How roof turbine vents work.

Whirlybird roof turbine vents are as easy to install as turtle vents and are one of the most popular ways remove hot air out of the attic space. 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. Continuous soffit vent and a ridge vent beats a turbine vent any day. The last thing you want to do is stuff insulation in the vents.

Intake vents located at the lowest part of the roof under the eaves allow cool. 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. 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.

This convection movement naturally draws in cooler outside air to replace the air that just exited. A turbine vent is a passive ventilation device. Dependable construction has made a video on how to replace a turtle vent on a roof. Well now you know.

And in fact just so you know those spinning roof vents are probably not the best way to vent your roof. The popular ridge and soffit ventilation systems. The intake should be installed at the soffits or blocking where the walls meet the roof. Somebody told me well you ll save money in the winter if you cover your turbines up tom.

The conventional wisdom is to put in soffit vents down at the bottom of the roof so the replacement air can enter here and flow up under all the roof sheathing. A ridge vent runs across the top of the roof s peak. Wind driven turbine vent wind driven roof vents will pull more air from the attic but only when the wind is blowing. A turbine has a series of vanes that spin as wind passes through them.

Attic ventilation works on the principle that heated air naturally rises primarily utilizing two types of vents. All things being equal wind driven turbine vents also known as a whirlybird roof vent do move more air than flat vents but only when the wind blows. Roof turbine vent tips turbines work for free. Ventilating attic spaces in winter.

Since turbines are attached directly to attic spaces they can siphon away that moist air effectively. To take full advantage of this effect a roofer will generally install intake roof vents for houses lower on the roof closer to the eaves while placing exhaust vents higher near the peak to let the cold air push the hot air out more easily.
