The attic ventilation system is divided into two parts – intake vents and exhaust vents. Intake vents are those through which the air enters the house, whereas exhaust vents are the ones which permit the humid, hot or stationary air to go out. Intake vents help the attic stay cool in summer and warm in the cold season.
As far as intake vents are concerned, homeowners should always verify if the eaves vents are properly installed and working properly.
It is very important for your attic to have adequate ventilation. This can be done in two ways: either naturally, namely using the wind effect and the stack effect, or mechanically, which means that a power source is needed.
Intake vents are placed along the soffit. They allow fresh air to enter the house. There are 3 types of intake vents:
- Gable – can be found on the siding or beneath the peak of the roof
- Static – composed of a metal cylinder, a roof jack and a metal hood, which have the purpose of preventing water infiltration;
- Soffits – offer better air circulation all year round.
Exhaust vents are installed in the upper part of the roof and can be either static, or power ventilators, which are, in fact, turbine based vents. It’s best to have those experienced in roofing Dallas TX homes to come out and inspect the roof as well as the soffits and vents.
