Attic Ventilation Summer

In the summer natural air flow in a well vented attic moves super heated air out of the attic protecting roof shingles and removing moisture.

Attic ventilation summer. Insufficient ventilation can lead to moisture problems during the winter and decreased energy efficiency during the summer but too much ventilation can be just as bad if not worse. This prevents hot air from seeping into your home and driving up the temperature in the living space which reduces the load on your air conditioner. And since hot air rises and is exactly what you want to vent out of your attic exhaust vents should always be installed at or near the top of the roof. That cuts cooling costs and prolongs shingle life.

In the summer good attic ventilation reduces heat buildup. Attic ventilation fans help cool air your attic by pushing out the stifling hot air from inside the attic and bringing in cool air from outside. Also moisture produced within the home may move into the attic if ceiling vapor barriers are not used. Learn how to install them in this article.

Attic ventilation works on the principle that heated air naturally rises primarily utilizing two types of vents. By the diy experts of the family handyman magazine.

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. Roof and soffit vents reduce cooling costs in summer prevents ice dams in the winter extend the life of your shingles and prevent mildew and rot by reducing moisture buildup. Intake vents located at the lowest part of the roof under the eaves allow cool.

The goal of roof ventilation is to get fresh relatively cool air into the attic and vent out hot moist air. The insulation will resist heat transfer into the house.
