Box vents square covered vents with no moving parts.
Ridge roof vents versus other vents.
Ridge vents long exhaust vents that are installed at the peak or ridge of the roof.
Like other vents ridge vents need eve vents to work properly.
If you don t know how your roof vents work or if you re unsure about your attic ventilation in general you should talk to a roof inspector about your current system and any inherent weaknesses that may be at.
Unlike turbines this venting style does not have any moving parts.
Ridge vents roof with ridge attic vents.
It is best to use a continuous ridge vent on a shingled roof.
Ridge vents are located along the whole peak of your roofline and are covered with screening.
Ventilation of energy efficient houses.
Ridge vent versus roof vent.
Wind turbine vents metal vents with an internal turbine that helps circulate air as the wind blows.
A ridge vent installed along a roof s peak will move hot and humid air up and out of the attic.
It has the ability to work with vaulted ceilings and you only need one of them to get the job done for ventilation as compared to multiple box vents.
Roof ridge vents and other forms of roofing ventilation work better when homes are in colder climates.
The general rule of thumb is that the colder the climate the more your attic benefits from the use of ventilation.
This balanced system provides greater airflow than any other fixed vent and it s the most attractive system.
Continuous ridge vents are more expensive than roof box vents but since they are non mechanical there is no need for electric connections or concerns that there could be an electrical failure.
Rather just have the ridge vents and the soffit vents paired together.
This is different from soffit vents which allow air to travel into the attic.
This is a passive ventilation system relying on the air pressure from inside your attic to release the warm air.
Most effective ventilation uses a ridge and soffit continuous ventilation system but even these designs can vary from roof to roof.
It also works better because it creates a vacuum.
This will mean that you will need to cover or remove the gable vents though as this will hinder the effectiveness of the ridge vent.
A ridge vent is similar to a screen and allows heat to escape up and out of the attic.
I would recommend you cover or remove any existing roof vents if you are planning to install ridge vents.
Ridge vents are a passive system simply allowing hot air to rise up through them rather than pushing it out as a fan does.
This option can still reduce your hot air during the summer months in a warm climate but there are cheaper and more.
Years of research have proven that air vent ridge vents combined with under eave venting are the most efficient and effective system you can install.
Power vents vents with a powered turbine that needs to be connected by an electrician.
