What our customers
say about us

Brian and Kyle were very professional, prompt, and easy to work with. They communicated with me every step of the way, my roof looks great, and the property was cleaned up well. I couldn't recommend their services more, and will be sending my friends and family their way.
Michael Templeton

Brian helped guide me through a roof replacement due to hail damage. He was quick, responsive, and patient with attention to detail throughout the process. Would recommend!
Spencer Mainous

I had my roof and gutters replaced due to hail damage. I can’t recommend Brian and Horizon roofing enough! Brian was extremely professional, provided excellent communication, and made the entire process smooth and easy. Brian was truly a pleasure to work with and is a consummate professional. The Horizon team did outstanding work and I was extremely pleased with the final product. Our new roof and gutters look great. All dealings with insurance were seamless and hassle free. If you need work done, I HIGHLY recommend reaching out to Brian and letting Horizon take care of your project. Five stars across the board ️
