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. Intake vents located at the lowest part of the roof under the eaves allow cool. In the summer good attic ventilation reduces heat buildup. You would think that venting an attic would be counterintuitive in the winter or cold months.

Roof vents remove warm air during the winter. Most experts contend that a well ventilated attic keeps the house more comfortable in summer and guards against moist heated air building up in winter.
