Understanding Your Attic Ventilation

For many homeowners, attic ventilation is the least of their concerns. After all, the attic is often a forgotten space inside the home. However, what many homeowners don’t know is that a well-ventilated attic is important because it helps regulate the temperature inside the house, which can ultimately contribute to a comfortable home.

Since the proper attic ventilation is what keeps your house warm in the winter and cool enough in the summer, it’s essential to understand how it all works.

What Is Attic Ventilation and Why It’s Important
Attic ventilation refers to the way an attic is designed to move air out and in. Adequate ventilation maintains a cool room temperature to control ice dams that are a result of melting snow and to reduce condensation that can build up in the attic space.

In warmer climates, attic ventilation helps expels the hot air created by the sun which can drastically help cut cooling costs. You’ll find that a lack of ventilation will cause a load of frost accumulation inside the attic during the winter which can cause excessive moisture and mold growth while during the summer months your air conditioner will be working overtime to cool off your home.

Types of Attic Ventilation
There are several methods that can be used to properly ventilate your attic space depending on the design and construction of the roof or attic. Here are some of the most common attic ventilation methods:

Roof vents should be a part of your attic ventilation system. The size and type of roof vents that can be used should be determined by a professional who has thoroughly assessed the construction of your home. Keep in mind when installing roof vents that you are better off with the excessive intake ventilation rather too little of it.

Attic Fan
Most homeowners opt to install an attic fan which works by drawing in cooler air from outside. If your attic is equipped with soffit vents that are sealed off then your home won’t likely benefit from this ventilation method.

You also have the option of adding insulation to your attic. This method adds warmth but it also allows for cool air to enter through the vents.

Benefits of Ventilating The Attic
A well-ventilated attic aids in decreasing your annual energy costs. It also improves the overall air circulation and extends the life of your roof. If your attic is lacking in ventilation, consider installing an attic fan, like the QuietCool Smart Attic Gable Fan – 2830 CFM or SmartAttic Roof Mount Fan SMT 2.0 2116 CFM to reap all the benefits it provides.
