  • "The entire experience was great. Randy Biddle was the salesperson representing the company, and provided hands-on excellent service. He was at the project daily, not only talking to me and my wife, but the entire crew. He brought them waters and Gator-Aid daily and fostered a great team atmosphere. While the re-roofing process is a bit chaotic, the entire crew was always smiling and laughing. Nice to see these days. I would and have recommended Bob Jahn's Roofing to all who are interested. They are a true testament to a long-term, successful business that cares for their employees and customers."

  • "Buyer beware of Bob Jahn’s Roofing, CSLB#400569. Our roofing project that began on April 4, 2022 still remains incomplete as of 5/3/22. We live in a 76-year-old home with major dry rot damage that needed to be fixed prior to roof install. Bob Jahn’s Roofing neglected to recommend needed repairs on dry rot once the roofs were open, and has refused to absorb any of the cost for this mistake ever since. In addition they have been harassing us for payment and they have issued a pre-lien on our home while we have been trying to get this matter resolved. On Monday, April 4, 2022 after the demo/tear-off crew finished midday (around 12 PM), no representative of Bob Jahn’s Roofing walked us through the property in order to discuss the dry rot that needed to be fixed and/or replaced in order for the project to be completed per contract: “DRY ROT: If there is dry rot, a change order will be issued, and all will be replaced after approval from customer.” No “approval from customer” was sought on either Day 1 or Day 2. Instead, on Monday, April 4, 2022 a vague and incomplete change order was issued by Bob Jahn’s Roofing. We signed Change Order 1 for thousands of additional dollars on the morning of April 5, 2022 in good faith, assuming that all dry rot would be repaired prior to the installation of the roofs. It was not. The roofs were installed and the dry rot was not repaired. Bob Jahn’s Roofing did not repair essential rafter tails prior to the installation of the gutters. In fact, when the gutter installation team arrived they said they could not hang the gutters on such damaged rafter tails—“it’s common sense,” they said pointing to the soft, damaged wood—and left the work site within 15 minutes. On Tuesday, April 12, 2022, a Bob Jahn’s Roofing team member came on site and provided a detailed accounting of what was completed and what was not completed by the team in order to fulfill its obligations under contract, as well as under Change Order 1. On April 13, 2022, we sent a detailed email (“OUTSTANDING roof repairs prior to gutter install”) along with a Google Drive full of photographs and videos detailing the damage that was still outstanding. Instead of seeking to fix their mistakes and absorb the costs, Bob Jahn’s Roofing instead sent another change order requesting thousands of dollars more to complete the project. On Friday, April 22, 2022, Bob Jahns, the owner of Bob Jahn’s Roofing and another representative performed a walk-through inspection of our dry rot. Regarding all of the dry rot on the detached garage, Bob Jahns said that all that was needed in order to finish the garage was “some pressure washing and painting.” Some pressure washing and painting?! Bob Jahns ignored the fact that on April 12, his team had marked with an “X” all of the rafter tails and rake boards that had dry rot and needed to be fixed—there are 14 rafter tails and 2+ rake boards that need to be fixed. At this point, since Bob Jahn’s Roofing has failed to perform under contract, and has failed to adequately complete Change Order 1, we are seeking to finish roof repairs from another company and seeking to recover costs from Bob Jahn’s Roofing. While Bob Jahn’s Roofing has agreed in early May to cover SOME costs that were a result of their error, on May 13, 2022 the home failed to pass inspection with the City. Given that failure, Bob Jahns Roofing still refuses to cover all the costs that are their responsibility in order to close the permit and pass inspection. If this matter cannot be resolved in a satisfactory manner, we will be opening a complaint with the Contractors State License Board and the Better Business Bureau."
