Roof Ventilation

Roof ventilation system

One of the things we have learned as our estimators have gone out and talked to our customers is that many of our customers know little and are interested in learning more about roof ventilation and what types work best. Ideal ventilation is as the hot air leaves or diminishes, cool air moves in to replace it, creating a balance. If you do not have good roof ventilation you may run into the following problems: decreased life of your shingles, ruined attic insulation, damage to the roofs framing components and possible mold growth. The two main components of roof ventilation are the intake vents and the exhaust vents.

Intake Vents for roof ventilation

Intake vents are installed along the roofs lowest eave at or near soffits or eaves. Intake vents are installed to let outside air move freely into the attic and ventilation space. Intake vents are designed and installed to prevent precipitation, animals and insects into the attic and ventilation space. When an intake vent is installed it is very important to ensure that the air flow is not blocked by other materials such as attic insulation. The most commonly used intake vents are continuous soffit vents, individual soffit vents and drip edge or eave vents.

Exhaust Vents

Exhaust vents are installed near the roofs ridge or highest point taking advantage of natural convection. Exhaust vents allow the air in the attic and ventilation space to exit to the exterior of the house to make space for the fresh air to come in from the intake vent. Exhaust vents are also made to prevent precipitation, animals and insects into the attic and ventilation space. There are several types of exhaust vents.
