What Is An Ice Dam & How Does It Form?

An ice dam is the accumulation of frozen water on the edge of a roofing system.  This is the result of inconsistent roofing temperatures.  Here’s how an ice dam can form on a home.

Causes Of Ice Dams

  1. Inadequate insulation & ventilation cause heat to rise, melting snow & ice on the roof.
  2. Once snow & ice melt, water begins to run down the roof.
  3. Water reaches the roofline and refreezes, causing an ice dam.
  4. Trapped water follows the path of least resistance & flows into the attic.

What Ice Dam Problems Do Homeowners Face?

Condensation can happen when heat loss from the home reaches the attic.  When this occurs, warm air meets cold surfaces causing attic frost formation. When exterior temperatures warm up, the attic frost melts. This creates an array of problems including:
