The treatment is very effective - our roof was not responding to other "stuff"; the very careful hand removal of the moss plus the compound used AND the follow up treatments have been a roof saver for us on the wet coast here. Also, this co. is very good at communicating, so that one does not have to waste a day waiting for the service man to arrive. being in touch all the time really helps to get the work done and they seem to know it!

We live in a forest where it's usually shady and where leaves, pine needles and branches are always falling on our roof. Roof moss is a problem. After contacting them in early 2018, Thomson Roof Treatment arrived on time, cleaned the roof thoroughly, applied the moss treatment and tidied up. In early April, 2019, they came back for a followup, and again thoroughly cleaned a very debris-covered roof, applied another treatment and left the whole place very clean and tidy. They're very efficient, they do good work and never need supervision or direction. Highly recommended.

The crew arrived on time, the work was done efficiently and professionally. The roof looks like new. Would recommend Thompson to all my family and friends. You wont be disappointed.

After having our roof demossed/gutters cleaned, we signed up for their two year maintenance program. We received a reminder in advance of their arrival. Very professional with great cleanup and service.

Excellent service, courteous staff. Thomson Roof Treatment has kept our roof moss-free for over 20 years. Highly recommend the company. Steen Jessen, Oak Bay
