Our local Bemidji, Grand Rapids, and Hibbing teams respond to water damage emergencies throughout the year in Bemidji. Water leaks are clear and often the most obvious sign of ice dam damage, and they can lead to significant water intrusion inside your home. Here's how ice dams cause water leaks:
Ice Dam Formation: Ice dams develop when snow on your roof's upper, warmer section melts due to heat escaping from your home's interior. This melted snow flows downward toward the eaves, which are colder because they extend beyond the heated living space.
Blocked Drainage: As the melted water reaches the eaves, it encounters freezing temperatures and refreezes, forming an ice dam along the roof's edge. This ice barrier prevents further drainage of water off the roof.
Water Backup: With nowhere to go, the trapped water can pool behind the ice dam and begin to back up under your roofing shingles. It can also seep through any cracks or gaps in the roof's structure.
Interior Water Damage: As water infiltrates beneath the roofing materials, it can penetrate the roof deck, and underlayment, and eventually reach the attic space. Once inside, it can drip onto your insulation, ceiling, or drywall.
Secondary Damage: Prolonged exposure to moisture can lead to mold and mildew growth in your attic and insulation.
