We are the first and only roof vent manufacturer to receive quarterly production audits on all our UL certified roof vents.

To view lab testing click on UL Certification. Testing reveals that all roof vent lines withstood wind pressure in excess of 200mph (50+ PSF).

AVP manufactures Mobile Home Roofing Products specifically for HUD, FEMA & Modular Builders. Dave Carter & Associates, AVP’s National Distributor has launched AVP’s money saving products to the market and as a result AVP is experiencing phenomenal growth.

Our UL certified Aura Vents, Pop Vents, Round Back Vents and Keepa Vents are tested to withstand wind pressure speeds up to 200 mph! These roof vents have an all aluminum construction, you will not see any rust streaks on your roof. The inner vertical louvers have an 1/8th inch diameter opening, maximizing air flow while keeping out insects and animals. Our roof vents are not open to the sky, and prevent rain and snow from entering.

Commercial Roof Vents & Industrial Roof Vents

AVP customizes commercial roof vents & industrial roof vents to architects, engineers and building specifier’s specifications. We have commercial roof vents and fans in sizes 3 inches to 48 inches in diameter, and collar heights (the neck of the vents) ranging from 1 inch to 36 inches. The depth of these product lines covers every climate zone imaginable, and at every roof pitch too.

Our Universal Vent is a low profile off ridge roof vent designed for sloped roofs and can be used as an air exhaust or intake vent. This UL certified vent withstands wind pressure speeds up to 200 mph! Its low profile design looks great on shingled roofs as well as parapet walls. When used as an exhaust vent, it allows heat and moisture to escape. When placed at the low end of a pitched roof, it can be used as an air intake vent, similar to a soffit vent.

Commercial Roof Vents & Industrial Roof Vents

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. All aluminum construction, these intake vents are maintenance free and will not rust! UL certified and tested to withstand wind pressure speeds up to 200 mph.

Residential or Commercial Soffit Venting

Our Soffit Vents are corrosion resistant because of its all aluminum construction. It is rust free and very durable (22 gauge – 0.025″ inch aluminum). The 1/8th inch opening between the louver blades will keep out insects, birds, and animals, thus allowing the air to move through the vent without resistance.

Our Retrofit Roof Vents are designed to fit on an existing base. Replace your old, worn and noisy vent heads! AVP’s all aluminum constructed Retrofit Roof Vents are silent, maintenance free and will not rust! Built to last and will fit on your existing bases. These vents exhaust heat and moisture from attic more efficiently, extending the life of your roof.

Protect your PVC pipes. Used for commercial and residential applications, our PVC Vent Caps are a one piece spun lid made out of rust free aluminum. Great for exhausting gases and vapors. Its durable aluminum make can withstand harsh weather and wind forces of up to 200 mph. We have both static and solar fan varieties that will have a long lasting, clean appearance.

Commercial & Residential Attic Fans

Mechanical Roof Ventilation – Motorized Attic Fans for Plenums & Ducted Ventilation

Our Roof Exhaust Attic Fans are designed for efficiency and energy savings. Our line of Attic Fans exhaust continuously whether the electric motor is on or off. This is due to its vertical louver design, which allows air to exhaust using wind and without moving parts.

Residential Solar Attic Fans

Solar Powered Exhaust Fans – For releasing the summer heat.

Our solar fans use both solar and wind power for maximized energy savings. Our Solar Attic Fans work under direct sunlight to exhaust heat from attic spaces during the summer. They operate very quietly and have a compact design.

Commercial Solar Attic Fans

Solar Powered Ventilation – For Flat Roofs Needing Added Ventilation & Ducted Ventilation.

Our Solar Fans are designed to exhaust hot air whether the fan is on or off because of its inner louver design. Made with rust free aluminum, we have a wide selection of diameters and collar heights to suit your needs. Our solar panels produce Cubic Feet Per Minute (CFM) at angles up to 80 degrees.

Why Install Roof Vents?

What is a roof vent and what is it used for?

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.

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 are (air) intake roof vents?

Air intake vents are used to allow outside air to enter into attics. Intake vents should be located 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:

  • Continuous soffit vents (under the overhang portion of the roof)  original image

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:

Ridge Vents: Ridge vents are installed along the length of a ridge. Below is a picture of a shingle over ridge vent.

Shingle-over ridge vents are covered with shingles to prevent precipitation from entering a building. Because the shingles used over the vent match those used on the roof, shingle-over ridge vents are typically less noticeable than other types of exhaust vents.  original image

Below is a non-shingle ridge vent. Because the exposed exterior material of nonshingle-over ridge vents is different from the adjacent roof covering material, nonshingle-over ridge vents may be more noticeable.  original image

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  original image  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.  original image
