create a clean, unclutterd roofline.
The low-profile, shingle-over look of VenturiVent Plus creates a clean, uncluttered roofline. It installs on the peak of the roof, allowing exhaust ventilation along the entire ridge -- end-to-end. With a 12" width, matching shingles can be installed over the vent, allowing the vent to appear almost invisible from the ground.
VenturiVent Plus features an external baffle that maximizes airflow performance and helps protect the attic from weather infiltration. It’s also designed for easy installation. Factor in the aesthetic advantages of a low-profile ridge vent and it’s easy to see why VenturiVent Plus is the vent of choice by roofing professionals
Includes a bag of nails.
The low-profile, shingle-over look of VenturiVent Plus creates a clean, uncluttered roofline; and the vent performs better than other types of exhaust vents which are a lot more noticeable on the roof.
- Exceptional airflow. An external baffle creates low pressure over the vent openings to "pull" air from the attic. VenturiVent Plus provides 18 square inches of net free area per linear foot.
- Advanced weather protection. The external baffle deflects wind and weather over the vent to help protect the attic from rain and snow infiltration.
- Easy Installation. VenturiVent Plus has pre-printed slot guides for truss or ridge pole construction. Pre-drilled nailing holes are designed to assure proper nailing. The vent is pre-formed to a 4/12 pitch, and fits pitches from 3/12 to 16/12.
- Limited Lifetime Warranty and 5-year Replacement Plus™ Protection. Provides peace of mind for the homeowner and installer.
- Includes nails. VenturiVent Plus with nails has 30 3-inch ring shank, galvanized roofing nails bagged and taped to each 4-foot piece inside the carton. Installers will not have to hassle with removing nails that are snapped along the side of the vent prior to fastening.
When installed properly, all Air Vent products mentioned here comply with the net free area requirements of nationally recognized model codes, including those written by the International Code Council. In addition, the vents have product evaluation approvals from Dade County, Florida, ICC and TDI.

THE SIMPLE MATHEMATICS OF A BALANCED RIDGE VENTILATION SYSTEM
- According to most building codes, you need 1 square foot of ventilation for every 150 square feet of attic floor space.
- For new home construction that includes a vapor retarder, the minimum is 1 square foot of ventilation for every 300 square feet of attic floor space.
- If your vents are split between ridge vents and intake vents, the minimum requirement is also 1 square foot of ventilation for every 300 square feet of attic floor space.
To determine how many feet of net free area you need, use this formula:
|Square feet of attic floor space
|=||Square feet of net free area needed|
|1500 square feet of attic floor space
|=||5 square feet of free are a needed|
- To determine how many feet of ShingleVent® II, Multi-Pitch FilterVent® or VenturiVent Plus™ you need, use this formula:
- 1/2 net free area x 144 ÷ 18 = feet of ridge vent needed
- For example: 2.5 (based on net free area of 5 square feet) x 144 ÷ 18 = 20 feet of ridge vent needed
- To determine how many feet of Air Vent soffit vents you need, use this formula:
- 1/2 net free area x 144 ÷ 9 = feet of soffit vent needed
- For example: 2.5 (based on net free area of 5 square feet) x 144 ÷ 9 = 40 feet of soffit vent needed
- The following charts may be used to:
- 1. Determine how much net free area is needed to satisfy FHA requirements.
- 2. Balance your ridge vent system.
DETERMINING VENTILATION REQUIREMENTS
|Min. Net Free Area Required
(if balanced between intake and exhaust)
Note: ShingleVent II and Multi-Pitch FilterVent provide 18" of net free area per linear foot.
INSTALLING A BALANCED RIDGE VENT SYSTEM
- Measure the square footage of the attic (length x width).
- Measure the length of the ridge.
- Refer to the chart above for required net free area and minimum length of ridge for attic square footage.
- Note: In most cases, the length of the ridge balanced with the same net free area of intake vents will satisfy FHA minimum standards and most building codes.
- Use the chart below to calculate the amount of intake vents that should be installed to balance your ridge vent system.
- Always install ridge vents from end to end across the entire ridge for best appearance and to provide maximum ventilation area.
- Hip roofs, dormers and T- or L-shaped roofs may require a specially designed ventilation system. For information, request a copy of Air Vent's Principles of Attic Ventilation.See Contact Us.

Success Story - VenturiVent Plus (with help from the Air Vent App)
Address: 13316 Millard Avenue
Omaha, NE 68137
Phone: Office: 402-896-3639; Cell: 402-681-2180
“The homeowner asked us for a bid for a roof replacement due to damage from a hail storm. While walking the perimeter of the house, my salesman noticed that there were only a few soffit vents installed and they were only on one side of the house. This prompted him to open the Air Vent app and calculate how much intake and exhaust that a house/attic of this size should have. The existing roof had roughly 60 ft. of ridge length available and a rolled ridge vent installed. My salesman determined this house would actually require a ridge vent that had increased airflow (that is, more Net Free Area per linear foot) instead of the rolled ridge vent due to the length of ridge present.
He also found that the home needed an additional 13 16” x 8” rectangular undereave vents to balance the intake with the exhaust. Finally, upon removing one of the existing intake vents, he found that the insulation was sandwiched between the roof deck and the exterior wall of the house that extended up into the soffit area. Essentially, this house had no intake at all. We fixed the issues by cutting in the additional undereave vents, adding attic insulation baffles in most of the rafter bays, and installing Venturi Vent plus ridge vent. The homeowner has a beautiful new roof that ventilates properly for the first time ever. ” – Brett Huizenga, Owner, Hometown Roofing, Omaha, NE
Editor’s Note: The Air Vent app is a quick, easy way to confirm if the attic has a balanced amount of intake and exhaust vents based on the attic’s square footage (length x width, floor of the attic). If you do not know the actual attic square footage, an acceptable Plan B measurement is the footprint of the house. The app is available free for both IOS and Android devices.

A real-time demonstration of the difference between a balanced attic ventilation system and unbalanced. This is exactly why intake airflow is so critical. And see for yourself the Bernoulli Effect when the wind hits the external baffle on ShingleVent II ridge vent. Wow!
