Roof Ventilation: Does Your Home Need It?


Simply put, roof ventilation is an absolute necessity - every home needs proper ventilation! There are quite a few different types of roof and attic vents on the market- the type of ventilation system you use on your roof depends mainly on the climate of the area. Either way, having ventilation integration is an important feature - the main purpose being the regulation of air in attics and, in turn, entire houses.   

There are several different types of vents falling under two main categories: Intake and Exhaust vents. Intake vents allow for fresh, cool air to flow through the attic, pushing out the stale, hot air. The most cost effective and common kind of intake vent is called a soffit vent. Soffit vents are placed under the eaves low on the roof line and allow for cool air to enter the attic. Soffit vents are the first choice for builders if the home style allows for these vents. Other styles of intake vents include: gable vents, drip vents, and over fascia vents. 

Where Intake vents are placed on the bottom of the roof to let cool air flow in, Exhaust vents are located on top of the roof to let hot, humid air escape from the attic. The most common kind of exhaust vent in homes today is a ridge vent. A ridge vent is found at the peak of the roof, and carries down the length of the roof. This allows for the cool air flowing in through the intake vent to push the hot, humid air up and out of the exhaust vent. Other exhaust vents include: static vent, cupola vent, and box vents.

Whichever vents you have, remember, vents need maintenance, too! Sometimes, vents can get clogged by debris. In the event that a vent is clogged, simply blow the vent with a leaf blower or air compressor to clear the way for fresh air to enter the attic.

Without an Intake and Exhaust vent on your roof, you can expect problems in the future. Improper ventilation can lead to moisture damage in your attic and roof, which can lead to ice dams in the winter. Also, keeping temperature moderated during both extreme seasons can help to keep the rest of the home cool as well. Proper ventilation allows for the attic air to stay cooler. When the attic air is cooler, HVAC systems don’t have to work as hard to produce cool air. Finally, a cooler attic leads to a cooler roof, and a cooler roof lives longer - having proper ventilation can help optimize the lifespan of a roof!
