Freeze-Thaw Cycles: How Changing Winter Temperatures Damage Your Home’s Exterior

The exterior of a home goes through a lot in the winter. As temperatures begin to fluctuate between above and below freezing, this can create a freeze-thaw cycle. Repeated cycles can cause different issues for roofing, siding, gutters, and other exterior components.

Understanding these cycles can help homeowners understand how potential problems may happen, allowing them to take steps to protect their homes throughout the winter.

What Is a Freeze-Thaw Cycle?

A freeze-thaw cycle can happen when water seeps into small cracks or gaps in exterior materials, freezing as temperatures drop and expands. When it gets warmer again, the ice melts, allowing water to penetrate deeper into these tiny openings. As this process repeats over and over, small cracks can widen, leading to more significant damage.

This can affect roof shingles, flashing, and much more over time. 

How Can Freeze-Thaw Cycles Damage Your Home?

Roofs are vulnerable when damaged shingles allow moisture to enter. As water freezes and thaws, existing issues may worsen, increasing the risk of leaks.

Siding can develop cracks or gaps as well, allowing moisture behind exterior panels. This can worsen water damage and may affect the materials beneath the siding. Gutters and downspouts are another concern since freezing water can contribute to blockages, added weight, and damage to the drainage system.

How Can You Protect Your Home?

One of the best ways to reduce the risk of winter damage is with preventative maintenance. Having roof inspections before the winter arrives is a great way to spot visible signs of wear ahead of time. Call CR3 American Exteriors today for a free inspection.
