Our Story
Douglass Colony was founded in 1947 in Greeley, Colorado and incorporated as Earl F. Douglass Roofing Co. in 1961. The Company grew and opened a Denver office in 1973. Colony Metal was formed in 1983 to fill Colorado’s need for a full-service architectural metal systems company. As our work continued to lead us south, the Colorado Springs office was opened in 1991. In 2009, Earl F. Douglass Roofing and Colony Metal were merged to provide innovative solutions and unparalleled seamless service as Douglass Colony Group, Inc. Since then, we have distinguished ourselves with an expansive line of services, high performance product lines, a professional labor force, and lasting customer relationships.
For over 70 years, Douglass Colony has been an industry leader in commercial roofing, offering innovative, effective solutions for all roofing types. As Douglass Colony’s competencies grew over the years, so did our product offerings and services. Douglass Colony’s diversified portfolio now includes roofing (flat, steep, re-roofing), metals (sunscreens, composite wall panels, light-gauge steel trusses, metal roofing, sheet metal, flashings & trim, panelized metal stud framing using the FRAMECAD system), solar (photovoltaic, rooftops, ground mounts, parking canopies, awnings), waterproofing (horizontal and vertical applications, gardens), daylighting, and commercial roofing service and maintenance.
Testimonials
I appreciate the push to get [the work at YVMC] done quickly and efficiently, and the canopy work looks great. I appreciate your help in that successful schedule. Thanks for the hard work to get this phase successfully completed.
This very complicated project included blindside waterproofing for a shotcrete basement wall, a Hydrotech roof system, 3 separate EPDM roofs that tied into existing structures, and replacement of existing clay tile roofing. It was reassuring to know we had a trade partner looking out for the contractors’, owners’, and architects’ best interests. I look forward to working with Douglas Colony on future waterproofing and roofing projects.
Great company, thanks to (my Supervisor) for giving me the opportunity to be part of this community, I’m very grateful. He is not just a boss, he is a leader.
I love the job, the people make me feel welcome. For the first time in a long time I look forward to working. My future is bright. Only up from here.
