Best Way To Vent Your Attic

Attic ventilation works on the principle that heated air naturally rises primarily utilizing two types of vents.

Best way to vent your attic.

Here are four signs of an unventilated or under ventilated attic. If you don t see any attic vents on the roof or in the eaves you need to add some. Hot air exhaust vents located at the peak of the roof allow hot air to escape. If two different types of exhaust vents are combined for example a ridge vent and a gable louver the primary path of air becomes the distance between the two types of exhaust vents.

For this kind of system you need soffit vents and ridge vents. Intake vents located at the lowest part of the roof under the eaves allow cool air to enter the attic. A hot ceiling tells you that the attic is acting like a solar oven. These vents allow outside air to enter the attic at the lowest point of the roof along the underside of the eave.

The best form of attic ventilation for your home is a balanced system where the intake vents are separate from the exhaust vents. Maybe it s possible to install a gable vent lower in the attic space. When it comes to the best way to cool attic with or without an air conditioner you need to. That path is supposed to be from low in the attic intake vents to the highest possible exit point in the attic exhaust vents.

Soffit vents are intake vents located under the outside eaves of your home. Ridge vents which run along a roof s peak and gable vents installed at the gable ends of the attic cancel each other out. The soffit vents allow convective air movement from the soffits of the residence to the ridge vent. Ridge vents are the exhaust vents that are located along the ridgeline of your roof.

Look at your eaves and roof. Touch your ceiling on a warm sunny day. Indoor air conditioning unit. If your home is fitted solely with small gable end vents or a ventilator high in the roof you might want to consider adding soffit vents to increase airflow.

In addition insulation baffles must be installed at the point where the attic floor meets the roofline to prevent the attic insulation from migrating into the cavities and restricting the airflow from the soffit vents.
