Our Services

When you invite us to your home, we will send a crew to prepare your roof for treatment. This includes manually removing any moss that has accumulated using non-abrasive hand tools to cleanly slice the moss off the roof. 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.

Following roof preparation, Thomson Roof Treatment’s owner/operator, Doug Finnigan, will attend your home to personally apply the treatment. Doug has been working on roofs for more than 20 years, and has mastered the skills and knowledge necessary to safely and efficiently provide the best possible care for your roof. He will apply 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. Our formula is environmentally friendly, does not bio-accumulate, and will not harm plants or animals. Rain will aid in rinsing away some or most of the dead growth and grime from the roof over the 8-12 months following treatment, leaving you with a roof that looks like new.

In most cases, we guarantee that your roof will remain moss free for 24-30 months on asphalt / duroid / fiberglass roofs, and 36 months on wood roofs, or we will return to make sure that you are satisfied, at no cost to yourself. Victoria’s temperate climate, and the geographical situation of some houses can promote accelerated moss growth. We assess each roof individually, and will provide you with the most accurate warranty we can, based on our many years of experience. In all cases, the warranty is limited to one year where trees hang near the roof.
