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.
