One of Our Premier Roof Vents: The Pop Vent
The Pop Vent Roof Louver is used for ventilating steep slope roofs. The Air Exhaust 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 is designed to prevent rain, snow, insects and animals from entering inside the vent. The vertical louvers have been engineered to 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 different diameter sizes and collar heights to fit the need of your roof. On the other hand, we have Pop Vents as Air Intake vents as well.
The Pop Vent 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.

All of AVP's Pop Vents are UL Listed and rated up to 50+ PSF or wind pressure above 200 MPH. Certified by Texas Department of Insurance, Florida State Approved & Conforms to the Standards of CALFIRE.
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.
