Static roof vents encourage natural airflow and enhance the overall comfort of your home by providing escape for hot, stale, and moist air which can reach temperatures of 150 degrees in summer or hotter depending on where you live.

Where should static roof vents be placed?

Place all the roof vents on the same side of the roof. If your roof peak runs parallel to the street, put them on the backside, where they’ll be less prominent. Space attic vents evenly and mark the locations by driving nails up through the shingles (Photo 1).

How many static roof vents do I need?

How Many Vents Do I Need? The general rule of thumb in these situations is of roughly one vent per every 300 square feet of attic area if the attic has a vapor barrier. If not, there should be one vent for every 150 square feet. You will need to have 1 square foot of vent area for every 150 square feet of attic space.
