Arkansas winters can be unpredictable. One day it’s warm and sunny, and the next it’s snowing or sleeting. Freezing temperatures can cause ice dams that trigger havoc to your home’s roof and interior if you’re not paying attention. Ice dams usually occur after a heavy snowfall or sleet and several days of freezing temperatures.
An ice dam might form when…
- There is snow or sleet on the roof
- Average outside temperature is below 32 degrees
- Roof surface temperature is above 32 degrees at its higher end and below 32 degrees at its lower end.
How an ice dam forms…
- Indoor heating rises through the ceiling into the attic and warms the roof surface
- Snow or sleet on the heated part of the roof melts and flows down until it reaches that part of the roof that is below 32 degrees – water freezes into an ice dam
- The dam grows as it is fed by melting snow or sleet above, but water held by the dam backs up and stays liquid
- Eventually, the water finds cracks in the roof covering and flows into the attic and could seep through the ceiling and interior walls.
