One of the leading causes of attic ventilation problems is insufficient or incorrectly installed intake ventilation. To work efficiently an attic ventilation system must be balanced with intake and exhaust vents.

Air Vent, the leading manufacturer of residential attic and foundation ventilation products, has recognized this fact for years after extensive laboratory and field testing. Unfortunately, intake is often overlooked. Perhaps it’s because the roof design makes installing intake vents impractical (no overhang). Maybe it’s because the contractor doesn’t want to hassle working overhead cutting into the soffit/eaves.

That’s the beauty of The Edge™ Vent. It’s a shingle-over, rooftop installed intake vent that keeps the roofing contractor on the roof and it can be used on any home with or without overhangs.

Since its debut in 2008, The Edge Vent has helped contractors solve a variety of intake ventilation problems. Here are a few examples.

Winning the Ice Dam Battle

Strander Roofing & Seamless Gutters in Lodi, Wis., combined proper insulation and a balanced attic ventilation system - including The Edge Vent - to finally solve the annual ice dam headache for a customer. “This home had huge ice dam problems due to poor ventilation and their heat bills were virtually through the roof,” said Chad Strander, owner of the company. “The home was a Cape Cod style structure so we cut The Edge Vent along the bottom edge for intake and ShingleVent® II on the ridge for exhaust.” Strander Roofing installed two layers of 3-inch insulation (R-Value 42) and applied fir strips over the top of the insulation; then installed the sheeting to the fir strips. “The homeowner was quite excited for the first winter without ice dam problems,” Strander said.

Improving Interior Comfort

It’s no mystery a two-story house with individual roof louvers for exhaust and nothing for intake is not receiving the benefits of a balanced attic ventilation system. Enter Elite Exteriors in Burnsville, Minn.

“This house did not have an overhang and thus there were no intake vents. We added The Edge Vent for proper intake and replaced the roof louvers with continuous ShingleVent II ridge vents,” said Jason Vogen, CEO of Elite. “The homeowner has seen a drastic improvement in the air temperature in the upper level of his home; which ultimately will increase the longevity of the roof and the life of his home.”

Goodbye to Working Overhead With Soffits

Performance aside, Tom Galgerud, president of Monarch Siding & Windows, Inc. in Papillion, Neb., likes the ease of installation, which will simplify the process of making sure proper intake ventilation is part of each job.

“The Edge Vent is very easy to use and adds so much intake airflow without worrying about the existing soffit vents,” Galgerud said. “Thanks to The Edge Vent I am able to educate homeowners about their roofing problems and find a suitable solution.”

Suitable for All Climates

Air Vent engineers designed The Edge Vent to be used with confidence in all climates. Patented internal baffles and drainage system along with an internal weather filter provide three levels of weather protection. Each 4-foot piece has an integrated end plug on both ends to provide a finished appearance and weather protection. It can be used on roofs with minimum 3/12 pitch. Its 9 square inches of Net Free Area per linear foot are perfectly balanced with ShingleVent II ridge vent. For more information, visit www.airvent.com.
