The Impact of Freeze-Thaw Cycles on Your Roof

In the Chicagoland area, we’re no strangers to unpredictable weather. One day can feel like spring, and the next, we’re back in a deep freeze. This constant back-and-forth, known as the freeze-thaw cycle, takes a serious toll on your home’s exterior, especially the roof. We at Berg Home Improvements have seen firsthand the damage this can cause. Understanding how these cycles affect your roof is the first step in protecting your most important asset.

Here’s what you need to know:

• How freeze-thaw cycles damage your roof.
• The hidden dangers of ice dams.
• Key maintenance tips to prevent costly repairs.
• Proven strategies to protect your home.

What Is a Freeze-Thaw Cycle and Why Is It a Problem?

You may be asking, “What is a freeze-thaw cycle?” It’s a simple process with powerful consequences. During the day, snow and ice on your roof melt as temperatures rise or the sun comes out. This water seeps into tiny cracks and crevices in your shingles and other roofing materials. When temperatures drop below freezing overnight, that water expands as it turns to ice, widening the cracks. This process repeats itself, creating larger gaps and compromising the integrity of your roof.

This constant expansion and contraction often results in cracked, curled, or dislodged shingles, exposing your home to potential leaks and water damage. Over time, what started as a microscopic fissure can become a major entry point for water, leading to rotted wood, damaged insulation, and mold growth in your attic.

The Hidden Danger of Ice Dams

One of the most destructive results of the freeze-thaw cycle is the formation of ice dams. An ice dam is a ridge of ice that forms at the edge of a roof, preventing melting snow from draining properly. As water backs up behind the dam, it is forced underneath your shingles and into your home. This is where we see some of the most significant water damage.

How Can I Protect My Roof From Freeze-Thaw Damage?

It’s always more cost-effective to prevent damage than to fix it later. Regular inspections are your best defense. Check your roof for signs of wear, such as missing or damaged shingles, especially after a harsh winter. Proper attic ventilation is crucial. It helps regulate your roof’s temperature, thereby reducing the harmful melting and refreezing that cause ice dams.

For a more permanent solution, consider upgrading your roofing materials. We install durable, algae-resistant shingles, expertly designed to withstand Illinois’ extreme weather. These materials offer superior protection and durability, ensuring your roof remains strong season after season.
