What do Roof Exhaust Vents do?

Roof exhaust vents remove hot and moist air from the attic. This benefits the attic because it supports dry insulation. Dry insulation provides energy saving all year long.

Where do Roof Exhaust Vents get installed?

In order for roof exhaust vents to work efficiently they must be located at or near the peak of the roof because that’s where the moist hot air rises.

What type of Roof Exhaust Vent should I use?

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, which is why AVP offers to assist all customers with their roof vent choices.

What if I can’t find the Roof Vent I’m looking for?

All roof vents are customizable. Choose your color, diameter, height, curb mount flange and or tail piece adapter for ducted systems.

What if I have a flat roof?

Vents manufactured for a flat roof tend to be built differently than vents for a steep pitched roof. The main difference between the two is the height of the roof vent. Vents for a flat roof need to be built taller than vents for a pitched roof. AVP offers vents for both roof types.

Look at the Importance in Installing Roof Vents during the Hot 2021 Summer Season

Your roof and attic need must be properly ventilated in order to improve the air temperature and humidity levels so that you can uphold the guarantee that your home will be energy efficient. Both heat and moisture can threaten the very warrantee and life of your roof. By installing roof vents along the guidance of IBC, the damaging and costly elements of heat and humidity will be released out from your home or building.

Without proper ventilation, you may experience a variety of problems with your home:

Elevated energy costs

Prolonged heat causing damage to roof systems

Possible mold, mildew or even dry rot to the attic structure

Lost energy effectiveness because insulation is wet

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 the problems mentioned above. Roof vents are fairly inexpensive but can have a huge impact on your bottom line. For most people owning a home is the biggest investment they will ever make, venting your home not only makes sense, but it also makes your home a healthier place to live.

For over 30 years we have focused our engineering and creative prowess to make the best roof vents possible.

But our heart and passion has always been staying connected to our staff and customers. Helping others and giving back to our local community has always been our greatest accomplishment.

In May of 2019, AVP’s president Martin Kolt began shooting informational roof vent videos like his brother Ethan. The goal in making these videos is to help answer questions many customers have about roof vents and to also support technicians out in the field. It is important that Martin shares his knowledge with AVP’s customers. After all, Martin has been supporting the roof ventilation industry for over 30 years. At work Martin with his team engineer better roof vent designs and also find new and innovative ways to help the end-user. Martin discovers ways to manufacture more efficiently and safely for his team. When Martin is not working on roof vent and roof vent accessory designs, he also acts as corporate liaison with Underwriters Laboratories (UL)Texas Department of Insurance, and Florida State. Martin and Ethan are planning on releasing more videos later this year, with the goal in mind to create a video library of valued information that will be easily accessible. Martin and Ethan’s videos are available for viewing on AVP’s websiteFacebook and AVP’s YouTube channel.

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. This is done because powder coating paint lasts longer than conventional wet paint. How do you powder coat roof vents? First, roof vents are sprayed with a special magnetic paint powder that sticks on to their surface. 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 fresh painted look. Once the roof vent cools, the paint cures and hardens. This process will make the painted roof vents look like new for many years longer versus if they were painted with wet paint.

Commercial Gravity Ventilators & Industrial Roof Vents

 

Flat Roof Ventilation is the removal of hot air and moisture that collects in attics or plenums. Roof Vents need to have the proper vertical height requirements in order to be used on flat roofs. You typically need a roof pitch under a 3/12 to be considered a flat roof.

Some roof vents may need a curb mounted flange, if the roof vent is going to be installed on top of a roof curb. Flat roof ventilation is a niche that Active Ventilation Products (AVP) has supported and supplied for many years. AVP ensures that its roof vents and roof accessories install easily on membrane roofs and once installed, can add years of life to a roof membrane. AVP’s flat roof vents are manufactured specifically for flat roof ventilation. All flat roof vents including air intake vents and air exhaust vents are used together for balanced roof top ventilation.

Off Ridge Dormer Vents

The Universal Dormer Vent is a low profile off ridge roof vent that is designed for a pitched roof of 3:12 slope or greater. The Universal Dormer vent can be used as an air intake vent or as an air exhaust vent depending on where you install it on the roof.

The Universal design looks great on a shingle roof. When used as an exhaust vent, it is installed near the peak of the roof, where it allows heat and moisture to escape the attic. When placed at the low portion of the roof, it can be used as an air intake vent, similar to a soffit vent where it will allow in cool fresh air. UL listedTexas Department of InsuranceFlorida State listed and has CAL FIRE.

In order to exhaust air, you need a fresh air intake!

Attic Vents, Roof Louvers and Static Vents that bring in fresh air to your attic enable your roof exhaust vents to work efficiently. This is accomplished by when you bring in fresh air to your attic or plenum you also pressurize that space so that there is air available to flush out the heat that can now escape through your roof exhaust vents. All commercial air intake roof vents have the vertical height requirement for flat roof ventilation and can also be made with a curb mount flange if your roof vent needs to be installed onto a roof curb. Roof vents can be made to connect to a duct with a tail piece adapter if you need make up air to a duct system as well. All roof vents have an aluminum construction; therefore they will not rust and are UL certifiedTexas Department of InsuranceFlorida State Approved and have CAL FIRE.

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.

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.

Roof Ventilation for Steep Slope

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

(Source: ResearchGate)

Below are some common types of roof exhaust vents:

Roof Vents diagram of Heat and Moisture flow in an attic

Static Vents

Static Vents 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 image 

Turbine Vents

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)
