Intake vents located at the lowest part of the roof under the eaves allow cool.
Types of roof ventilation systems.
See the benefits of attic ventilation a new roof is more than just shingles.
Attic ventilation works on the principle that heated air naturally rises primarily utilizing two types of vents.
Solar powered vents gable mounted vents louvers rotating turbine roof vents and more.
It uses the process of natural convection so that hot air and moisture can escape into the surrounding air.
Instead the box vent is installed over a hole cut out of the roof.
Ridge ventilation is suitable for peaked roof systems.
The two roof ventilation options intake vents and exhaust vents should be placed to take advantage of the natural increased speed of air circulation.
This occurs through the rising of warm air and the falling of cooler air.
Intake vents such as soffits are placed lower on the roof usually under the eaves.
Types of roof vents continuous individual soffits soffit vents are made of aluminum or vinyl and are one of the most popular intake vents.
On a windy day the vent s turbine mechanism spins which moves hot attic air up and out.
The box vent is also known as a static vent because it has no moving parts.
Has provided a great online educational tool for understanding the difference between ridge vents power vents and static vents.
Exhaust vents unlike intake vents are installed at the topmost point of the roof.
What type of ventilation system is right for you.
Other names for this type include low profile flat or turtle vent.
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.
Energy saving solar powered vents and skylights are also available.
The most common type of moving roof vent is the wind turbine.
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 trapped hot air goes out from the attics through the ventilation space into nature.
The downside to turbine vents is that they don t provide much venting power on calm days.
Turbine vents are not low profile but in windy climates they provide more ventilation than other types of roof vents.
