OVERVIEW

Year round ventilating of your attic minimizes harmful moisture in the winter and lowers the temperature of your home in the summer. Keeping your attic cool and dry can extend the life of your roof, by preventing rot, premature aging,
and damaging shingle distortion that can result from excessive heat. A cool attic in summer also saves you money on your energy bill and extends the life of your air conditioner.

HOW MUCH ATTIC VENTILATION DO YOU NEED?

Effective ventilation requires air to exit at or near the peak of the roof with replacement air drawn through soffit venting and louvers. The Home Ventilating Institute (HVI) recommends at least 10 air changes hourly to equalize
temperature.
