Some relationships just work. And after 15 years, our partnership with Duro-Last Roofing is one we’re genuinely proud of.

This month, we received an updated authorization letter from Duro-Last confirming what we’ve worked hard to earn and maintain: Platinum Contractor status. It’s not a designation handed out freely. It reflects consistent, high-quality installation work, ongoing training, and a commitment to doing things the right way, every single time.

For those who aren’t familiar, Duro-Last is the nation’s largest manufacturer of custom prefabricated roofing systems, with over 2 billion square feet of roofing installed across the country. They set a high bar, and they expect their contractors to meet it. We’ve been part of their authorized dealer and contractor network since 2011, and earning Platinum status means we’ve not only met that bar, we’ve stayed there.

What does that mean for you as a school district, university, or facility manager? It means when Coryell shows up to assess, design, or install your roof, you’re working with a team that has been formally trained, independently evaluated, and recognized for quality by one of the most trusted names in commercial roofing. That’s not something we just say about ourselves. It’s documented.

We work across Arkansas, Kansas, Missouri, Oklahoma, Tennessee, and Texas, and in every market, the question we hear most from facilities and procurement teams is some version of:

“How do we know we can trust you?”

This letter is part of that answer. Our track record is another part. The relationships we’ve built with the schools, colleges, and institutions we serve over the years are the rest of it.

Trust in this industry is earned slowly and lost quickly. We don’t take that lightly. Being a Platinum Duro-Last contractor is one more way we can show up to a conversation and say, with confidence, that the work we do is backed by more than just our word.

We’ve been a Duro-Last Platinum Contractor since 2011, and we have the paperwork to prove it. Don’t just take our word for it… read the letter.

If you’d like to learn more about what a Duro-Last roofing system could mean for your facility or just want to talk through what you’re working with, we’d love to connect.
