Location: Omaha, Nebraska. We contracted with Derek Liebert and Attic Solutions to have our roof re-shingled. Our roof has leaked three times since his company worked on it. He addressed two of the issues. However, on the third leak, when the flat roof leaked and water ran into the garage, after inspecting it and pointing out that it was the fault of his crew and saying he would fix it, Derek made repeated promises that he didn't keep. It has been nearly 3 months and the roof has not been repaired as promised. Derek goes through long periods of not answering his business phone and not returning calls. We have finally had to contract directly with another company to fix the flat roof. After several phone calls and messages left on his voicemail, Derek agreed to reimburse us the amount for which he agreed he was responsible. He said he would send a check on Friday, Dec. 17th. Ten days later we still have not seen a check, and again Derek is back to not answering his phones and is not returning calls. We have filed a complaint with the BBB.
