AVP’s roof vent lines make for excellent exhaust roof vents and air intake roof vents. The names of these lines are: Aura Vents, Round Back Vents, Keepa Vents, Pop Vents, Witches Hat and Universal Vents. AVP also supplies vents for a duct system. These lines are the Round Back Roof Jack Vent Caps for pitched roofs and Keepa Roof Jack Vent Caps for flat roofs. All roof jack vent caps come with a tailpipe adapter so that they can easily attach to rigid or flex duct. They are great for ventilating bathrooms, dryers, or other specialized roof jack applications.
All Active Ventilation’s roof exhaust vents remove hot air out of the attic and should be installed near the top of the roof. Being near the top of the roof allows for the build up of heat and moisture to escape the attic.
There are many exhaust vents to choose from, that’s why AVP offers to assist it’s customers in deciding which exhaust vents are best for their roof ventilation project, especially since all roof vents are available with optional collar heights and Curb Mount Flange for when you need to install your roof vent on top of a roof curb: Aura Vents with Curb Mount Flange, Round Back Vents with Curb Mount Flange and Pop Vents with Curb Mount Flange for example.
Our Intake Pop Vent – Here a PV-20-C12.
Group of soffit vents, width of 10in.
Ventilation must be balanced, or air will not move. Exhaust roof vents are only half the picture. Intake roof vents are generally used to bring in cool, dry air near the lowest point of an attic. This creates an air flow. Gravity causes the warmer air to rise, expelling the wetter air out of the exhaust roof vents near the top of the roof. Our Vent Calculator is the perfect tool to determine the number of intake and exhaust roof vents needed. Our intake roof vents include Round Back Vents, Keepa Vents, Pop Roof Vents, Universal Vents, and Soffit Vents.
These vent product lines are also available with Curb Mount Flanges, which facilitate installing the vents on a roof curb: Round Back Vents, Pop Vents,

Our Aura Attic Fans (Sometimes referred to as “Power Vents“) use powerful fans to keep your attic ventilated in any season, day and night.
Our Aura vent head, used in our Aura Attic Fans, actively exhaust even when the fan is not turned on, due to the unique shape of the Aura vent head louver design. Even a small breeze is enough to activate the venturi effect, which creates a suction to draw air up and through the vent head.

The Aura Solar Attic Fan (Sometimes referred to as a “Solar Power Vent“) uses both solar and wind power for optimum ventilation performance, day and night.
The solar panel wattage is over-sized to the fans at a rate of 2 to 1. This results in Cubic Feet per Minute (CFM) production at angles up to 80 degrees. Even during evenings and cloudy days when the solar panel is not hit by sunlight, the inner and outer vertical louvers around the fan allow air to exhaust passively.
Aura Solar Attic Fans are also available with Curb Mount Flanges, ready to install on roof curbs. We also sell Round Back Solar Fans.

Roof Jacks Vent Caps
For Duct Ventilation
Our Roof Jacks are excellent for venting out a bathroom fan or other duct applications.
Made of rust free aluminum, with a 2 inch tail pipe (adapter) to fit existing duct work. The inner vertical louvers of the roof vents act as an insect screen, keeping out wildlife while allowing air to flow without resistance. Its superior design also rain and snow from entering, as the top is not open to the sky. Having a round design makes the vent aerodynamic, which allows it to deflect wind an objects carried by the wind. The low profile and round design of the residential roof jack vent cap is appealing to the eye and with various color options your home will look beautiful. The commercial roof jack vent cap has a standard 11 in. collar height, great for a flat roof install, especially in areas with high rain or snow fall.
Residential Off Ridge Vents
The Universal Vent, a low profile off ridge roof vent, designed for steep sloped roofs that can be used for air intake vent and or exhaust.
This design looks great on a shingle roof & it can also be used on a a parapet wall that surrounds a flat roof. When used as an exhaust vent, it allows heat and moisture to escape on the upper portion of the roof, & when placed at the low portion of the roof, it can be used as an air intake vent, similar to a soffit vent.
Commercial Roof Vents & Industrial Roof Vents
Attic Ventilation – Air Intake Vents for Low Slope & Flat Roofs.
In order to exhaust air, you need intake air! Our line of intake roof vents allow your exhaust vents to work efficiently, by bringing in fresh air as your exhaust releases the hot air.

Why Install Roof Vents? (Frequently Asked Questions)
What is roof or attic ventilation?
The goal of roof ventilation is to provide a means of allowing outside air to enter and exit attics and ventilated spaces, so that heat and moisture can leave the building envelope.
What is a roof vent?
A roof vent is an engineered structure that is typically rigid and has two primary functions. First, to allow air to travel through it, and second to prevent insects, rain, snow and any wind-blown debris (including burning embers) from passing through it.
What is a roof vent used for?
Roof vents are used for the purpose of air intake and air exhaust. Having vents of both types installed is required by IBC International Building Code and all local municipalities for steep slope roofs.
What are (air) intake roof vents?
Air intake vents are used to allow outside air to enter into attics. Intake vents should be located low on the roof, or along the lowest eave or soffit of the roof assembly. Intake vents are best when used in conjunction with roof exhaust vents.

Below are names and pictures of commonly used air intake vents:
- Off ridge vents
- Individual soffit vents
- Roof Louver
- Static Vents are non-motorized roof vents
- Passive Vents are non-motorized vents
Common problem with soffit vents (most popular air intake design)
All intake vents should be installed on the low end of the roof or under the eaves. Since soffit vent are installed under the eaves they run the risk of being blocked off on the interior side of the vent by attic insulation. This problem can be averted by doing a visual inspection of the attic from the inside to make sure that all soffit vents are not blocked off by insulation, storage items and or other materials.  original image
Another way to avoid soffit vents from being blocked is to install baffles. Baffles are placed between rafters keeping insulation from blocking air from the soffit vent below.  original image
In general intake vents should be designed and installed to prevent precipitation, animals and insects from entering the attic space.
NRCA does not recommend the use of drip edge vents as intake vents in northern climates where there is a likelihood of ice damming.

What are roof exhaust vents?
Roof exhaust vents allow for hot air from the attic below to pass through them so that heat and moisture go directly to the outside, leaving the building envelope completely. In order for roof exhaust vents to work efficiently they must be located at or near the roof peak since hot air rises.
What is roof ventilation (for steep slope)?
Proper roof ventilation consists of air intake at low points and air exhaust on the high points of the roof. This design system works off of nature’s thermal dynamic, a process called Diurnal Convection.  original image

Below are some common types of roof exhaust vents:
Static Vents:Â Are roof vents that are non-motorized vents can be used as a roof exhaust vents or roof intake vents depending where on the roof they are installed. For roof exhaust they are placed near the peak of the roof and for intake they are placed on the lower portion of the roof.
Below are pictures of common static roof vents also called passive roof vents and gravity roof vents.  original imageÂ
Turbine Vents:Â Turbine vents and other similar vents rely on wind to rotate the turbine’s fan blades. The spinning of the blades by design rotate to keep out rain and snow, not to expedite the ventilation capacity like may people believe. (Source: NRCA)
