Attic Ventilation for Flat Roofs | Keepa Vent 6" Diameter with Curb Mount Sub-Base | Model KV-6-CMF

The Keepa Vent with Curb Mount Base product line is ideal for flat roof ventilation. AVP offers a 6-inch diameter roof vent with an 11-inch tall collar. This roof vent has an NFA of 28 sq. inches and a curb mount base inside dimensions of 9.5” x 9.5”, designed for a square-shaped roof curb with an outer dimension of 9 3/8" x 9 3/8" unless the roof curb is covered in roofing material. Before the roofing material is added, the curb should measure 9-inch x 9-inch.

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

The 6-inch Keepa Attic Vent with Curb Mount Base is for ventilating low-slope or flat roofs and is 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, and TPO roofs, making it compatible with 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 6-inch Keepa Attic Vent with Curb Mount Base 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.

This roof vent is ideal for installation in all climate zones and comes in various sizes with an optional curb mount flange for covering roof curbs or a tailpipe adaptor for ventilating a duct.

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, the numbers shown below are 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.
