If you’re looking for a proven flat roofing system that can handle Colorado’s unpredictable weather and last for decades, a modified bitumen roof in Denver may be exactly what your property needs.

In our experience, modified bitumen roofs last 25–30 years with regular maintenance. The layered structure stands up well to hail, sun, and freeze cycles that are common in Colorado. Many clients also apply reflective coatings every 10 years to extend lifespan and reduce energy costs.
APP (atactic polypropylene) membranes are heat-welded and perform best in sunny, hot environments. SBS (styrene-butadiene-styrene) membranes are more flexible and better for cold climates like Denver. Our team will recommend the best type for your roof based on structure and environment.
It depends on your roof type and usage. Modified bitumen offers stronger resistance to punctures and wear from rooftop foot traffic. It also handles temperature fluctuations exceptionally well. TPO is more reflective, while EPDM is flexible and affordable. We’ll guide you through the best choice for your structure.
In many cases, yes. As long as the existing roof is structurally sound and meets local codes, we can install a modified bitumen overlay. We’ll evaluate your roof deck, drainage system, and insulation before proceeding.
Not much, but the little it does need makes a big difference. We recommend bi-annual 35-Point Comprehensive Property Inspection, debris clearing from drains, and resealing any vulnerable seams or flashings. With that care, your system will perform at peak condition for decades.
We don’t just work here. We live here. From mountain towns to metro neighborhoods, we serve homeowners and businesses across Colorado’s Front Range with the same attention and accountability we’d want for our homes. If you’re in or near one of the communities below, you’re in our service area.
