John Robinson & crew was a pleasure to work with: very professional, respectful & competent. They kept me informed of their work schedule at all times & even went the extra mile to address a vent issue that I did not know I had. I would highly recommend using Allstar Roofing for their quality of work & making the customer feel at ease answering every question. Very satisfied.

Had Allstar Roofing redo the entire exterior,(hardie board) roof, and gutters of our home and the results were great! Very professional and organized. Whenever I had a concern or question, my point of contact and project lead, John was an invaluable resource and took care of any issues or questions immediately. I was very impressed with his knowledge and ability to communicate my concerns and wants to whatever crew was working for the entirety of the project. Would definitely recommend and use Allstar Roofing on future projects.

Ryan Chitwood

I was in need of a metal crew that could do very high end copper work and was recommended this company by a major national player that owns a company in Denver, Co. The people at Allstar Roofing were amazing from start to finish, literally. They traveled here during the week for work and were so careful and respectful. Their copper/metal work is as good as I have ever seen. They just completed the most beautiful roof we have ever done for a homeowner. Their communication was fluid and consistent and we had zero issues. For a job with a ticket that size, we needed this to be a smooth process and Allstar Roofing Inc knocked it out of the park for us. Thank you guys!

Our old siding and part of our garage where damaged due to a storm which resulted in our house needing to be completely re-sided and part of the garage roof replaced. We chose Allstar Roofing not only for the quality of their work but their skilled teams knowledge of insurance claims. Bruce truly made this entire process as smooth as possible. We could lot be happier with how our house turned out.

Jacob Rosenfeld

We just hired Allstar Roofing to re-side & re-roof my home. We chose James Hardie, Board & Baton siding. The Allstar Roofing team was awesome, from my sales contact, Brad Hironimus, to the installers. Despite the house being originally constructed in the 1960's, it now looks brand new and I expect will further stand the test of time. The foreman assigned to our job, John Robinson, was exceptional. He was extremely responsive and always arrived on site with a great attitude. Whenever I had questions or concerns, he was easy to reach and successfully drove the team into delivering a fantastic result. I would definitely refer the Allstar Roofing team to anyone looking to improve their home.

We recently had a new asphalt roof installed on our residence here in Wisconsin. Mr. Pohlman and his crew were professional, timely, and exacting in the quality of their work. The project started and ended on time with no issues. Our property was left in the same condition as when they started. Mr. Pohlman was always available by email and personal cell phone for any questions, and personally on site. Overall, an excellent experience all the way around. Very rare these days.
