Now that we ve reviewed how ventilation works.

Good attic ventilation is important for preventing ice dams in the winter. Its drainage and vent functions are actually two systems. Effective attic ventilation systems reduce damaging heat and moisture in your attic promote energy efficiency by helping to reduce the load on your air conditioner in the summer and also reduce the risk of ice dam formation on your roof. 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.

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. The purpose of these vents is to keep air circulating in the attic which helps control ice dams in winter prevents overheating in summer and controls moisture all.
