4 inch Keepa Roof Jack Vent Cap | 4 inch Roof Vent with Tailpipe | Model KV-4-TP

AVP offers a 4 inch diameter commercial roof jack vent cap with an 11 inch tall collar and a curb mount flange as well as a 2 inch tailpipe that is for duct ventilation. It's ideal for ventilating bathroom fans and range hoods. It allows for maximum airflow while alleviating back pressure.

The 4 inch Keepa Roof Jack with curb mount flange will prevent insects and wildlife from entering the duct. It will also prevent rain or snow from entering inside in all climate zones. The 11 inch tall collar height is great for low slope or flat roofs.

These roof vents have an all-aluminum construction. To clarify, this means they are durable, lightweight, and will not rust.

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

The 4 inch vent is ideal for installation on low slope or flat roofs.

The Roof Jack’s tailpipe is approximately 2 inches long and is corrugated at the bottom to fit existing ductwork. This allows for a quick and easy installation. In addition, the head of the roof vent is removable, therefore allowing easy access for easy installation on EPDM, TPO or PVC roofs. In addition, this attic vent is compatible with membrane roofs.

How it works:

The tailpipe allows for easy installation to existing ductwork. This vent is ideal for ventilating bathroom fans and range hoods.

The 11 inch tall collar is suitable for locations that accumulate high levels of snowfall. In addition, the round design is aerodynamic to withstand wind speeds up to 200 mph. Most importantly, the Keepa Roof Jack comes in an array of sizes with an optional curb mount flange for additional clearance or flat flange flashing.

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.
