"8 June 2024 Bordner did the roofing on our home three years ago for the previous owner. The roof has failed in multiple places, leading to part of the structure needing to be demolished (they don’t know how to install EPDM) and other parts of the roof to rot out entirely. When the problem was first noticed to be attributable to the recent ‘professional’ roof work, I asked to meet with a Bordner representative on site to review the leaks. I was fobbed off. I was told they were very busy and it could be a month. I asked again and said this was unacceptable to which they said they would be out in a week. As the damage was so bad and the site progress was being adversely affected, I said I would just hire someone else to replace their work and send them the bill. They then became available to meet and insisted they would do the repairs, if any repairs were to be done by them (yet ten days later no one had even been on the roof from Bordner). I was put onto one of their director’s Kyle whom I spoke with and emailed back and forth. He was not very forthcoming with information. He tried on multiple occasions to throw people not involved in the roofing under the bus , including the framer (who did 1,000’s of projects with Bordner). I later learned the framing subcontractor refuses to do work with Bordner because of their business practices and past experiences. They sent a PM to the site a several days later. A nice chap. We had scaffolding up around the house. I offered to let him up on it to see the roof, but he declined, so I showed him photos whilst standing just under the roof. In reviewing photos we also discovered the chimney flashing was incorrectly installed. I followed up the following day with Kyle to see what was going to be done to fix the roof. He again fobbed me off and said I may hear from a different director/owner. I asked who that person was and Kyle refused to tell me. I find it ironic that the marketing director, Kyle, deals with warranty claims. This speak volumes to how the business is run. After a week and much chasing, I finally got in touch with Sam Fleenor, a Bordner director. I was clear with him that time had run out for making excuses that repairs needed to be made or he would need to reimburse for the work. He again did not take responsibility and said someone would come out next week to look at it (after the previous week someone came out met me on site but did not want to look at it). With no timeline for repairs or resolution is site, we had no choice but to hire someone else to do the work to avoid more damage to the structure. Sam was to contact me Monday with how the roof issues would be resolved. Monday came and passed and no sign of Bordner via email or phone. I contacted them at five this evening to see where they were with our claim. Sam replied and said they drove by and it looked like we made the repairs. He offered to add more silicon to their poor chimney flashing, but nothing else. After being part of completing a roughly $20k roofing job three years ago which caused tens of thousands in damages, Bordner offer only to bring a tube of caulk. As an architect of nearly three decades, I have never seen such poor workmanship and belligerence from a contractor. Highlights of their workmanship include chimney flashing caulked to the sloping side of the chimney (should be stepped and cut into mortar joints), EPM membrane screwed onto plywood so that water passes straight through and destroys the structure, water p****** out of soffits, etc. You learn the most about a company when something goes wrong. Things went terribly wrong and Bordner has damaged our home with costs exceeding $20k. They now say the 3 year old roof is out of the 10 year warranty. 3 July. Bordner refused to get up and look at their roof issues. Now they claim it’s ‘unfortunate’ and they have learned. Imagine what their response to you will be when there is a problem. 16 July Still no resolution from Bordner. Warranty is useless and Bordner insurance is non-existant. We are out over $40,000 in damages…"
