Why Choose United Roofing of Colorado?

Installed With No Disruptions

United Roofing of Colorado is an authorized Duro-Last contractor – we use no loud machinery, hot tar, or make messes. Duro-Last Roofing Systems are serviceable and can easily be repaired without heavy equipment or an entire replacement. That means no downtime!

Durability = True Performance

The unique formulation of Duro-Last Roofing Systems delivers long-term value and peace of mind. Two differentiators Duro-Last offers are a high-quality reinforcement scrim and thickness above scrim.

Knitted in-house, our anti-wicking polyester weft-insertion scrim has a 14 x 18 or 14 x 9 threads-per-inch density – among the highest in the industry. Duro-Last’s scrim uses a third tie yarn to prevent runs and doesn’t allow tears to spread. The scrim is the backbone of all Duro-Last’s membranes, giving them their strength and puncture resistance.

Duro-Last’s thickness over scrim – also known as the “performance layer” – is thick, making our membranes extra durable. This means that Duro-Last Roofing Systems provide protection where your building needs it most: the exposed surface of the membrane.

Energy Efficient

By reflecting up to 88% of the sun’s energy, Duro-Last white roofing systems can significantly reduce energy costs. To learn more, visit the Duro-Last website at

Industry Leading Warranties

Duro-Last warranties provide unparalleled protection for roofing applications. We were the first manufacturer to offer a warranty covering consequential damages. United Roofing of Colorado also provides a 1-year transferrable warranty on all workmanship.

The Prefabrication Advantage

Through Duro-Last’s prefabricated roofing systems, including both membrane and accessories, up to 85% of the seams can be completed in their factory-controlled environment. This eliminates most of the on-site fabrication that can lead to roof leaks.
