“I called Dwight and Sons Contracting to get an estimate for a new roof on my home. They sent someone out fairly quickly. Karl came out and explained everything very thoroughly to my family and I and gave us a fair quote. They did everything they promised and more! Excellent service, Karl was just a phone call away throughout the entire process which we really appreciated. I will use them again in the future. Highly recommend!!”

“Dwight and Sons did a great job with our roof! They were easy to work with, professional and efficient. We had to replace the roof and sheathing on a second home and we worked together to come up with the best solution for a difficult roof that would hold up well through the harsh winters. We would definitely work with then again and highly recommend this local business.”
