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.
