Freeze-Thaw Cycle Roof Damage: The Hidden Cause of Roof Damage for Eureka Homeowners

Winters in Missouri, as St. Louis County homeowners well know, bring more than just dropping temperatures—they also bring the risk of repeated freeze-thaw cycles that can cause invisible damage that becomes a costly fix. Throughout the winter season, water will seep beneath and between shingles, underlayment, and roof decking, and when that moisture goes through several cycles of freezing and thawing it will result in cracks, leaks, and long term structural damage that homeowners will have to deal with.

How Freeze-Thaw Cycles Damage Roofs In Missouri

Due to frequent fluctuations in temperature both above and below freezing—sometimes within the same day—moisture on and in your roof can cause hidden damage you don’t see until it’s too late. These consistent freeze-thaw cycles are a cause of various common roofing problems homeowners face in St. Louis County. 

The damage begins when the moisture from winter rain, ice, slush, and snow, seep into the minute cracks in your roof. Then, when the temperature drops and that moisture freezes, the ice pushes your shingles apart. And when temperatures rise again, the ice will melt, and the space created by the ice will provide a larger gap for more moisture to pool. Commonly, this process will repeat throughout the season, leading to:

• Cracked or broken shingles

• Loose flashing

• Deteriorated underlayment, which allows moisture to reach the decking of your roof

• Subtle leaks that eventually develop into major problems

Winter weather in Missouri can rapidly shift, meaning homeowners throughout St. Louis County struggle with protecting their roofs from freeze-thaw cycles that work silently to destroy their roofs beneath the surface. As the roofing partner for Eureka homeowners, we focus on identifying and addressing the early warning signs before they have a chance to escalate into costly damage later on.
