Today, we had our two year maintenance treatment ...amazingly there was virtually no moss growth in the past two years which really shows how effective their treatment is! They also cleaned the gutters and washed the skylights as part of the maintenance plan. Their employees were courteous, super friendly, and eager to answer all my questions.

Thomson did a fantastic job removing the moss from our roof. Our roof looks great! The clean-up was great. They did the work quickly and thoroughly. I chose Thomson Roof Treatment Moss Removal company because of the reviews I read. I'm so glad I did. On a scale of 0-10 you did a 10+ star job! Thank you for providing us with such excellent service!
