"M&J Roofing is such a pleasure to work with; honest, fair, responsive and reliable. They put a new roof on our home a number of years ago (complicated job that turned out great), and recently stopped by for some quick repair work on a shed – immediate response and no charge! Couldn’t recommend them more highly!!"

"Our roof needed work. 25+ years old we were due for a new one. I liked the estimate that I received from home genius. Fair price/decent informative presentation of materials. During the roof getting done, we decided to do gutters as well. All crews performed great and were very punctual and professional. Masters of their craft. We love the color we went with and would recommend home genius to those looking for roof and gutters."
