Ft of vent space half dedicated for air intake in the soffits and the other half for exhaust on the roof.
How roof turbine vents work.
The turbines are adjustable so that the spinning part is level even though the roof is slanted.
One static vent style is the turbine vent.
It s the exact same process for a roof turbine vent.
Turbine vents use a combination of wind and convection to extract stale hot air from inside your home and replace it with the cool clean air from the outside.
Good attic ventilation is important for preventing ice dams in the winter.
The base flashing of the turbine vent is identical to the bath fan flashing you ll see.
Since turbines are attached directly to attic spaces they can siphon away that moist air effectively.
These all work well and are typically installed near the top or the peak of the roof called the ridge.
A ridge vent runs across the top of the roof s peak.
These can be ridge vents wind turbines or the flat vents your roofer wants to install.
This is most effective in areas where winds average at least five miles per hour or otherwise will not offer the most effective reliable source of venting.
To get the best performance these vents should be within three feet from the ridge.
Homeowners can choose from a variety of shapes and colors that closely match their shingles so that the vents won t appear too out of place on the roof.
How to install turbine vents.
The installation of a turbine vent is nearly identical to a static vent.
Attic must have 5 sq.
Roof vents need to move hot humid air from the attic to the outdoors so that humidity doesn t build up and cause mold rot or other moisture problems that findlay roofing regularly sees when dealing with attic issues.
A turbine is installed directly on the top of a roof and uses wind power to suck hot and humid air out of the attic.
Most residential homes have some type of attic ventilation.
Ventsure 4 foot strip heat moisture ridge vent.
These will not rust.
How do turbine roof vents work.
A turbine vent draws air from inside the attic as wind turns the turbines.
It could be dormers gable end vents ridge vents turtle vents or turbines vents.
In addition pay attention to the maximum roof pitch that will work with the turbines.
Not all turbines will fit all roof pitches.
27 lineal feet required.
Nothing about the install is different.
Unlike turbines this venting style does not have any moving parts.
Because warm air rises up the wind powered vents with their spinning action tend to suck the air outside.
Choose one of the following products to meet the recommended exhaust nfva of 528 square inches.
If your roof is not too steep and you have asphalt shingles this is a diy project.
A turbine has a series of vanes that spin as wind passes through them.
