Proper ventilation is crucial for maintaining the longevity and health of any roofing system, especially in the case of flat roofs. Flat roofs with a pitch of 2/12 or less require specialized ventilation to remove excess moisture during the winter and heat during the summer. One effective solution to ensure adequate ventilation for flat roofs is the installation of Keepa Attic Vents. These vents, approved by Miami-Dade County, offer a range of benefits that help extend the lifespan of the roof membrane and improve overall energy efficiency.

These vents are equipped with collars of varying heights, with 3-inch vents having a 7-inch tall collar and vents from 4 to 12 inches in diameter featuring an 11-inch tall collar. The 11-inch collars are designed to withstand all climate zones' demands.
The round design of Keepa Attic Vents enhances their aesthetic appeal and enables them to withstand wind speeds exceeding 200 mph. This durability ensures the vents remain functional and intact even during extreme weather conditions.

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.
