John was super responsive, extremely knowledgeable, and had a great sense of humor. We received 3 quotes. He was the only one that actually got on the roof to check for rot and other stuff you can’t do with an aerial view. They added vents, and replaced our plastic vents with metal. Apparently you’re not supposed to use plastic, because the squirrels were chewing through ours. His crew were all great guys too. They hardly took breaks and were very grateful when I brought lunch, and cold drinks. He kept within his quote, and had supporting documentation for all that was done. We will be using John for our windows next. It's nice to know a trustworthy contractor.
