Attic and Roof Ventilation

For your roof to reach its longest live and peak performance your roof and attic need to have a balanced ventilation system.

There are several different products available to ensure your intake and exhaust roof ventilation is balanced. It is important you are aware of your ventilation options for your attic and roof.

Types of Roof Ventilation

Attic ventilation products are categorized as either:

  • Intake ventilation
  • Exhaust ventilation
  • Both intake and exhaust ventilation

Both intake and exhaust ventilation are key parts of your attic and roof ventilation system.

Intake Ventilation

Soffit vents are most common type of intake ventilation. Soffit vents are placed along the length of your house between joists at the eaves. Often when blow in insulation is installed these vents can become blocked, you should request an attic inspection to ensure this is not the case.

Roof mounted intake vents can be used when a home does not have soffits

Exhaust Ventilation

Several types of exhaust ventilation exists, it is important the correct type and enough of it is selected for your home. I would have a local roofing company inspect your home and give you advise on which system to use.

  • Ridge Vents
  • Turtle vents
  • Turbine Vents
  • Powered Roof Vents
  • Gable Vents

Why do I need both intake and exhaust ventilation?

Intake vents are lower on the roof (or in the soffits) and allow exterior air to enter the attic. The air travels up the underside of the roof deck in the attic and exits through the exhaust vents at the top of the roof. Proper attic and roof ventilation helps regulate the temperature of your attic and remove moisture.

Why do I need attic ventilation?

To keep your attic temperature and moisture regulated it is very important you have proper roof ventilation. Without proper ventilation you attic and roof can experience many problems:

  • Mold
  • Mildew
  • Damage to the integrity of your roof
