Roof vents will provide proper circulation, therefore, making homes energy-efficient. AVP has exhaust vents for both flat roofs and pitched roofs. We carry an array of vent models; for example Aura Gravity Ventilators, Round Back Static Vents, Keepa Attic Vents, Pop Vents and Universal Vents.
All Roof Vents are available with Curb Mount Flanges as well as corresponding roof curbs.
For duct ventilation, we have 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 for easy installation. All roof jacks are ideal for ventilating bathroom fans and range hoods.
Roof exhaust vents remove heat and moisture from the attic during the summer. In addition to removing moist damp air during the winter. This benefits the attic because it will keep dry insulation. Dry insulation prevents mold and mildew from growing.
In order for roof exhaust vents to work efficiently, they must be located near the peak of the roof. This is because hot air rises and will naturally collect near the peak.
There are many roof exhaust vents to choose from, and choosing the right one may seem difficult. After all, not all roofs are built the same. This is why AVP offers to assist all customers with their roof vent choices.
All roof vents are customizable. Choose your color, diameter, height, curb mount flange and/or tailpiece adapter for ducted systems.
Vents manufactured for a flat roof tend to be built differently than vents for a steep pitched roof. The main difference is the height of the vent. Vents for a flat roof need to be built taller than vents for a pitched roof. AVP offers vents for both roof types. For more information on roof exhaust vents for flat roof applications please click on: Aura Vents, Aura Vents with Curb Mount Flanges, Round Back Vents with Curb Mount Flanges, Keepa Vents and Witches Hat Vents.
In order to achieve proper attic ventilation, there needs to be a balance between Exhaust and Intake Air. The intake of air will allow the hot humid air to escape through the exhaust vents at the peak. Air intake vents are available for both flat roof and pitched roof ventilation. Roof Vents can also be made with a curb mount flange for installation on roof curbs. All roof vents are UL certified, Texas Department of Insurance, Florida State Approved and have CAL FIRE. In other words, these vents can withstand wind speeds up to 200mph
The Aura Attic Fan exhausts air for proper attic ventilation. This fan will exhaust air continuously even when the motor is off. It also works passively because of the Venturi Effect. This occurs when the wind blows against the outer louver to create an upward draft. As a result, allowing air to freely flow in and out. Aura Attic Fans remove hot humid air during the summer and moist damp air during the winter. This not only keeps the insulation dry but will lengthen the life of the roof.
AVP's solar fans are built for installation on pitched roofs, flat roofs and roof curbs. Each line of Solar Fans come in an array of sizes and collar heights allowing for installation in all climate zones. The solar panels work best in bright direct sunlight. However, it exhausts air continuously even when there is no sun and the motor is off. These solar fans are designed to remove hot air from the attic in the summer. In addition, they also remove moisture during the winter. As a result, this allows for year-round ventilation. The 1/8 inch louvers are designed to prevent rain, snow, insects and animals from entering inside the fan. The all-aluminum construction allows for a rust-free and durable fan.
The Round Back Roof Jack Vent Cap is made for steep-sloped roofs; while on the other hand, the Keepa Roof Jack Vent Cap is designed for flat or low sloped roofs. Both roof jack vent caps are ideal for ventilating bathroom fans and range hoods. All roof jacks are made of rust-free aluminum and come with a 2-inch tailpipe. The tailpipe can be attached to the rigid or flex duct. The inner vertical louvers not only ventilate the duct efficiently but also act as an insect screen. The round aerodynamic design allows the vent to deflect wind and debris. Both Roof Jacks come in an array of sizes allowing for installation in all climate zones.
Proper ventilation will remove excess heat during the summer and moisture during the winter. As a result, extending the life of the roof and the efficiency of the HVAC systems. In addition, having a balance of exhaust and intake air will keep insulation dry. Having proper roof ventilation is beneficial in all climate zones. For exhaust vents, we recommend our Aura Gravity Ventilators as they come in an array of sizes. For intake air, we have Pop Vents and Soffit Vents to balance your attic ventilation.
Proper ventilation will be accomplished when you have equal amounts of air exhaust with air intake. Exhaust vents should be placed on the upper portion of the roof, meaning no lower than 2ft from the peak. While on the other hand, air intake must be on the lower end of the roof.
With over 24 years of experience, we know how to manufacture ventilation. We harness the force of nature to circulate air in your home. The following pages will help to explain the different types of ventilation systems. Each will help explain how to keep your home cool with your type of roof.
This installation had pre-installed wooden roof curbs. The Pop Vent was installed in just a few minutes and was done right before a major rainstorm. To the left and bottom, you can see the Pop Vent installed. The bottom image shows the inside of the wooden roof curb. To the right is AVP's Aura Gravity Vent which is ideal for exhausting air. In order to have proper ventilation, you will need a balance of intake and exhaust air.
A pitch pan is a flanged, open-bottom, metal container that wraps around roof penetrations. They are then filled with mastic material to provide a water-tight seal. In other words, a pitch pan is a retrofit roof flashing kit. Also known as a pitch pocket, they function as a container to hold fluid sealant to seal all roof penetrations. They effectively secure odd-shaped penetrations to prevent leaks. Some of these roof penetrations may include electrical conduit, I-beam support, or plumbing.
Pitch pans – pitch pockets are used to flash roof penetrations that would be difficult to flash in any other way. They have been designed to work with all roof types such as TPO, PVC, and EPDM. Pitch pans are also used with all HVAC systems to ensure a leak-proof seal. AVP’s pitch pocket will prevent leaks from occurring right at the roof penetration. The open pitch pocket design is ideal for wrapping around electrical conduit, I-beam support, and plumbing. This allows for easy installation while eliminating the risk of leakage.
AVP’s pitch pan shapes also vary from square boxes to rectangular boxes. Square pitch pockets are ideal for containing single penetrations; while on the other hand, the rectangle pitch pockets are made to contain multiple small penetrations close together. As a result, every customer will be able to find a pitch pocket to fit all roofing needs.

Immigrating from Honduras 12 years ago, this father and grandfather works tirelessly at Active Ventilation Products to ensure that orders ship on time. His work ethic, positive attitude and friendliness to others at the factory is greatly valued as he is one of AVP’s key members.
The Pop Vent is more than a roof vent; it's also a cool way to ventilate a really fun art project. Los Angeles-based composer, Chad Fischer, built a replica Apollo 11 Space Capsule in his garage during quarantine. This incredibly beautiful and realistic model was built as a playhouse for his daughter.
Chad installed the Pop Vent to ensure that his child played in a safe well-ventilated space. He also knowingly chose The Pop Vent because of its aerodynamic shape; he knew it would make for a great looking installation.
This playhouse will be protected by the Pop Vent for years to come because it withstands wind speeds in excess of 200 mph while also keeping out wildlife, insects and rain.
To the right, you see images of this one-of-a-kind playhouse as well as part of the assembly process.
Proper attic ventilation is important during the hot summer months. Without it, heat and moisture can get trapped in the roofing system which could cause decay of the structure. To achieve proper attic ventilation, you need both exhaust and intake air. This will remove excess heat and humidity from the attic, ultimately lowering energy costs. In addition, the intake air will keep the attic cool.
Every roof should have exhaust vents along the peak and air intake vents towards the bottom. We also have soffit vents for under-eave installation to minimize the look of bulky ventilators.
Elevated energy costs
Prolonged heat causing damage to roof systems
Possible mold, mildew or even dry rot to the attic structure
Damage occurring because trapped water is on the wood deck, rafters and possibly sheetrock below
Condensation will cause rust and corrosion of metal nails, straps and HVAC ducting clamps amongst other things
Having roof vents for air intake and air exhaust can alleviate all of these problems. Roof vents are fairly inexpensive but can have a huge impact on your home. For most people, owning a home is the biggest investment they will make. Therefore, venting your home is not only important, but it also makes your home a healthier place to live.
In May of 2019, AVP’s president, Martin Kolt, began shooting informational roof vent videos. The goal is to help answer frequently asked questions about roof vents. In addition, these videos also support other technicians out in the field. It’s important that Martin shares his knowledge with AVP’s customers. After all, he has been supporting the roof ventilation industry for over 30 years.
At work, Martin and his team engineer better roof vent designs and also find new and innovative ways to help the end-user. He has discovered ways to manufacture vents more efficiently and safely for his team.
When Martin is not working on roof vent designs, he acts as corporate liaison with Underwriters Laboratories (UL), Texas Department of Insurance, and Florida State. Martin and Ethan plan to release more videos later this year. The goal is to create a video library of valuable information that will be easily accessible. Their videos are available for viewing on AVP’s website, Facebook and AVP’s YouTube channel.
This Round Back Static Roof Vent is 3 inches in diameter and is used for a wide variety of applications. Some of which are bathroom fans, plumbing ventilation or range hoods. Shop roof vents at AVP.
AVP's roof vents vary in size from 3 inches in diameter to 48 inches. While on the other hand, the collar heights range from 1 inch to 12 inches. As a result, all roof vents have been engineered for every climate zone and can be customized for all types of roofs. Some roof types may be EPDM, TPO, PVC, asphalt shingle, cedar shake, slate, or tile. AVP serves the residential, commercial, and industrial roofing sectors.
Exhaust Roof Vents remove hot air from the attic in the summer and moisture from the attic in the winter. Roof Ventilation extends the life of your roof and can make your home or building more energy efficient. AVP form’s its roof vents out of heavy gauge aluminum so that they can hold up to the toughest weather conditions. Roof Exhaust Vents are manufactured to handle different climate zones. Roof pitch is a factor when deciding which roof vent to purchase.
AVP’s Roof vents are painted by powder coat instead of applying wet paint. Powder Coating lasts longer than conventional wet paint. How do you powder coat roof vents? First, roof vents are sprayed with a special magnetic paint powder. Then the roof vents are baked at 400 Degrees Fahrenheit for 15 minutes in an industrial oven. The baking process melts the paint powder giving the roof vent a freshly painted look. Once the roof vent cools, the paint cures and hardens. This process makes the painted vents look new for longer versus if they were painted with wet paint.
Attic ventilation is important as it can help maintain the health of the building. Removing unwanted heat in the summer and excess moisture in the winter will help the life of the roof. This will also help the functionality and efficiency of the HVAC systems. Flat roofs are considered anything under a 3/12 pitch. Here at AVP, we design our vents specifically for low slope or flat roofs. These vents typically have a taller collar and/or come with a curb mount flange for installation on roof curbs. The additional height prevents precipitation from entering inside the vent. In addition, this will protect the attic from unwanted moisture.
The Dormer vent can be used as an air intake vent or as an air exhaust vent. If installed on the upper portion of the roof, this vent can be used as an exhaust vent. This vent is engineered to allow heat and moisture to escape. However, when placed on the lower end of the roof it can be used as an air intake vent similarly to a soffit vent. The off ridge roof vent is also excellent for ventilating parapet walls because it will allow the buildup of heat and moisture within the wall to escape. Above all, the Dormer Vent is ideal for proper attic ventilation.
The 1/8 inch opening between the louvers will keep out precipitation and wildlife while allowing air to move freely. In addition to its functionality, it has a low-profile design. This allows the vent to look pleasing on shingled roofs and parapet walls. Powder coating is available to match the color of your roof. These vents are UL listed, and meet the standards of the Texas Department of Insurance, Florida State and have CAL FIRE approval.
In order to exhaust air, you need a fresh air intake. Roof Louvers and Static Vents that intake fresh air to the attic allow exhaust vents to work efficiently. This pressurizes the space so that there is air available to flush out. As a result, the heat can escape through the exhaust vents. All commercial air intake roof vents have a vertical height requirement for flat roof ventilation. As a result, our vents can also be made with a curb mount flange. Curb mount flanges are only necessary if being installed onto roof curbs. Roof vents can be made to connect to a duct with a tailpiece adapter if connecting to a duct system. All roof vents have an aluminum construction; therefore they will not rust.
Soffit Vents made are with a Multi Louver Design for optimal fresh air intake for the roof.
Soffit vents are essential for proper attic ventilation. In order to exhaust heat from your roof, you need a soffit vent to bring in the cool dry air. The Under Eave Vent is an air intake roof vent. To clarify, Soffit Vents are roof vents installed underneath the eaves of a roof that extend past the warm wall line. When properly combined with other roof ventilation devices, soffit vents allow fresh air to enter into an attic to create proper airflow.
At first, it may seem odd to add insulation for warmth then purposely allow cold air to enter the attic through soffit vents. On the contrary, attic ventilation is the key to an energy-efficient home. Allowing a natural flow of air to ventilate the attic helps the attic properly ventilated. As a result, this prevents mold from growing and keeps the insulation dry. In addition to intake air, you will also need to exhaust out the stale air from the attic. See our Exhaust Vents to complete your attic ventilation.
Our all-aluminum Under Eave Vents are corrosion-resistant and easy to install. All vents are available in a wide variety of colors. The 1/8 inch louvers are designed to prevent rain, snow, insects, and animals from entering inside the vent. As a result, allowing the air to move through the vent without resistance.
Roof Jack Vent Caps are built to attach to a duct. Allowing air to exhaust out without rain, snow, or insects from getting into your home.
The Round Back Roof Jack Vent Cap is made for pitched or steep-sloped roofs while the Keepa Roof Jack Vent Cap is designed for flat or low sloped roofs. Both roof jack vent caps are ideal for ventilating bathroom fans and range hoods. The Roof Jack’s tailpipe is 2 inches long and is corrugated at the bottom to fit existing ductwork. This allows for a quick and easy installation. The inner vertical louvers of the roof jack vent caps not only ventilate your duct effectively but also act as an insect screen. Having a round design makes the roof jack vent caps aerodynamic; this allows them to deflect wind and objects carried by the wind.
It’s a great time to replace your old, noisy roof turbines with one of our roof vents, solar attic fans, or vent pipe caps. Our roof vents remove excess heat and moisture from the attic or exhaust pipe. All roof vents and accessories operate silently. As an extra upgrade have your roof vent painted to match the color of your roof or pipe.
All PVC Vent Caps and Solar Fans can be used for commercial and residential applications. Exhaust caps and solar fans are remarkable for eliminating heat and moisture. While on the other hand, the passive air intake caps allow for fresh air to enter the PVC Pipe. They will continually exhaust air with no moving parts while preventing rain and snow from entering. The vertical louvers keep out insects and animals allowing for optimal airflow. In addition, the round design is aerodynamic to withstand wind speeds up to 200 mph.
AVP offers quality attic exhaust fans that provide airflow for optimal ventilation. The fans remove hot humid air during the summer and moist damp air during the winter. This not only keeps the insulation dry but will lengthen the life of the roof. All fans have vertical louvers that prevent rain and snow from entering. in addition, these louvers also keep out insects and animals. As a result, this keeps the fan clean which allows maximum air exhaustion without resistance. Additionally, this fan has a removable top which makes it easy for maintenance on the unit.
The Round Back Solar Fan uses both solar and wind to power the ventilator. It exhausts air continuously even when there is no sun and the motor is off. It works passively because of the Venturi Effect. When the wind blows against the outer louvers this creates an upward draft which allows air to freely flow in and out of the vent. This Attic Fan is also available with an optional Shut-Off Switch.
If installed on the upper portion of a roof with a pitch of 4/12 or greater. This fan can be installed in all climate zones. If installed no more than 3 feet from the roof, it can be installed in climate zones 1-4.
The 1/8 inch louvers are designed to prevent rain, snow, insects and animals from entering inside the fan.
The Aura Solar Fan uses both solar and wind to power the ventilator. It exhausts air continuously even when there is no sun and the motor is off. It works passively because of the Venturi Effect. When the wind blows against the outer louvers this creates an upward draft which allows air to freely flow in and out of the vent.
The 1/8 inch louvers are designed to prevent rain, snow, insects and animals from entering inside the fan.
The Aura Solar Fan comes in an array of diameters and collar heights allowing for installation in any climate zone. See the Climate Zone Chart to determine the proper collar height for installation in your area.
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.
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.
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.
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
Above all, intake vents should be installed to complete attic ventilation; In addition to preventing 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.
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 are roof vents that are non-motorized. Therefore, they can be used as an exhaust vent or intake vent depending on where they are installed on the roof. If installed on the upper portion of the roof, they can be used as an exhaust vent. While on the other hand, if they are placed on the lower portion of the roof, they would be used for intake. Our most popular static vents, for example, are the gravity vents and the round back vents. Below are pictures of common static roof vents also called passive roof vents and gravity roof vents. original image
Turbine vents rely on wind to rotate the turbine’s fan blades. The spinning of the blades rotate to keep out rain and snow, not to expedite the ventilation capacity as many people believe. (Source: NRCA)
The typical whirlybird turbine vent will rust and stop working overtime. While on the other hand, our gravity vents continuously work without any moving parts.
