Good attic ventilation is important for preventing ice dams in the winter.
The intake vents work with ridge vents to allow cool air to enter the attic space forcing warm air to exit through the ridge vents.
Now that we ve reviewed how ventilation works.
See the benefits of attic ventilation a new roof is more than just shingles.
In cold climates the primary purpose of attic or roof ventilation is to maintain a cold roof temperature to control ice dams created by melting snow and to vent moisture that moves from the conditioned space to the attic ventilation acts to bypass the vapour barrier created by most roof.
While hardly anybody agrees on the best roof ventilation system everybody agrees some roof vents do hardly any good at all.

The airflow from the soffits to the ridge vent keeps the roof cool and prevents ice dams and the material will block that flow.
Located at the edges of the roof these intake vents can be installed at the eaves under the soffit at the drip edge or under the shingles at the roof s edge.
Attic ventilation in the winter.
While heat migrates in the summer because your attic is acting as a giant pressure cooker in the winter the attic space is colder allowing more room for the heat to rise and bring all that warm cozy.
It channels the exhaust gases to the vent and helps maintain proper atmospheric pressure in the waste system.
