"I feel that Ridge Vents-when coupled with Soffit Vents are one of the Greatest Energy Efficient Building Materials on the Market today to prevent Ice Dams". Scotty-Scotts Contracting, St Louis Renewable Energy
In a cold climate, the primary purpose of ventilation is to maintain a cold roof temperature to avoid ice dams created by melting snow and to vent any moisture that moves from the conditioned living space to the attic.
"So much information has been devoted to the subject of roof venting that it's easy to become confused and to lose focus. So I'll start by saying something that might sound controversial, but really isn't: A vented attic, where insulation is placed on an air-sealed attic floor, is one of the most underappreciated building assemblies that we have in the history of building science. It's hard to screw up this approach. A vented attic works in hot climates, mixed climates, and cold climates. It works in the Arctic and in the Amazon. It works absolutely everywhere—when executed properly.[ http://stlouisrenewableenergy.blogspot.com/2011/08/roof-venting-and-its-importance-for.html ]"
