Proudly Serving Denver since 1967
For more than 55 years, Arapahoe Roofing has been a family of craftspeople, problem-solvers, and straight-shooters. Our team includes roofers who’ve been with us for decades, sheet metal specialists trained in our own shop, and project leads who’ve worked on everything from historic churches to Denver Union Station. We’re proud of the work — but we’re even prouder of the people who do it.
Bob Bellitt is the Founder of Arapahoe Roofing. He started the company with a dream to provide quality roofs at an honest price in 1967. Bob has been a key figure in the roofing industry in Colorado and helped in the creation of the CRA “Colorado Roofing Association” to safeguard customers from “Storm Chaser” companies and to hold the industry, to the highest standards of operations. Bob has seen a lot of changes in the industry throughout the years but has always made the changes necessary to keep up with the trends, while keeping his strong core of roofing knowledge and “what just works” and doesn’t need changing. This is evident by his continued success and longevity in the industry as well as the family atmosphere that he has created, which is apparent by the many long-term employees that Arapahoe Roofing can boast about. Bob is “semi-retired” but still manages to “check in” at the office on an almost everyday basis.
