How big of a gable vent do I need?
Divide your total square footage by 300 to determine the vent area. Typically you want a vent area of one square foot for every 300 square feet of attic space. When dividing, round up to the next whole number. In the example, you want 3 square feet of vent area.
Where should a gable vent be placed?
Gable vents are installed in the gabled ends at opposite ends of the attic. They’re most effective when the vents align with the prevailing winds. This allows high air pressure on the upwind side of the home to push air into the attic, and low pressure on the downwind side to pull air out.
Should you cover gable vents in the winter?

Is it possible to have too much attic ventilation?
It’s possible to have too much exhaust ventilation, but you cannot have too much intake ventilation. If there is more intake ventilation than the attic’s square footage requires, it’s not problematic because any excess intake converts to “exhaust” on the leeward side of the house.
Do gable vents let in rain?
According to experts, here’s what you need to keep the rain out of your gable vent. The most effective way to prevent rain from slipping through your vent is to add a baffle piece that allows air to move but prevents water from entering. You can also add a deflector to redirect rainwater.

Are gable vents intake or exhaust?
When prevailing winds blow perpendicular to the vents, the gable vents act as both intake and exhaust. Less air exchange takes place and attic ventilation is not uniform, so it’s less effective. Roof vents, sometimes called “turtle” vents, should be installed near the roof peak.
How much does it cost to install a gable vent?
Gable Vent Replacement Cost The replacement price of a gable vent averages between $10 and $60 but can be up to $150, depending on the style you choose. The price of a carpenter to replace or install a gable-mounted unit is about $70 an hour.
Can rats come through roof vents?
Rats are excellent climbers and are capable of gaining entry through holes around soffit vents, around cables entering the building, through holes in gable vent screens and through turbine and box vents on roofs. Many garage doors on homes allow enough space for rats to fit underneath, as well.
