Best Roof Cleaning in Phoenix AZ

I have been using CHS for almost five years and I cant say enough great things about their staff and service! One summer my AC was out of Freon and it was 90 degrees in my house upon returning from vacation. It was Sunday and my home warranty company couldnt get anyone out so I call CHS and they came over immediately! They were such life savers and fixed my issue while my small children cooled off in the pool. Thanks CHS!
