Ice Damming and Ventilation

Why is Ventilation so important when it comes to ice damming?
Your Attic needs to be able to "breath". In the winter when your homes heat can not escape your attic fast enough it heats up the surface of you roof and water melts from the top down to the cooler area at the eave were it then re freezes.When this ice builds up, it creates a dam of ice, water builds up behind the dam therefore entering your house. Remember a roof is designed to shed water not hold water.
