What kind of roof vents are available for my home?
Box vents also called low profile vents, louvers, flat vents, turtle vents, or static vents. This means they have no moving parts. The vent is installed over a hole cut out of the roof. They create an opening for the rising hot air and moisture to escape through.
Wind-driven turbine vents work much like box vents, except that when the wind is blowing, they move more air than box vents. The spinning action, triggered by wind, draws hot air and moisture up out of the attic.
Power ventilators have motors that turn fans to pull hot air and moisture out of the attic. Some come equipped with adjustable thermostats and/or humidistats which come on when the attic reaches a certain temperature.
Ridge vents have no moving parts and as indicated by their name, are installed on the ridge of the roof. A ridge vent should run the entire length of the roof’s horizontal ridge, blending into the roofline for a more attractive home. Ridge vents combined with under eave venting (soffit) is the most efficient system you can install.
Soffit Vents provide a means of air intake into the roof’s ventilation system. They are installed in soffits and eaves and are most effective when used in conjunction with a continuous ridge vent.
Many times when you see Cupola vents, they are for decoration and serve no true purpose. However, they can be functioning static roof vents. They sit atop a high ridge and frame an opening in the roof system, allowing hot air and moisture to rise and escape the building. They are limited in their abilities and usually fill a support role to another roof vent system.
