Roof Ridge Vents And Gable Vents

Ridge vents are installed on the peak of the gable roof.

Roof ridge vents and gable vents.

The best system is a combination of ridge and soffit units. Now your question is. When the wind is perpendicular to the gable the cooler outside air enters the gable vent and drops to the floor of the attic before rising to exit at the other end again leaving zones of dead air right. What about the gable vent.

And then so the positive pressure at the soffit goes under the sheathing goes out at the ridge. Combining soffit vents and your gable vents this should provide enough air circulation in your roof to keep the temperature and humidity down. What are ridge vents. The problem of using more energy to cool down your roof that should in theory be saving you money on energy costs can be reduced by installing solar panels that would power fans in your roof.

Installing the vents can become a major production. I added a attic fan 1500cfm onto the gable but i have the airflow coming in from the outside instead of pushing air out. I ve read that adding a vent fan to the gable with ridge vent is bad b c it may reverse the natural flow of hot air plus draw in rain. However any airflow is better than none.

They allow airflow while directing rain away from the attic space. I have ranch house that has ridge vent soffit vents and two gables. Ridge models run the length of a roof s peak and allow warm moist air to escape soffit vents run along the underside of eaves and enhance airflow by allowing it to enter from outside roof and gable versions provide a single point of exit and entry for air. Gable vents are usually chosen for their visual appeal but can also serve as an exhaust vent.
