What is a common issue that needs to be addressed for steep slope roofs undergoing freeze-thaw cycles?

Ice damming and drainage are critical issues for steep slope roofs, particularly when these roofs undergo freeze-thaw cycles. During the winter, when snow melts on a warm part of the roof and then refreezes at the eaves or overhangs, ice dams can form. This blockage prevents proper drainage of water, causing it to pool up on the roof surface. When this situation occurs, it can lead to significant water infiltration under the roofing materials, potentially resulting in leaks, water damage, and structural issues inside the building.

Proper drainage systems, such as guttering and downspouts, need to be in place to manage the melting snow and prevent water from sitting on the roof. Additionally, ensuring that the roof is designed to handle such conditions, including proper slopes and ventilation, is essential for mitigating the effects of freeze-thaw cycles. Addressing ice damming is crucial to maintaining the integrity and longevity of steep slope roofs.
