I recently had my flat roof reroofed by Houston Commercial Roofing and Coatings. The owner came out to provide the estimate and spent time on top of my roof reviewing the condition. I had several companies come out to provide me estimates and the ones who never walked on my roof were not even considered. He provided me with a lot of information about the condition of my roof and options to consider. His estimate was emailed to me in a couple days and was very competitive.
