Purpose of Ventilation

Your roof is constantly exposed to the elements including stormy weather, ultraviolet rays, and falling debris. Being the first line of defense for your home and protection, it's important to make sure your roof is functioning properly, which means it needs to be ventilated appropriately. When the roof gets too hot it can hold on to moisture causing both roof and attic damage as well as retaining heat and increasing cooling costs. The level of ventilation in a roof is directly correlated to the lifespan of the roof, and proper ventilation will increase the lifespan and minimize roofing issues. A roof that is properly ventilated will add years of life to your roof, drastically lower cooling costs, and keep your home safe and comfortable.

Roof Ventilation Methods

Depending on the particular needs of your building and structure of your roof, there are two important aspects of roof ventilation: intake and exhaust. Both act as a facilitator to direct hot air out of the attic and cool air into the attic to keep the temperature in the attic consistent. They both also come in powered forms which utilize the same concepts, but use a power source. Powered roof vents are helpful in areas that have very little wind.


Intake vents allow cool, fresh air to enter the attic space. Because hot air rises, the cooler air comes in beneath the stagnant warm air, to push it up and out of the attic. Types of intake vents include:

  • Individual Soffit Vents
  • Continuous Soffit Vents
  • Eave and Drip Edge Vents


Exhaust vents are meant to release stale, hot air out of the attic. Because of this they are located on higher areas of the vent. Examples of exhaust vents are:

  • Ridge Vents
  • Static Vents
  • Gable-end Vents

Each roof and attic will have different and very specific needs for optimal ventilation.
