Built to Brew, Engineered to Last
Inside the G150 Molson Coors Roofing Project
by Aaron Harvey, Construction Executive, Douglass Colony Group
Located in the heart of Golden, Colorado, the new Molson Coors Brewery, nicknamed “G150” to commemorate 150 years of brewing at the site, is a forward-looking, high-performance facility built from the ground up. This brewery includes production areas, fermentation halls, cold storage, and administrative offices, all designed and built for energy efficiency, operational scalability, and durability.
Adolph Coors came to America to fulfill his dream to operate a brewery that produced good, quality beer. To accomplish this goal, he made his way to the West and found a clean, pure water source in Clear Creek in Golden. To this day the freshly modernized Golden Brewery still uses water from Clear Creek and helps many organizations with water conservation efforts throughout the American West.
Installed by a licensed Elevate applicator, Douglass Colony Group, the brewery’s roofing system was designed for long-term durability and performance. This project earned Douglass Colony the 2025 Elevate Excellence Award in the “Durability” category, recognizing “exceptional, robust roofing systems that stand up to the toughest conditions.” Their expert installation delivered a resilient, high-performing system that meets the demands of an ambitious design and challenging project environment.
At nearly 150,000 square feet and spanning 18 distinct roof areas, this project demanded precise sequencing and expert coordination. Each zone varied in elevation and purpose, with unique requirements for different parts of the facility: offices, production areas, and cold storage. The design was further complicated by the presence of over 100 fermentation tanks, each attached to a roof-mounted concrete curb approximately 35 feet in diameter. To seal these curved penetrations, Douglass Colony Group used Elevate UltraPly™ TPO XR fleece-backed membrane, creating a watertight bond with the roof where typical flashing methods wouldn’t suffice.
Roofing work began in the middle of winter against sub-freezing temperatures and adhesive limitations. As a result, the team relied on heated storage solutions and nightly tie-ins. Access was another hurdle. Many roof sections couldn’t accommodate standard adhesive carts, so the Douglass Colony crew adapted by retrofitting equipment with 150-foot heated hoses, allowing them to reach all areas and keep the project on schedule.
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 two-inch base layer, a tapered layer, and custom-sloped variations to promote drainage. A half-inch DensDeck® Prime coverboard was then applied on top, securely bonded with I.S.O. Spray™ R.
With weather a factor throughout the installation, the Douglass Colony Group team followed strict protocols for staging, temperature management, and sequencing. The result is a seamless, high-performance roofing system that reflects both the technical demands of the brewery and the craftsmanship of the team that installed it.
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.
Golden Brewery employees are generous within the community donating $110,000 and racking up an average of 7,000 volunteer hours per year. Now outfitted with a whole new look and a durable, weather resistant roof, the Golden Brewery can continue to produce quality beer and serve their community.
