I need a good roofing company in the Chattanooga TN area that can fix a slate roof that a few tiles have slipped a little side ways. The home owner would like them straightened. The roof is not leaking so it is just a cosmetic fix. If someone could recommend a company that works in that area please send them my way. I will be cleaning the slate in the spring after the repairs. I need someone good as this roof is 70 years old and I will not send him the contact info for a shingle roofer that thinks he can fix the issue. I have left messages for a couple of companies and they do not call back. I guess they don't like to work because the customer service sucks.
