The Importance of Attic Ventilation / Ridge Vents

Whats A Ridge Vent?

A ridge vent is an air exhaust vent that is positioned on the roof's peak. To install this vent, an air slit is first carved in the roof deck near the top of the roof. The ridge vent itself then covers this air gap.They are intended to resist wind-driven rain and snow, as well as bug and debris infiltration, and aid to provide continuous, consistent exhaust ventilation at the highest section of the attic.With the exception of metal ridge vents, which do not require the installation of ridge cap tiles, ridge cap shingles are generally put over the ridge vent to protect it and create a clean completed look on the roof.For the attic ventilation system to function correctly, air must be able to enter and depart the attic in order to provide a constant flow of outside air through the attic area. Cooler, dry air will reach the lower attic level through eave and soffit vents, which are located where a roof or overhang juts out over the home's external wall.

When are they Needed?

Many homes are excellent candidates for ridge vents, depending on the amount of exhaust ventilation required for the attic space and the physical roof shape. Homes with a lot of ridge line, for example, are frequently adequately ventilated using ridge vents.If your attic is completed or the air in the area is conditioned, a mechanical means of expelling heat and moisture may be required. You should speak with a design specialist or an HVAC contractor to ensure that your system is large enough to provide the airflow required to keep your attic cool.
