The company works very promptly, accommodated to short term and did an excellent work, great clean up around the property after the roof and gutter cleaning and treatment. Great attention to detail: while cleaning a small roof over the kitchen area, the person who was doing the work, also cleaned the moss off the small kitchen bay-window. This is the task that I was often wondering how to do or whom to ask to help me with. I was very nicely surprised when I heard that scraping sound, realizing that the worker noticed this moss and cleaned it off. IT MADE MY DAY! Thank you very much! I am looking forward to have Thomson Roof Treatment continue to help with the roof maintenance of my house.
