The Universal Vent is a low-profile off ridge roof vent for sloped roofs or parapet walls. Can be used as both an exhaust or intake vent.
The Universal Vent is an off ridge roof vent that can act as an exhaust or intake vent. To clarify, an off ridge vent is a UV-resistant static vent suitable for installation on sloped roofs or parapet walls.
This vent is capable of installation on roofs with a pitch of 3/12 or greater. If installed on the upper portion of the roof, this vent can be used as an exhaust vent because it's engineered to allow heat and moisture to escape. However, when placed on the lower end of a pitched roof it can be used as an air intake vent similarly to a soffit vent.
This vent is also excellent for ventilating parapet walls because it will allow the buildup of heat and moisture within the wall to escape.
This vent is ideal for proper attic ventilation. The 1/8 inch opening between the horizontal louvers blades will keep out precipitation and wildlife while allowing air to move freely. In addition to its functionality, it has a low-profile design that looks pleasing on shingled roofs and parapet walls. The hooded vent design and horizontal louvers will keep out rain and snow. Powder coating is available to match the color of your roof.

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.
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.
