Roof Ventilation

A healthy roofing system starts with a well-ventilated attic

Proper ventilation can help prevent damage and premature aging caused by moisture in the winter and excess heat in the summer. It will:

  • Help allow outside air to flow naturally upward and out of attic
  • Promote a cool, dry attic
  • Help prevent moisture from becoming trapped in insulation, structural wood, shingles and roof deck
  • Help prevent rotting, mildew, drywall damage, peeling paint and warped siding
  • Provide year-round performance for consistent ventilation without energy consumption.

In order to create a consistent flow of cool, dry air through your attic, you need to make sure the air has a way to come in and go out: intake and exhaust. For a roof, intake is usually achieved through eave and soffit vents, while exhaust is achieved through vents in the gables, deck or ridge. It’s important there is a balance between the intake and exhaust ventilation to help ensure air flows smoothly and efficiently.

Without proper ventilation, everyday household activities can wreak havoc on a roofing system:

  • In the summer, heat buildup in the attic can encourage premature aging and cracking in wood and other roofing materials. Unwanted heat can also transfer into living areas, making it uncomfortable and reducing energy efficiency
  • In cold weather, warm air generated by activities such as laundry, showers, dish washing and cooking can cause moisture buildup in the attic

Combat these issues with a roofing system that offers balanced ventilation and uses the appropriate amount of attic insulation to enhance shingle performance. The VentSure® Balanced Air Ventilation System features a variety of intake and exhaust solutions as well as active and passive ventilation options.


Roof Ventilation

VentSure® InFlow® Vent

Properly ventilating your attic is one of the best ways to increase the longevity and performance of your roof. As part of a VentSure® Balanced Air Ventilation System of intake and exhaust, the VentSure® InFlow® Vent helps reduce heat and moisture buildup that can lead to ice damming and roof deterioration.


Roof Ventilation

VentSure® 4-Foot Strip Heat & Moisture Ridge Vents with Weather PROtector® Moisture Barrier Offer Exceptional Weather Protection

VentSure® 4-Foot Strip Heat & Moisture Ridge Vents work with VentSure® intake vents and/or VentSure® InFlow® intake vents to help improve air flow through the attic. They are flexible enough to conform to virtually any roof slope and have a unique baffle design and Weather PROtector® moisture barrier to help provide outstanding performance.


Roof Ventilation

VentSure® 4-Foot Strip Heat & Moisture Ridge Vents

VentSure® 4-Foot Strip Heat & Moisture Ridge Vents work with VentSure® InFlow™ intake vents and/or undereave soffit vents to help improve air flow through the attic. They are flexible enough to conform to virtually any roof slope, and their unique baffle design improves airflow by keeping leaves, pine needles or similar debris from impacting the performance of the vent.


Roof Ventilation

VentSure® Rigid Roll Ridge Vents

For an efficient roofing system, it’s essential that the attic stay dry and cool. VentSure® Rigid Roll Ridge Vents are a Weather PROtector® Moisture Barrier membrane that protects against weather infiltration. They have a low profile and use a shingle-over construction for durability and protection.


Roof Ventilation

VentSure® Solar Exhaust Fan

Proper attic ventilation, a balanced system of both intake and exhaust, is critical to the performance of a roofing system. The VentSure® Solar Attic Exhaust Fan is designed to work as an integral part of a VentSure® Balanced Air Ventilation System by using solar power to actively exhaust air from your attic. In the summer, the heat and humidity can lead to mold, mildew, premature deterioration and higher energy bills. In the winter, the warm air in the attic can cause snow to melt and refreeze at the eaves where it can prevent water from reaching the gutter – a problem known as ice damming, which can potentially cause water back-up and leaks. The VentSure® Solar Attic Exhaust Fan helps keep your house properly ventilated using solar power, making your home comfortable while helping to protect your roof.

Roof Ventilation

Raft-R-Mate® Attic Rafter Vents

An attic with balanced ventilation has undereave or soffit vents, which allow fresh air into the attic. The fresh air flows up between rafters to the ridge, where a ridge vent, roof vents or gable vents allow the air to exit. If insulation is allowed to bunch against the inside slope of the roof between the rafters, air will be blocked before it can traverse the attic. Raft-R-Mate® Attic Rafter Vents create a space between each rafter for air to flow freely up the rafters and into the attic.
