Types Of Roof Ventilation Systems

It uses the process of natural convection so that hot air and moisture can escape into the surrounding air.

Types of roof ventilation systems.

Comprised of intake and exhaust vents the basic roof ventilation system can be found in a few forms including turbine vents low profile vents and ridge vents that are specially designed to accommodate specific roof shapes. Other names for this type include low profile flat or turtle vent. Effective attic ventilation systems reduce damaging heat and moisture in your attic promote energy efficiency by helping to reduce the load on your air conditioner in the summer and also reduce the risk of ice dam formation on your roof. The two roof ventilation options intake vents and exhaust vents should be placed to take advantage of the natural increased speed of air circulation.

Attic ventilation works on the principle that heated air naturally rises primarily utilizing two types of vents. Intake vents such as soffits are placed lower on the roof usually under the eaves. See the benefits of attic ventilation a new roof is more than just shingles. Has provided a great online educational tool for understanding the difference between ridge vents power vents and static vents.

The box vent is also known as a static vent because it has no moving parts. Exhaust vents unlike intake vents are installed at the topmost point of the roof. Solar powered vents gable mounted vents louvers rotating turbine roof vents and more. Intake vents located at the lowest part of the roof under the eaves allow cool.

Moving vents have the benefits of actively removing hot air and moisture from your roof but you will have to rely on wind power to operate these roof vents. These vents are available in various types and styles and soffits are easy to install under the roof s overhang which is known as the soffit. The downside to turbine vents is that they don t provide much venting power on calm days. They are meant to let the air from indoors travel outdoors so there is continuous air flow.

Energy saving solar powered vents and skylights are also available. What type of ventilation system is right for you. Turbine vents are not low profile but in windy climates they provide more ventilation than other types of roof vents. The trapped hot air goes out from the attics through the ventilation space into nature.

On a windy day the vent s turbine mechanism spins which moves hot attic air up and out. The most common type of moving roof vent is the wind turbine. This occurs through the rising of warm air and the falling of cooler air.
