Roofs worthy of what's underneath them.
Architectural, Class 4, metal and tile roofing for the Front Range's finest homes and buildings, from a family company founded in 1968 and based in Centennial.
Craft, across every kind of roof.
Nine services for homes and commercial buildings. Each begins with a free inspection and a written proposal, and ends with a registered manufacturer warranty and our own craftsmanship guarantee, seven years on every replacement.
Recent work, before and after.

The details a fine home requires.
Larger roofs, steeper pitches, complex valleys, designer materials and architectural review. We have done this work on the Front Range's custom homes for three generations, and we run it the way you would expect.

Cameron Hummell is the CEO of GEN 3 Roofing Corp., a third-generation family roofing company serving the Denver Metro and Colorado Springs since 1968.
Before roofing he ran a $400 million home-building site as superintendent, and he runs GEN 3 the same way: a written scope before work starts, one project manager you can reach, and a company built to be at the same office, with the same phone number, when your warranty is twenty years old.
