It’s a professional job!Good service , responsibility and quality.

Honest, professional service.

I have known Greg for years. He is Detailed, Trustworthy, Honorable, and has a great work ethic.

I have used GM Systems on several projects all with GREAT success. some of these roofs are 6 or 7 years old and recently had its first small leak on a 4800SFT roof project and the crew was out to repair it as soon as we called them. I would not go anywhere else for service. They came with a good reference and I am proud to give them a good reference.

I have done business with GM Systems several times and they are great to work with. Billy T.

I have found GM Systems to be a very reliable company that we have used on several occasions. Greg and his crew are very good at what they do. The sites were well maintained and clear of debris and clean up was perfect which is very important to our facilities .

Greg Steirwalt did a great job in a very difficult situation. He made the building stable and installed the roof. His customer service was outstanding! I would recommend him.

Greg would be the person I would go to if I needed a new roof on my business! One of the very few people that I know that you can take at his word. Honest and dependable and would go above and beyond to make sure a job is done correctly.

Greg it's a very good guy to do business with you will not be disappointed by him!

GREAT service, highly recommend

Greg is honest and communicates well! He’s always pleasant to work with. Highly recommend.

Our experience with GM Systems was very positive. They responded to our needs in a timely manner. Their work was completed as agreed. We would recommend them without hesitation to anyone looking for roofing work.

GM Systems are great! I spoke with a couple other local businesses who had used their service and they raved over them. They came out as soon as the weather allowed and completed the work much faster than I expected. We have had snow and rain since the repair and there are no leaks, the repairs we received from other companies previously did not stop the leaks. GM Systems is certainly who I will call in the future.

I have known Greg Stierwalt for many years. He has been on the board of my church. Greg also cared enough to serve and be involved in his local community as well. I know him to be a man of character and integrity. Although I haven't had need of his services myself, I would not hesitate to contact him if that need arose.

GM Systems did an excellent job solving and correcting our persistent leaking problems at our office and I would highly recommend them for that service

We highly recommend this company for commercial roofing needs. Always professional, Greg Stierwalt has experience and integrity that is hard to find in the business world today. You can have confidence that he will do a great job for you and your company.

Have used them on multiple occasions have always been happy with the professional and timely service!

Greg has always been professional when I have worked with him. He is personable, responds in a timely fashion and has open communication about the project at hand. It's always a sigh of relief to genuinely trust the people you are working with.

Repaired roof, did a good job, very professional, have used Greg before and very pleased with his work. I will hire him again for future jobs.

GM systems did a difficult three level commercial roof install on an older commercial roof in our town. The roof was installed in a timely manner and was leak free until this fall when we had several ice and snow storms which resulted in leaks. They were very responsive, coming out and repairing the leak and following up to ensure the leak was fixed. Hats off to Greg and his crew!

He and the folks at GM Sytems do exceptional work and it’s refreshing to find a contractor the lives up to 100% of his word.They know the work and quality is everything.He’s takes the time to understand what is needed and the right system to address what you need.
