Mr. Sullivan cleaned our roof that had not been maintained in 28 years. The roof appeared almost black, but after the cleaning the shingles were a beautiful light brown color. It really brightened out home. Knowing that the deterioration was stopped with this cleaning was wonderful news. I love my shake shingles and am so thankful for Mr. Sullivan's service to keep them healthy and long lasting for years to come. I feel the cost is a wonderful deal for what you are doing to preserve a beautiful roof. Mr. Sullivan was right on time and came all the way to Kansas City within just a few days of my initial request for an appointment. We was very professional and left our property better than he found it. Thank you, Mr. Sullivan!!!
