Customer Reviews

"Ty and his team did an outstanding job from the first visit, bid quotation and most importantly the installation. We contracted with Thiel Roofing for a new roof, new gutters and new downspouts. The entire installation was done on time, on budget - priced very competitively, daily clean up, with all my questions answered on the spot. A stunning job by local craftsmen. Get a couple of competitive quotes for your job but then select Ty and Thiel Roofing as the 'best in the business' for roofing, repairs, gutters and downspouts. Bob K."
"Ty came out and took some pictures of water damage/ siding issues and told my wife he would email me in a day or two to explain what's going on what needs to be fixed. 3 weeks later I never heard from him I've called and emailed many times with no answer.. I'm guessing if he sees the opportunity to rake your home owners insurance for a big job u might hear back from him but anything else good luck! Stick to a bigger company who actually calls back and follows up professionally he wasted my time and that delayed my problem being fixed and more water damage."
"Recently had roofing / gutter work done on our house due to the hail and storms. Ty was incredibly up-front, honest, fair and an absolute pleasure to work with. He and his crews were great. Very communicative throughout the process and explained everything very well when we had questions. When completed for the day, they cleaned up great as well. I absolutely recommend getting in touch with Thiel Roofing if you ever have the need for repairs/replacement to your roof!"

- "I called Ty to come out and provide us with an estimate on a roof repair. He came out was very informative and was able repair the roof where needed. Other roofing companies tried to talk us into a new roof. I would highly recommend Thiel roofing for any repair on your roof large or small!"
- "Ty Thiel of Thiel Roofing is a class act! He was responsive, followed through on all requests in a timely manner and sent out an efficient crew. They truly didn't miss a beat and set excellent client expectations! I would highly recommend!"
- "Not sure what the person who gave this company a 1-star review was thinking. If a roofing company is super busy that's a GOOD thing right? My experience with Thiel Roofing has been exactly the opposite. We've had repairs done, and recently had our entire roof replaced by them. ZERO complaints. Ty was extremely professional as was his crew. He gave me a timeline for when the work was to be done and stuck to it. His estimate was bang on. You can go with a large corporate roofing company and be treated like just a number, or go with Thiel and be treated like royalty. I recommend them to all my clients."
- "Ty does incredible work. I consider myself fairly diligent and thorough and Ty exceeded all expectations. His crew was hard working and left my yard neater then when they came. Roof looks incredible. 5 stars around."
