Douglass Colony Group Inc.

Roofing, Metals and Energy-efficient Options

Douglass Colony Group Inc. (DCG) is a Colorado-based full-service specialty contractor with locations in Greeley, Colorado Springs and Glenwood Springs, and headquarters in Commerce City. DCG employs over 350 people between its four locations and continues to add positions frequently to deal with the growing demand. Since 1947 DCG has grown to become the largest commercial roofing contractor in Colorado with the biggest service/maintenance division.

The company embodies regional presence for all product lines, including roofing, metals, solar, waterproofing, day lighting, service work and more. “DCG is licensed in many states,” says Christy Maraone, director of marketing for DCG. “Last year we performed work in 15 different states. We anticipate work in additional states this year, and even more in the years to come.”

The company’s history dates back to 1947 when Douglass Roofing started as a single office in Greeley. Douglass Roofing worked alongside Colony Metals since 1982 and eventually merged with the architectural metal systems company in 2009. Douglass Roofing assumed the name Douglass Colony Group, and the team’s capabilities expanded even further.

DCG performs work on many LEED-certified projects with energy-efficient products such as solar, garden roofing, daylighting, sunscreens and reflective/white roofing. The company’s ability has won DCG numerous awards, including the 2011 Silver Associated General Contractors’ Award for Construction Excellence for the team’s performance at St. Anthony’s Hospital in Lakewood, Colo.

“This landmark project marks the largest roof DCG has installed to date,” says Maraone. The project involved the installed of an 180,000-square foot tan TPO membrane, custom flashing sheet metal, composite panels and soffits.

The company was also awarded a 2010 Silver Associated General Contractors’ Award for Construction Excellence for work performed at the LEED Gold-certified St. Mary’s Hospital in Grand Junction, Colo. The project scope included 100,000 square feet of EPDM and PVC roofing, plaza paver decks with hot fluid-applied waterproofing, over 100,000 square feet – consisting of 8,800 panels – of custom-made rainscreen metal wall panels as well as composite metal wall panels for columns and beams.

DCG performs work on a large variety of LEED-certified projects, including the Lindsey-Flanigan Courthouse in Denver, Colo. DCG installed a 68,000-square foot white TPO tapered roof system, a 215 mil hot fluid-applied waterproofing system over 8,000 square feet of the roof, two cutting-edge garden roof systems with pedestal-mounted plaza pavers and a unique composite wall panel system with custom sunshades.

“DCG’s energy-efficient additions enabled this prestigious city landmark to achieve a LEED Silver certification,” says Maraone. “All metal products were designed and fabricated at our Commerce City headquarter location in our 70,000-square foot fabrication facility for the highest level of customization and efficiency. This allows for full-customization, reduced overhead costs and reduced lead time getting the products to the jobsite.” The facility uses energy-efficient motion-censored lighting to reduce electrical expenses.

DCG was also a key contractor in the construction of RSF I and RSF II at the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) in Golden, Colo. NREL is the nation’s primary research and development laboratory for renewable energy and energy efficiency, as well as the largest net-zero building in the U.S. Both RSF I and RSF II have achieved LEED Platinum certification, as well as unbelievable energy savings, at 50 percent less than a standard office building.

“On RSF II DCG designed, fabricated and installed 8,000 Rheinzink panels, which is a completely natural material at 99-percent recycled,” says Maraone. “It maintains an average lifespan of 200 years in the Colorado climate. DCG also installed the flashings and unit for a passive solar wall. These solar walls act as a solar air heating system by preheating the freshly ventilated air using the sun and as a result reduce heating costs and green house gas emissions.”

LEED by Example

As a committed industry leader, DCG offers a variety of energy-saving, green technologies, including solar, sunscreens, day lighting, reflective roofing and garden roofing. In addition, all of DCG’s sales representatives are LEED Accredited Professionals (LEED APs), and the company’s solar representatives are also NABCEP-certified.

Even DCG’s headquarters, which is LEED Silver certified, is a representation of DCG’s commitment to go green. The company’s headquarters utilizes a variety of energy-saving products, including three different solar technologies, sunscreens, reflective/white roofing and daylighting.

“Our rooftop solar array is one of the largest in Commerce City,” says Maraone. “It is unique in the fact that all three technologies are individually monitored for accurate reporting of each product to customers.” The system promises an ROI of four to five years.

“DCG has been around for 65 years and there are many things that contribute to its past and present success: teamwork, product line diversification, national coverage, excellent customer service, experience, quality work, high safety standards, and our focus on green or sustainable technologies,” says Maraone. “DCG upholds the highest standards in customer service, safety and quality on every job and this keeps repeat customers and attracts new ones.” The numbers reflect DCG’s focused corporate culture with revenues up 15 percent from 2010 to 2011.

The secret to DCG’s success boils down to the company’s employees. “As a diversified company, when we bid a job, we bid all company competencies,” says Maraone. “This includes roofing, metal, solar, waterproofing and more. Between all offices and all divisions, we communicate and work as a team for all bid proposals locally and nationally.”

Safety First

DCG is committed to a safe work environment. According to Maraone, all DCG foremen, superintendents and project managers are 30-hour OSHA certified. “DCG is often selected for projects based on their high safety standards,” says Maraone. “DCG is one of the safest in the industry, employing a zero-accident culture of safety through regular, comprehensive training for all field employees.”

DCG was able to offset much of the market fluctuations these past few years by offering diversified products and services and expanding services nationwide. “We’ve certainly experienced our ups and downs within different market segments, but our diversified portfolio minimizes those market impacts and allows us to keep growing,” Maraone says. “Focusing on sustainable products has been a key focus of DCG.”

The company’s product offerings and contributions on key LEED-certified projects has established Douglass Colony Group Inc. as a sustainable technology leader that advocates for a brighter tomorrow.
