Waukesha, Wisconsin's WEATHER CAN BE HARSH FOR COMMERCIAL ROOFING

Milwaukee, Wisconsin experiences a humid continental climate with cold, snowy winters and warm, humid summers—creating a wide range of weather conditions that can significantly impact commercial roofing systems. Summers typically bring temperatures in the 70s and 80s, along with periodic thunderstorms and high humidity. These storms can produce heavy rain, strong winds, and hail, all of which can damage roofing membranes, dislodge flashing, and overwhelm drainage systems if not properly maintained. Prolonged sun exposure can also lead to the gradual breakdown of roofing materials, especially on older or unprotected systems.


Winters in Milwaukee are long and harsh, with average temperatures often dipping well below freezing and significant snowfall throughout the season. The frequent freeze-thaw cycles pose a major challenge to commercial roofs, as water can seep into small cracks and expand when frozen, worsening the damage over time. Snow accumulation and ice buildup can place excessive weight on the structure and cause ice dams, which can lead to water infiltration beneath the roofing membrane—especially on flat or low-slope roofs.


Spring and fall bring rapid temperature changes, gusty winds, and additional rainfall, which further stress roofing systems through constant expansion and contraction of materials. These conditions highlight the importance of preventive maintenance and routine inspections. Nations Roof provides tailored commercial roofing solutions in the Milwaukee area, offering services designed to identify weather-related vulnerabilities early and extend the lifespan of roofing systems. With a proactive approach, property owners can protect their investments and ensure year-round building performance despite Milwaukee’s demanding climate.
