Our Founders

We’ve been in construction since we were teenagers.

 

We loved the construction industry, but we didn’t necessarily love the companies. We saw an opportunity to build a construction company where we would like to work, a company that puts people first. So, we did.

 

Turns out, putting people first is good for business. Our staff and company culture are exceptional, customers love our industry-leading products, and our customer service is unrivaled.

 

“From shingles, to sealants, we only use the products that have a track record of success in the Colorado climate. If it’s not Built for Colorado, then we don’t use it.”
