Interstate was founded 1994 in Denver, CO as a small to mid-sized local company with a focus on residential service. Through continuous upward growth we are now among the largest contractors in the United States with projected annual sales reaching almost 50 Million in 2012.Through research & technology Interstate develops solutions to some of the most complex applications that exist. We've answered the call for more efficient, sustainable and enjoyable solutions, and continue to be a leader in product innovation such as solar integration. But most all, our employees are what make us a national leader in roofing.
