 The only complaint I have is when I have J&B do my roof in another 30 years or so, is Dave their sales man (a great guy) would not guaranty I could get the same great crew I had this time. They did a fantastic job. Much better than the last roofing company did. A nice bunch of guys. Did a very nice job cleaning up. I'd give them 10 stars but 5 is the limit. If you need a roof done this is the company you want to do it. One more point I need to make. The guys that did the chimney flashing are artists. I went up on the roof when they were done and was very pleased with not only the roofing job but the sculptured sheet metal work. It's kind of a shame it's on the roof and not hanging on the family room wall :). You get the point. Hire em. You'll like em. 
 We live in a historic designated neighborhood and recently had our 30 year wood shingle roof replaced with another wood roof and new gutters. From Day 1 of the project to the final day, the entire team was responsive, professional, and very competent. When some minor changes were proposed by us they quickly and effortlessly complied. After going through this experience with J&B, I would highly recommend them to anyone considering a roof and gutter replacement, whether it be a simple or complicated project. 
 J & B did an amazing job from start to finish. The initial meeting at my home took place exactly at the time that was agreed upon and Scott was thorough in his explanations and transparent about costs. When the time came to begin the project, the team that showed up was friendly, professional and timely in getting the project done. The cleanup afterward was such that it looked like they hadn't been there at all. The roof looks great, there were no surprises and Scott came by to inspect the work and explain the warranty upon job completion. I would highly recommend them.
