Gable vents are usually installed on the exterior wall of your attic in order to create proper air circulation during extreme climate conditions. In months of intense weather, the inside of your house can be regulated with heating and cooling systems.
While gable vents do not involve dismantling the roof, they do require cutting through your home's siding and the underlying plywood sheathing.

If your home has gable vents but unvented soffits, the installation of soffit venting will be a great improvement over gable vents alone.
I'd like to know whether it would be better to add gable vents or through the roof type vents. I'm thinking the gable vents would allow better airflow through the attic and might help it cool down better during the summer.
Many houses have only gable vents in the sides. These type of vents are not particularly effective for exhausting the hot air. The best type of roof ventilation is a combination of soffit vents and a ridge vent along the entire length of the roof.
If your attic uses soffit vents at the bottom and gable vents at the top for ventilation, having a gable vent fan drawing air into the attic would not be the best solution. Read on to find out more.
