“We HIGHLY recommend Andy Jansen and his crew. We have had Andy’s Roof Shampoo clean 2 of our homes, our recreational building and 3 of our lakefront rentals on Tee Lake. It was amazing how clean the roofs came out. The one roof had green moss growing on about 25% of the roof surface and we had actually priced out a new roof. When Andy came to look at it, he said, “Let me try to clean it first, and if I can’t, then you don’t owe me a dime.” So he did clean it and it looked like brand new!!! Saved us about $15,000 for a roof that wasn’t necessary. Wished the gentleman that gave us the estimate for a new roof was just as honest as Andy is. He is always honest and very trustworthy. He is very professional and respectful to your home and property.”
