Ben and his crew have done work for me a couple times. They did a repair on a roof on a house we were selling and then replaced the whole thing on the new house we bought. Whether the job was big or small they were top notch across the board. The craftsmanship is unquestioned and I cannot say enough positive things about working with him.

Ben assessed my roof for potential damage, found none and then was kind enough to add some sealant to a few exposed nails for no charge. He clearly has a heart for high quality workmanship, explaining that a little attention to these important details now would prevent significant issues in the years ahead.

I am highly recommending Ben and his crew, they did a great job on our roof replacement. Ben was a pleasure to work with, a professional in every way. His crew keeping the area around our home cleaned up on a daily basis even after long days on the roof. And, the roof looks great just in time for winter weather!!
