I was a bit skeptical at first, considering the fact that I recently moved into the DMV area, but I called Sim Roofing for some sidings installation and was very satisfied with their quality of work. They came and gave me a great estimate at a competitive price, they are very friendly and worked with me whenever I had questions about the job being done, and kept me in the loop. I am very pleased, both with the sidings they installed and the service they provided. I would recommend Sim Roofing to anyone who is in the market for roofing, sidings, and gutter services.
