Common Types of Roofing Vents in Lynchburg Homes

Roof ventilation is an important, and often overlooked, component of a properly functioning roofing system. Roof ventilation systems consist of intake vents and outtake vents, and allow for a consistent airflow throughout the attic and roof that helps hot air escape, instead of becoming trapped underneath the roof. Roof vents come in many shapes and sizes, and not all are created equal. Here are some of the most commonly used roof vents used in Lynchburg homes. 

Box Vents. Box vents are also referred to as “low profile vents” or “flat vents”, are static vents with no moving parts. This type of vent is installed over a hole cut into the roof for vent placement. Box vents create an opening for rising hot air and moisture to escape the attic, and are most effective when installed close to the roof ridge. While box vents are effective, multiple vents within the same roof are often required because one is not effective. 

Power vents. Power vents (mounted on the roof or the gables) are also known as power attic vents (PAVs). These vents have motors that turn large fans that help drive hot air and moisture out of the attic and roofing system. PAVs come in a variety of colors, and some even have thermostats that are able to trigger the fan to turn on when the attic reaches a certain temperature. 

Soffit vents. Soffit vents are intake vents, which are crucial to a roofing system. They allow air to come into the attic and ventilation system. Theyare typically made of PVC or aluminum, and are installed in the soffits (the underside of the overhang of the roof) and the eaves of your roof. 

There are many other types of roofing vents, but these are some of the most common. Depending on the size and shape of your roof, a combination of ventilation styles may be used to achieve adequate ventilation.
