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. Ventilation of the home attic is important for two reasons. 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. 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.

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. Good ventilation allows the heat and moisture to escape. That cuts cooling costs and prolongs shingle life. 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.

Learn how to install them in this article. The most common mistake homeowners make when installing insulation is to block the flow of air at the eaves. 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. Attic ventilation works on the principle that heated air naturally rises primarily utilizing two types of vents.

The goal of roof ventilation is to get fresh relatively cool air into the attic and vent out hot moist air. During the summer excess heat that builds up in the attic during the day results in high energy costs for cooling. In the winter warm moist air seeps into the attic from the living space below. Just like properly sizing your furnace and air conditioning unit you want precisely the right amount of attic ventilation for your home.
