Denver, Colorado's WEATHER CAN BE HARSH FOR COMMERCIAL ROOFING

Denver, Colorado experiences a semi-arid climate with four distinct seasons and wide variations in temperature throughout the year. Summers are typically warm and dry, with average high temperatures in the 80s and occasional heatwaves reaching the 90s. The intense sunlight and low humidity can cause roofing materials to dry out and become brittle over time, particularly on flat or low-slope commercial roofs. UV exposure at Denver’s high elevation—over 5,000 feet above sea level—is also more intense than in many other U.S. cities, accelerating the aging and degradation of roof membranes and coatings.


Winters in Denver bring cold temperatures, snowfall, and frequent freeze-thaw cycles. Snow accumulation and ice buildup on commercial roofs can add significant weight and cause drainage systems to clog or freeze, leading to water backup and potential leaks. As snow melts during the day and refreezes overnight, it can infiltrate small cracks in the roofing system and expand when frozen, causing further damage. Ice dams and snowdrifts on low-slope roofs are additional concerns that require proper insulation, drainage, and maintenance to mitigate.


Spring and fall in Denver are marked by rapidly changing weather, including strong winds, hailstorms, and sudden temperature shifts. Hail is a particular threat in this region, capable of puncturing roofing membranes, denting metal components, and damaging rooftop equipment. These seasonal extremes place consistent stress on commercial roofing systems, making routine inspections and proactive maintenance essential. Nations Roof offers commercial property owners in the Denver area customized roofing solutions that account for the city’s elevation, dry climate, and weather volatility—ensuring durability and long-term performance throughout the year.
