Johnny, Joe, Stephen and Peter were fantastic. We had a standing seam roof installed by them March 2026 and boy does it look good! … Our roof will look great for a long time to come. Thank you very much Johnny and team!
-
God bless Johnny. I knew him as my neighbour and my brother in Christ. He did a marvelous and spectacular job in installing a metal roof for my house. He is also professional and faithful to his work and his clients. I would recommend him to any one interested in getting their metal roof done.
-

We just had our house and garage done by Guenther Roofing. Johnny was great to work with and the roofing crew did a great job. It was a great experience from beginning to the beautiful end. We will definitely recommend Guenther Roofing to anyone wanting a new metal roof.
-
We recently had a metal roof installed, and couldn’t be happier with the results! The team was incredibly professional from start to finish. They showed up exactly when they said they would, which is rare these days. The quality of the product is amazing — far beyond what we expected — and it was reasonably priced compared to other companies we looked into.
-
Our roof is so beautiful! We got a lot of compliments from our neighbours. We absolutely recommend GUENTHER METAL Roofing, it’s a 5 star! The quality of their workmanship is remarkable!
-
Johnny and Levi were very thorough and careful in their work on our house and garage, and I highly recommend this company. Very conscientious and knowledgeable, and they care about people. We are very pleased with the result and the price was very competitive even compared to the quote from an asphalt roofer. Thank you, gentlemen!
