One of Our Premier Roof Vents: The Pop Vent

The Pop Vent Roof Louver is for ventilating steep slope roofs. The roof louver removes moisture in the winter and heat in the summer to extend the life of the building structure. As a result, it helps to keep insulation dry in the winter to prevent mold. During the summer it removes heat and humidity. In addition, the round design is aerodynamic to withstand wind speeds up to 200 mph.

The 1/8 inch opening between louvers will prevent rain, snow, insects and animals from entering inside the vent. The vertical louvers will work better than insect screens by allowing air to freely flow in and out of the roof vent. This allows for proper attic ventilation.

The Pop Vent comes in an array of sizes and collar heights to fit the need of every roof. In addition, AVP offers roof louvers as Air Intake vents as well.

This roof vent's lid is one solid piece of aluminum. Thus making this roof vent both durable and corrosion resistant.

This roof louver has been installed in over 1 million homes since it debuted 35 years ago. To determine the number of vents you may need, see our Vent Calculator.

The diameter size of all roof vents determines the Net Free Area, also known as the "NFA". NFA is the measured amount of opening each vent offers at each specific size. to be available for venting air through a specific vent size. The calculator below will find the overall number of vents needed to effectively ventilate the targeted attic space.

Once you have the area, pulldown to select the specific vent diameter to show the number of vents of that size which would ventilate the specified area with both 1/300 and 1/150 rule.

*Please note
The roof vent calculation values shown above are for the exhaust portion of the roof. The same amount of net free air inches is needed for air intake as well. Proper roof ventilation consists of 50% air exhaust and 50% air intake.
