Welcome to another issue of e-Vent Newsletter. This marks the start of our 3rd year publishing this. It all started at the request of you asking for additional resources beyond our annual Ask the Expert™ seminars each winter. Speaking of our seminars, like you, we adjusted as best we could during the COVID-19 pandemic and transitioned from in-person venues to virtual seminars via Microsoft Teams. You’ll find a story about it inside. We are committed to continue sharing industry news, tips you can use in the field, advice for challenging attic ventilation projects, and noteworthy Air Vent happenings. We’ll continue to publish twice a year, midway and year-end. Email us your comments here: firstname.lastname@example.org.
Thank you! Stay well out there. - Paul Scelsi, Ask the Expert™ Seminar Leader
DID YOU KNOW?
Shingle Life is Cut Short 24% Due to Improper Attic Ventilation
We polled residential roofing professionals across North America and asked: “In your local field experience, what percentage of shingle life reduction do you see due to incorrect or zero attic ventilation?” The results came back @ 24%. We dug a little deeper and found the following shingle damage revealed: extreme to complete granule loss, blistering on the shingles, shingles curling up on the end, brittle shingles, premature dry-out, and cracking & fracturing throughout the shingle. You can read the first-hand accounts from the roofing contractors themselves in Roofing Contractor magazine: Improper Attic Ventilation Reduces Shingle Life 24%.
ShingleVent® II Ridge Vent: Proven Performance. Beautiful Appearance.
ShingleVent II four-foot plastic ridge vent is our flagship product for two reasons. It delivers proven performance while giving the roof curbside appeal .
Proven Performance: When the wind – as slight as a gentle breeze – hits the vent’s external wind baffle it directs airflow up and over the vent, creating an area of low pressure over the vent openings. This low pressure pulls air out of the attic, even when the wind is not 100% perpendicular to the vent. It’s called the Bernoulli Effect and it’s exactly what gives lift to an airplane. Check out the Bernoulli Effect in action: ShingleVent II Smoke House Video and ShingleVent II Smoke Candle Video.
Additionally the external wind baffle is the first line of defense to deflect rain and snow over the vent, protecting the roof and attic from weather infiltration. See it for yourself: ShingleVent II Water Infiltration Test.
Ridge vents like ShingleVent II are the only type of vents installed continuously along the peak of the roof to provide non-stop exhaust airflow for the attic. No other category can deliver that.
With its low-profile design and matching shingles installed on top, ShingleVent II blends in beautifully with the roof. The two house photos featured with this story showcase this courtesy of Edgar Arellano, Lifetime Roofing, North Salt Lake, UT.

New website page helps with insurance claims
We bundled multiple resources on one page of our website to help roofing contractors and homeowners when working with insurance companies as part of a storm-damaged roof replacement claim. The goal is to provide enough information, so insurance agrees to pay to either bring the attic ventilation up to current code standards or improve it to a better system.
Here are just some of the many 3rd-party resources you’ll find pointing to the benefits of proper attic ventilation – which is a balanced system of both intake vents and exhaust vents:
✓ ARMA: The Asphalt Roofing Manufacturers Association (shingle manufacturers)
✓ APA: The Engineered Wood Association (plywood and OSB roof sheathing manufacturers)
✓ Building Code
There’s also the homeowner’s insurance policy and the full terms of the shingle warranty to double-check as well. Here’s the link to the page: Resources to Help with Insurance Claims.
Please listen to our podcast on the topic featuring our 1-on-1 interview with Kyle Pyatt, Gen 3 Roofing Corporation, Centennial, CO. Pyatt says 95% of the roofs Gen 3 works on are insurance claims. Listen to the podcast episode here: Getting Insurance to Pay for Attic Ventilation.
Question: “Is there anything to be concerned about as far as adding a whole house fan after having a ridge vent installed?”
Answer: There is nothing to be concerned about when installing whole house fans after installing a ridge vent. Whole house fans work in harmony with the attic ventilation system, which ridge vents are part of. When the whole house fan is running it actually overpowers the attic ventilation system and turns every vent inside the attic into “exhaust outlets” – both the intake vents and the exhaust vents. For example, the rectangular undereave vents in the soffit and the ridge vent at the peak would all become “exhaust” for the running whole house fan. All of the vents are letting the air out of the attic that the whole house fan brings into the attic. In the illustration with this story, the attic exhaust vents shown are gable louvers. Other exhaust vent options include wind turbines, ridge vents and box vents. Make note that the intake vents are in play, too.
Whole house fans are used in climates where air conditioning is not needed to cool the house or in climates where you can give the air conditioner a break by opening the windows in early morning and evening hours. Whole house fans are installed in the ceiling of a central hallway in the house connected to the attic. Homeowners open windows in the house and turn on the whole house fan. The fan brings in the cooler outside air and circulates it throughout the house. The hot, stale air is pulled into the attic where it eventually exits through the attic intake and exhaust vents.
What you should please double check is that the attic is properly balanced with intake and exhaust vents for the size of the attic. That will all but guarantee that the whole house fan has enough “exhaust outlets.” Also, make sure the whole house fan has been sized correctly for the living space. You do not want a whole house fan struggling to find enough “exhaust outlets” because the attic ventilation is either incorrectly sized for the attic or the whole house fan itself is oversized for the living space.

FOUND IN THE FIELD
Contractor: Shawn Bellis, Epic Exteriors, Overland Park, KS
The Issue: Bathroom Fan Ductwork Terminates into the Attic Dumping Excessive Moisture
Solution: Run the Ductwork Through the Roof to a Dedicated Bathroom Vent
In the photographs below the ductwork for the bathroom fans terminates inside the attic. This allows excessive moisture to dump directly into the attic where it can potentially condense in the colder months of the year. If it condenses, it could wet the attic insulation – reducing its effectiveness – wet the wood members inside the attic, and potentially the ceilings in the living space below. That could lead to mold, wood rot, and poor indoor air quality. The ductwork should go through the roof vertically or out to the side gable wall of the attic into a bath fan outlet vent designed with a damper.
Have a Field Find you want to share? We love photos from the field. They are a popular feature weekly on our Facebook page and in our Ask the Expert™ seminars. We’ll take your success stories, handy tips and mistakes to avoid please. Send them to Paul Scelsi firstname.lastname@example.org. Thanks for sharing.

IN THE NEWS …
Roofing professionals across North America helped Air Vent write helpful articles sharing best practices, solutions, and mistakes to avoid. Here are the most recent that appeared in industry publications. THANK YOU!
A game changer for this category of ridge vent
Roofing contractors, builders and remodelers who currently install standard mesh rolled ridge vents will notice RidgeHawk’s differences immediately – Air Vent’s new ridge vent. The highlights:
