Arick Middeke was awesome to work with! He made sure every part of the process was complete to our satisfaction. Horizon did an outstanding job for us! It was a joy to work with Arick and his team!!!

Arick did an amazing job of managing this job from start to finish. I was impressed with his attention to detail and how clean the home was left. They did an efficient job--and it wasn't an easy project due to the urban footprint of the home. Additionally, he honored an unusual disposal request rejected by other bidders that won the bid.

I worked with Arick on my roof after storm damage. Super smooth process, no notes!

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! Updating to add that Horizon also replaced the siding and gutters recently (years after the roof). Still in business, still producing great results!

Brian was outstanding to work with throughout the entire insurance claim process. After my initial hail damage claim was denied while working with another roofing company, my insurance agent connected me with Brian at Horizon Roofing. From the very beginning, he was knowledgeable, responsive, and willing to go the extra mile.
Brian took the initiative to help get my roof re-inspected, worked directly with the insurance company, and ultimately helped get my claim approved. He made what had been a frustrating experience much easier to navigate and kept me informed every step of the way.
Based on my experience so far, I would highly recommend Brian and Horizon Roofing to anyone dealing with storm damage or an insurance claim. I’ll update this review once the roof replacement is complete, but I’m extremely impressed with the service and professionalism I’ve received so far.

6/16/26. Fulton from Horizon Roofing and Exteriors came out to the house today regarding my roof. Right from the start, I was impressed with his followup. So often you have to sit around and wait for somebody to show up, but I knew exactly when he was coming and I appreciate that. I told Fulton my concerns, he went up on the roof, then came back down with pictures and advise on what needed to be done. I felt very comfortable with his suggestions. Fulton is definitely an asset to Horizon Roofing and Exteriors. I look forward to working with them further. Thank you.

Fulton was my project manager. I can’t say enough great things him. From start to finish, he was easy to work with, a great communicator, and followed up on a timely manner. The guys did a great job on the roof. They made sure I didn’t get any nails in my pool. . But most importantly, my roof looks great! Would definitely recommend to anyone needing a roof replaced.
