The Hidden Risk of Freeze-Thaw Season

The Hidden Risk of Freeze-Thaw Season

| February 17, 2026

February in Chicagoland is deceptive.

One week it’s below zero. The next, it’s 50 degrees and melting. That freeze-thaw cycle is one of the most damaging weather patterns in our area.

And it’s happening right now.

What Freeze-Thaw Actually Does

When snow melts during the day and refreezes at night:

  • Ice dams form along rooflines

  • Gutters expand and crack

  • Water backs up under shingles

  • Brick and masonry begin to deteriorate

  • Foundation cracks expand

For luxury homes with slate roofs, cedar shake, or intricate gutter systems, the damage can be especially costly.

What Many Homeowners Don’t Realize

Most policies cover sudden and accidental water damage — butnot long-term seepagedue to poor maintenance.

If ice dams cause interior water damage, coverage may depend on:

  • Roof age

  • Maintenance history

  • Policy endorsements

Action Steps for February

  1. Inspect attic insulation and ventilation

  2. Clear heavy snow accumulation safely

  3. Review your water backup coverage

  4. Confirm replacement cost adequacy

This is one of the most common late-winter claim scenarios we see in the North Shore.
