We had skylights leaking. Other contractors came over, looked at the outside and gave a quote for replacing or repairing the skylight--a generic fix. same thing for all skylights. Steve, however, of Roofer911 looked at the skylights from the inside, the outside, went on the roof, and used an infrared camera to locate any water inside the walls. He diagnosed two different problems for two different skylights and noted that one problem was being caused by a gutter that was not sloped properly which sent all the water down inside the siding of the house. NOT a generic fix! He was very thorough and explained everything that he was going to do and why it should be done to protect the structure of the house. His workers were efficient and professional and friendly. Great job all around!
