The Beginning

Twenty-seven years ago, we looked at the commercial roofing market and saw a gap. Business owners faced a choice: spend tens of thousands on full roof replacement or watch their roofs degrade. There was no middle ground. No practical solution that protected their investment without the massive bill.

We saw an opportunity to change that. We started GM Systems Inc because we believed quality roof protection should be accessible. Coating systems, leak repairs, waterproofing—these could extend roof life dramatically and cost far less than replacement. That frustration became our mission. It still is.

We're veteran owned. We understand accountability. We understand keeping your word. That foundation shaped how we build this company and how we treat every client across our four-state coverage area. From Joplin, MO, we've learned that reputation is everything when you serve a business community that talks to each other.

What We've Learned

Over 27 years, a few principles have become non-negotiable. The warranty matters because business owners need peace of mind. A 20-year materials and labor warranty isn't a selling point—it's proof we believe in our work. We've seen what happens when you cut corners. We chose not to.

Customer service isn't what you say in marketing. It's how you answer the phone. It's what happens when someone has a question or a problem. We've built our reputation on being accessible and honest. That consistency across commercial roof coatings, flat roof repairs, metal roof sealing, and waterproofing systems is what keeps clients coming back and referring us to others.

We've also learned that quality products matter. Silicone coatings, reflective roof systems, lasting repairs—these aren't interchangeable. We chose materials and methods that work because your roof is business-critical infrastructure. You can't afford downtime, leaks, or surprises.
