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.

After years (I’ve lived in this house 25 years) of struggling with different methods and companies to eradicate the moss, Thomson finally did it, and I’ve stayed with him ever since.

Prompt, professional and curious service. The product works amazingly. Since the first application we had has “no” moss on our roof. Prior to your application we had tons of moss. Tks for that.
