Hear It Straight From Our Customers

“Such a wonderful company to work with from the start. Professional and informative estimate. Thank you, John! Carlos and his team did an EXCELLENT job on my new roof. They were very professional and thoroughly cleaned my property several times each day for my family and my dogs. Simon and his crew were wonderful with the gutter install and, again, very professional with a thorough clean-up afterward. I can’t thank RoofSmart enough! Greatly appreciate all your hard work and the step-by-step photos provided as well! I would HIGHLY recommend them!”
-Beth Malaykhan


“Absolutely LOVE IT! And thanks so much for getting the project moved up, exceeding my expectations. The appearance & quality of this roof will undoubtedly add value to my home, but most importantly, it will provide us with aesthetic beauty for years to come.
The Solatube is GREAT! I was able to work with Gabriel to get it installed right where we wanted it, we’re really enjoying it.
Thanks so much for helping turn our dreams into reality. Excellent work!”
-Dave Guinn


“For all the little things that we needed to get fixed after the installation, they were literally at our place within hours. Jim has gone above and beyond to guarantee that we are satisfied customers. The 5 out of 5 stars took a little time to earn, but their responsiveness made up for the four stars from some smaller details earlier on the job. I highly recommend Roofsmart to anyone who wants to be treated like family. No big box store feeling here. It’s like family!”
-Scott Schrieber
