The 14 inch Pop Vent Roof Louver is for ventilating steep slope roofs. PV-14-C1 is a 14 inch diameter roof vent with a 1 inch tall collar. To clarify, this vent has 1 inch of clearance between the base and the inner louvers. The PV-14-C1 has 144 inches of net free area (NFA) and comes with a 19” x 19” square flange.

Where to Install:

If installed on the upper portion of the roof, no more than 1 foot down from the peak, this attic vent can go on a roof with a pitch of 4/12 or greater in all climate zones.

To determine the number of vents you may need, see our Vent Calculator.

How it works:

The Air Exhaust Roof Louver removes moisture in the winter and heat in the summer to extend the life of the building structure. It helps to keep insulation dry in the winter to prevent mold. In addition, the round design is aerodynamic to withstand wind speeds up to 200 mph.

The 14 inch Pop Vent roof louver is great for residential roof applications because of its low profile. It can also be painted to match the color of the asphalt shingles.
