Sullivan’s did my roof cleaning 3 years ago and the roof is still in great shape with none of the previous dirt, mold or mildew that it had before. True to their word, the treatment has maintained just as Bruce said it would. Each year since, they have washed my steel siding and my cedar deck and I am always pleased when the work is done.
