Roof Vent | 4-inch Keepa Attic Vent | Model KV-4

The Keepa Vent product line is ideal for flat roof ventilation. AVP offers a 4-inch diameter roof vent with an 11-inch tall collar. This roof vent has an NFA of 12 sq. inches and a standard 10” x 10” square flange.

Installation: Best on flat roofs, no more than 2/12 pitch

The 4-inch Keepa Attic Vent is for ventilating low-slope or flat roofs. It's typically used for ventilating attics and plenums as a roof exhaust vent or air intake roof vent. The removable vent head allows easy installation on EPDM, PVC, or TPO roofs. This roof vent is compatible with all membrane roofs. Click here to view our installation guides.

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

How it operates:

The 4-inch Keepa Attic Vent removes moisture from the attic during the winter and heat during the summer, extending the life of the building structure. The 11-inch tall collar is suitable for all locations, including those that accumulate high snowfall. In addition, the round design is aerodynamic and can withstand wind speeds beyond 200 mph.

The Keepa Attic Vent is ideal for installation in all climate zones and comes in various sizes. It has an optional curb mount flange for covering a roof curb or a tailpipe adaptor for ventilating a duct.
