The Only Duro-Last® Master Installers Serving the Denver Metro Area

At Up Top Roofing, we don’t just install Duro-Last roofing systems—we meet the highest standards set by the manufacturer. As the only Duro-Last Master Installers in the Denver Metro area, our work is certified, inspected, and backed by the industry’s strongest warranty.

While many contractors can install generic roofing systems, Duro-Last only partners with experienced, credentialed teams. Every Up Top installation is inspected on-site by Duro-Last’s own technical staff, ensuring strict quality control and long-term performance. Installers are independently rated and verified, offering unmatched accountability and peace of mind for property owners.

Proven Duro-Last Expertise

Our team has installed millions of square feet of Duro-Last roofing across Colorado, supporting commercial and industrial properties with long-lasting, energy-efficient protection. We start by precisely measuring your roof, including all penetrations like HVAC units, plumbing stacks, skylights, and access hatches. These details are sent to Duro-Last for custom fabrication, eliminating most of the onsite seaming that introduces potential points of failure.

The result:

• Faster installation with less disruption

• Fewer seams, fewer leaks

• Superior fit and finish

• Certified warranty coverage on materials and labor

Why Duro-Last Roofing?

Unmatched Prefabrication Advantage
Up to 85% of seams are completed in the factory, under climate-controlled conditions. That means better performance and less labor variability compared to systems installed entirely on-site. With Duro-Last, you’re paying for consistency—not field guesswork.

Industry’s Strongest Warranty

• Full coverage of materials and labor

• Optional consequential damage protection (covering damaged equipment or inventory caused by a roof failure)

• Warranties issued directly by Duro-Last, not just the contractor

Comprehensive Single-System Design
From insulation and membranes to flashing, skylights, scuppers, and drainage, Duro-Last provides a complete system with a single point of accountability.
