Commercial Roofing

Built to Perform. Engineered to Last.

Celebrating 100+ Years!

United Materials has built quality commercial roofs for over a century.

Founded in 1923, we quickly earned our sterling reputation as the premier commercial roofing company in Colorado, serving the private sector and fulfilling government contracts.

Talk to a Commercial Roofing Expert

United Materials Endorsements

We are passionate about Colorado communities and the incredible businesses and people within them.

We let our customers do the talking... Hear what they have to say about our expert craftsmanship!

Unted Materials has been our valued roofing partner since the early 1980s. From our first small repair,  we have relied on United for their roofing experience and expertise, and are big fans of their RoofGuard program, where for a small monthly fee we don’t have to worry about roofing repair costs. United, under this program, is very proactive and monitors the condition of the roof and makes repairs, if needed, at no cost - - - it’s all covered.
