We don’t usually (ever?) highlight innovations among the Big Beer companies. But thought this case study on the roofing system that supports the fermentation tanks atop the Molson Coors Brewery in Golden, Colo., was worth sharing.
This Molson Coors location includes production areas, fermentation halls, cold storage, and administrative offices, all designed and built for energy efficiency, operational scalability, and durability. The nearly 150,000 square foot roof job was complicated by the presence of over 100 fermentation tanks, each attached to a roof-mounted concrete curb approximately 35 feet in diameter.
To support that load, Douglass Colony Group installed the Elevate UltraPly TPO XR fleece-backed membrane, creating a watertight bond with the roof where typical flashing methods wouldn’t suffice. Douglass Colony Group is a full-service specialty contractor that has been servicing Denver and the entire Rocky Mountain region since 1947. They are a licensed Elevate applicator.
“This project had everything—scale, complexity, winter conditions, and curved tanks everywhere you looked. It took some improvising, and definitely the right people,” said Aaron Harvey, Construction Executive at Douglass Colony Group. “I’m just proud to see it finished and performing the way we knew it could. The performance of Elevate products made it that much easier to deliver.”
This project also earned Douglass Colony the 2025 Elevate Excellence Award in the “Durability” category, recognizing “exceptional, robust roofing systems that stand up to the toughest conditions.”
Roofing System Solution
Midway through the planning phase, an Elevate UltraPly TPO system was selected for its balance of long-term durability and cost-effectiveness. The crew installed an 80-mil XR Platinum fleece-backed membrane adhered with an Elevate bonding adhesive. This combination delivers reliable protection from wind and precipitation with clean, single-weld seams measuring 1.5 inches wide.
The insulation includes a fully tapered ISOGARD system, starting with a 2-inch base layer, a tapered layer, and custom-sloped variations to promote drainage. A 0.5-inch DensDeck Prime coverboard is then applied on top, securely bonded with I.S.O. Spray R.
Performance Highlights
The roofing system installed at Molson Coors G150 is backed by a 20-year Elevate Red Shield Warranty with 120 mph wind speed coverage, providing long-term confidence for a facility designed to run 24/7. Its white, reflective UltraPly TPO membrane contributes to the brewery’s sustainability goals, supporting energy efficiency while standing up to Colorado’s strong UV exposure.
