Great job done by Brandon and his crew. In and out in one day. The roof looks wonderful. Cleanup was A+. I also want to thank Tyler who was very helpful and reassuring in making my decision to have the work done. Thank you CRS! -

We can’t say enough good things about CRS and Louie! When our new roof was damaged by a fallen tree, Louie responded promptly and worked tirelessly—navigating icy conditions, leaks, and unpredictable weather—to ensure we didn’t have to … More wait until spring for repairs.
He made multiple visits - removed ice and snow, replaced metal paneling, roof decking, shingles, metal flashing, fascia and more, all with expert craftsmanship. Not only was the repair done professionally and quickly, but our roof looks even better than before!
Pricing was fair, and we’d happily trust Louie and CRS for any future work on our home.
Highly recommend and ask for Louie as your sales representative - he will take great care of your project! -

Our experience with CRS was very positive and our roof looks great. We contracted with them to replace the roof on the home we bought before we moved here. Taking on that project from across the country was uncomfortable, but our sales … More rep, Marshall, went above and beyond to answer all questions and make us feel as comfortable as possible. He even responded after work hours and over the weekend. Then when the crew started to work on the roof the project manager called us to introduce himself by phone and suggest a change/ improvement to the rain gutters. We are very happy customers and we recommend CRS without reservation.
