Commercial and public work

Roofs we've delivered across Colorado

Recent public projects include the Greeley Transit Center, Southridge Golf Course, Twin Silos Park, CSU Pueblo, Yampa River State Park, Mariana Butte Golf Course and the Pueblo Zoo.

Flat roofs on the Front Range take strong sun, hail and snow. We'll recommend the system that fits your building, your budget and how long you plan to own it.

Questions

Commercial roofing FAQs

TPO or EPDM: which is better?

Both are proven. TPO is a white, heat welded membrane that reflects the sun. EPDM is a black rubber membrane that's been used on commercial roofs for decades. We'll recommend one based on your building, budget and plans.

Can my roof be coated instead of replaced?

Sometimes. A coating works when the existing membrane and insulation are mostly dry and sound. We check with a moisture scan before we recommend one.

Do you bid public projects?

Yes. 3G bids public work and is bonded. Send us the bid documents or invite us to the pre-bid walk.

What's an NDL warranty?

A No Dollar Limit warranty from the manufacturer covers materials and labor for covered leaks for the warranty term, with no cap on the repair cost. It requires a manufacturer inspection when the job is done.

Do you work outside Colorado Springs?

Yes. We work across Colorado, with recent projects in Greeley, Fort Collins and Pueblo.
