We contracted with J & M construction to replace two porch roofs on our house. The roofs were to be metal, standing seam, installed to manufacturer's installation instructions. On 9/15/21 we signed a contract and gave him a now cashed check. He said he would start work in two weeks, once the metal arrived. His crew stripped, papered and sheeted the roof on 10/27/21. His crew did significant damage to the surrounding roof and guttering system. The roof leaked immediately. He tried unsuccessfully 3 or 4 times to stop the significant leak that has caused boards to warp and puddles to form on the porch. He would show up at odd hours, sometimes working till 9:00 PM. These leaks continue today. He returned with the metal on 12/3/21. He installed some of it. On 12/17/21 he installed the "valleys." I was concerned it was not installed correctly, and he used the wrong tool to cut the metal. On 12/20/21 I spoke with and sent photos to the manufacturer who said it was incorrect and sent an installation manual. In looking at it, I noticed he had used sheeting that is too thin. His supplier told me that there had been two orders, the first was in the wrong color. He never showed for a meeting scheduled for early morning on 12/21/21 On 12/22/21 we spoke at length. We discussed multiple items on a checklist I gave him, including the need to use butyl tape. I also gave him the pertinent pages, annotated, dealing with the "valleys." I also emailed him the entire 22 page manual. In the interim he did more work, again not as directed. I questioned him repeatedly about his using Butyl tape. He said he would fix it, but continued to use the wrong product. The metal has been bent, scratched, walked on, and warped. I had multiple reputable people look at his work, they concur that it is not installed correctly. As of 1/13/22 it still leaks, the gutter is still not fixed. I have had to hire someone to finish the job, as he would not follow the manufacturer's instructions. read more
