Vent Session – Where Does Your Hot Air Go?
There are a few main types of vents you may see on your roof: static vents, turbine vents, ridge vents, power vents, and baffled vents. Some homes have different vents based on the age, style, or need of the roof. We’ll describe each vent so you know how they’re working for your home!
Static vents are placed near the peak of the roof. Static in this case means it’s unmoving. The hot air rises from the attic and out the static vent outlet. These need intake vents that are lower, like soffit vents, to bring cooler air into the attic.
Turbine vents are designed to spin around with wind outside the home. As they spin, they draw the hot air out of the attic. Some people call these “whirlybird” vents. These are placed near the peak of the roof as well.
Ridge vents are installed along the ridge of the roof, or the very peak. This type also uses the hot air rising and soffit vent intake as the static vents, however, it is a more low-profile vent system for the roof. But, some home styles aren’t conducive to having a ridge vent installed.
Power vents are wired to the electric in the home. A thermostat is connected to it that measures the temperature in the attic and the vent turns on to draw the hot air out when it reaches a certain temperature. It turns off when the temperature drops back down.
Baffled vents are designed to exhaust damp air out of the home, but this air is fanned from the rooms in the home like the kitchen and bathroom. It’s not recommended to have that moisture empty into the attic as it can cause mold. You could choose to vent it out the side of your home or through the roof.
