ShingleVent II

 

ShingleVent® II ridge vent installs on the peak of the roof allowing exhaust ventilation all along the roofline -- end-to-end.

ShingleVent II ridge vent has a low profile, shingle-over design that blends in with the roof. Once installed ShingleVent II provides exceptional attic ventilation and is almost invisible from the ground.

 

Description

Functional design and clean lines. For an air of distinction.

 ShingleVent II ridge vent installs on the peak of the roof allowing exhaust ventilation all along the roofline -- end-to-end.

 

This product proves that outstanding beauty and performance can be combined. Design features include an external baffle and internal weather filter for optimum airflow and weather protection. Less than an inch in height, this molded, high-impact copolymer shingle-over ridge vent permits capping of the ridge with shingles like the rest of the roof.

Available with a bag of nails and without nails.

 

ShingleVent II - Shingle-Over Ridge Vent - The Industry Leader - Beautiful Looks and Performance

 

Designed with an external baffle and internal weather filter, ShingleVent II delivers superior attic ventilation and weather protection.


Here’s how it works:

  • ShingleVent IIThe external wind baffle directs airflow up and over the vent, creating an area of low pressure over the vent openings, pulling air out of the attic — even when the wind is not 100% perpendicular to the vent.

  • The external wind baffle also deflects rain and snow over the vent, protecting the roof and attic from weather infiltration.

  • An internal weather filter helps trap fine snow before it can enter the attic, and protects against dust and insect intrusion.

 

 

ShingleVent II Smoke House Demonstration

This video demonstrates the effective ridge vent ventilation of heat and moisture using the Bernoulli Effect.

This demonstration effectively visualizes the wind hitting the external baffle and creating low pressure above the vent openings on both sides of the vent to pull more air through the vent – much more air than thermal buoyancy allows. And, as the wind increases in speed, the vent’s exhaust airflow also increases.

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

300
= Square feet of net free area needed
For example:    
1500 square feet of attic floor space

300
= 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.

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.

“The homeowner bought this house not knowing that the cut-outs for the attic exhaust vents (roof louvers/box vents) were roofed over. The homeowner also did not know that the intake vents were blocked by the insulation inside the attic. Basically, there was zero attic ventilation. We noticed the attic had been treated for mold. When it was time to replace this roof, no other contractors asked to go into the attic before submitting a roofing proposal. We addressed the blocked intake airflow and installed ShingleVent II ridge vent for exhaust.” – Ryan Esquivel, estimator, Keith Green Construction, Inc.

Phone: 214-698-8443
Website: www.arringtonroofing.com

 

“The upstairs air conditioner could not keep the upstairs cool. We were called by the air-conditioning contractor to ventilate the attic. We added rectangular soffit vents, ShingleVent II ridge vent, and The Edge Vent (roof-top intake). We positioned The Edge Vent more than halfway up the roof where the second-floor attic started. The architecture of the house did not allow for The Edge Vent to be installed at the eve of the roof. It had to be installed above the dormers on the front of the house which is close to the floor of the attic. The infrared temperature readings are at 3 PM on 105°F afternoon. ” – Chris Arrington, vice president, Arrington Roofing Company, Inc.

 

Editor’s Note: The attic temperature reading of 114°F on a day with outdoor temps at 105°F is within the recommended summertime range for a properly performing attic ventilation system: within 10-15° of the outside temperature; 20° max. The Edge Vent is designed to be placed at the eave of the roof or moved up the roof 2-3 feet in situations where exposed rafter tails cause the attic to begin up the roof 3 feet or less. In this case, Arrington Roofing has positioned The Edge Vent further up the roof and it’s working. Such applications should be considered on a case-by-case basis and factor in the climate.

“This single-story home had multiple attic exhaust vents existing on the roof: short runs of ridge vent, box vents and a roof-mount power fan. We removed everything and installed continuous ShingleVent II ridge vent (horizontally) along with Hip Ridge Vent (diagonally). The intake ventilation was in good shape with consistent vented soffit around the perimeter of the house.” – Michael Scaperato, Owner, 3rd Generation Home Improvements

 

Editor’s Note: Mixing or combining two different types of attic exhaust vent types as described above can short-circuit the attic ventilation system – cause inefficient airflow and weather infiltration. This is explained in greater detail in an episode of our podcast “Airing it Out with Air Vent.” By exclusively using one type of attic exhaust ventilation, short-circuiting is eliminated.

Rogge Builders, Inc.
Address: 12919 E. Playfield Drive
Crestwood, IL 60445
Phone: 708-388-6576

 

“This roof had several problems. There were multiple types of attic exhaust vents instead of just one exhaust vent system. It had a gable end louver, a box vent, a wind turbine and a roof-mount power fan. Making matters worse, the opening for the soffit vent (intake) was never cut which means it did not have any intake. We did a complete tear off and replacement of the roof deck, installed The Edge Vent (roof top intake) and ShingleVent II ridge vent (exhaust).” – Rich Rogge, Owner, Rogge Builders, Inc.

 

Editor’s Note: Mixing types of attic exhaust vents on the same roof above a common attic short-circuits the airflow (causes inefficient airflow) because one of the types of exhaust becomes the primary source of intake airflow bypassing (short-circuiting) the actual intake vents. Additionally, if the exhaust vents are suddenly acting as intake, they could be bringing in weather, which they are not designed to do. It’s always best to have one type of attic exhaust combined with the necessary intake ventilation low on the roof or in the soffit.

Success Story - ShingleVent II

ShingleVent II ridge vent combines beauty and performance with its low-profile design and proven airflow & weather protection results.

ACI, Hollis, NH
Address: 265 Proctor Hill Road
Hollis, NH 03049


Editor’s Note: Pictured here 7-inch wide ShingleVent II is installed on a metal roof using Country Manor Shake aluminum shingles by Classic Metal Roofing System. ShingleVent II is available in three widths: 7-inch, 9-inch and 12-inch.

 

Important Installation Steps from ACI:

  1. The opening at the peak is the missing plywood sections removed of the asphalt shingles at the ridge only. A single layer of asphalt shingles were left in place over the entire roof and covered with a special underlayment.
  2. Flatten coverable shakes to less than 1/16″ roughness or cover flattened rough shake surface with narrow 1.5″-wide flashing.
  3. Critical to installation is flattened aluminum shake surface roughness preparation and material long-term corrosion/erosion compatibility in conjunction with ventilation. If less than 1/16″ surface roughness is not obtainable, inclusion of approximately 1.5″-wide layer of flat aluminum flashing in between mating surfaces is preferred.
  4. Stainless steel pan head screws were used throughout installation.

SUCCESS STORY - SHINGLEVENT II

Bone Dry Roofing, Inc., Indianapolis, IN
Address: 4825 West 79th Street
Indianapolis, IN 46268
Phone: 317-873-6005
Website: www.bonedryroofing.com

 

Editor’s Note: For this project the homeowner requested a new roof. The shingles were showing significant signs of deterioration. Upon inspection Bone Dry Roofing learned the current pitched roof was built over the top of an existing flat roof. There was zero intake ventilation for either of the two separate existing attics. The existing exhaust ventilation was 4 roof louvers. Bone Dry Roofing proposed ShingleVent II ridge vent for one attic that had a generous ridge length (25 linear feet) and a 30-watt solar powered fan for the 2nd attic (it only had 4 linear feet of ridge length available so a ridge vent would not work). The solar powered fan has a “Solar Controller” that allows fan operation without access to the sun if desired. Edge Vent was used as the intake ventilation.

 

“When we inspected this roof it was clear the shingles were blistering badly and cracking. Lack of proper airflow contributed to this. The customer is very happy with the finished product and is very appreciative that we were able to bring their attic ventilation up to code.” – Judd Haag, General Manager, Bone Dry Roofing

“We had to move The Edge Vent up the roof to access the attic. We separated the attic spaces to reduce the possibility of short-circuiting the system due to vertical height differences. The homeowner has noticed a difference. Even with a small amount of snow on the roof it now melts evenly.”  – Geremiah Gilliand, President, G & G Restoration

 

Editor’s Note: This project in Spring Hill, KS features an 1850s’ built house. G & G Restoration used ShingleVent II ridge vent (exhaust airflow @ horizontal peaks), Hip Ridge Vent (exhaust airflow diagonally) and The Edge Vent (intake airflow).

“We trimmed out the soffit vent with PVC board to reduce the need for maintenance. The overall finished product looks fantastic. The homeowner was really pleased. The temperature and the humidity inside the attic has drastically reduced. A win all around! ”  – Stuart Thompson, Project Manager, Paul Davis Restoration

 

Editor’s Note: Before Paul Davis Restoration got involved in this project the house had 3 roof louvers for attic exhaust airflow and ZERO intake airflow (vented soffit panels were installed but the holes inside the plywood were never cut). Mold growth was observed on the underside of the roof deck and on the rafters. For the fix, and after removing the mold, Paul Davis Restoration installed continuous vented soffit (intake) and a combination of horizontal ShingleVent II ridge vent with diagonal Hip Ridge Vent (exhaust).

“By our estimation, the shingles were less than 10 years old but were already sunbaked due to inadequate attic ventilation. There were only two small intake vents on the underside of the front gable box over the garage. For exhaust, we found the common mistake of two different types being mixed together (roof louvers combined with gable louvers). The homeowner was not interested in having holes cut in the freshly painted soffit for purposes of providing intake ventilation. The solution was to remove the existing exhaust vents, install ShingleVent II ridge vent along with roof-top intake The Edge Vent.”  – Don Chernicky, Makeover Masters

 

Editor’s Note: Makeover Masters originally contacted Air Vent seeking guidance for this project. JSD Sanchez Roofing did the installation. When The Edge Vent is used in a valley the slot stops 12 inches from the valley.

“This house has a lot of hips and valleys with limited horizontal ridges. The limited ridges was a problem for attic ventilation. Using power fans was an option but we presented Hip Ridge Vent to take advantage of the many hips. The homeowners love their decision to go with Hip Ridge Vent instead of the power fans. This house now stands out from the others in the neighborhood. ”  – Jeff Heitzenrater, Vice President of Operations, Triple Peaks Roofing & Construction

 

Editor’s Note: ShingleVent II ridge vent is designed for roof peaks (horizontal). Hip Ridge Vent is designed for the hips of a roof (diagonal).

“This project features ShingleVent II continuous ridge vent with The Edge Vent (roof-top at the eave) intake vents. Can you see them? Low profile, efficient ventilation will help to keep the attic temperature in check all year.” – Mike Lunsford, Owner, Lunsford Construction, Inc.

 

Editor’s Note: : The gable louver visible in the picture has been blocked from inside the attic to avoid possible short-circuiting of the exhaust vents (which can happen when 2 different types of attic exhaust vents are used on the same roof above a common attic).

“For this roof we corrected the existing attic exhaust ventilation and upgraded to ShingleVent II ridge vent. There was a combination of box vents, wind turbines and ridge vent that was not run consistently along the peak of the roof. Now there is exclusively ridge vent and soffit vents for intake airflow.” – Cameron Hurley, Owner, Rampart Roofing & Construction

 

Editor’s Note:  Mixing/combining types of attic exhaust vents (ridge vents, box vents, gable louvers, wind turbines, gable fans and roof-mount power fans) short-circuits the system. This can cause inefficient airflow in the attic and possible weather infiltration (one of the exhaust vents becomes the intake vent and ingests air/weather).

“We replaced all of the ridge vent and cap shingles on this home after replacing the OSB sheathing on both sides of the ridges. We reduced the opening size to Air Vent’s recommended ¾ inches on both sides of the ridge beam, instead of the nearly 4-inch gaps we found under the leaking ridge vents” – Trevor Atwell, Owner, Atwell Exterior Services LLC

 

Editor’s Note:  A wider slot than is required in the Installation Instructions does not increase the vent’s airflow performance.

“This severely damaged roof required a complete tear-off and installation of nearly all new roofing materials and attic ventilation. Along with replacing the damaged wood, adding new shingles and repairing the damaged chimney, we updated the attic ventilation system to include ShingleVent II Ridge Vents.” – Michael Scaperato, Owner, 3rd Generation Home Improvements

 

Editor’s Note:  As you can see from the photos, this created clean, seamless, end-to-end ventilation across the entire roofline of the home.
