Roof turbine does not turn.

While a turbine looks a little complex at first glance it s actually very simple. If the wind is blowing and catches the fins then the turbines act like giant vacuum pumps sucking hundreds of cubic feet of hot air out of an attic per minute. Rafter vents or insulation baffles install in any rafter space to create narrow gaps that direct fresh air from the soffit vents to the peak of the roof. This is a standard turbine vent.

Examine the turbine from the exterior from the roof. I have 2 whirley bird turbins. The turbins do not turn much at all. A turbine may fail to spin if the bearings become rusty or obstructions such as ice leaves or twigs have become wedged into the turbine.

Not all turbines will fit all roof pitches. 2 of my 3 turbine vents on my roof won t turn unless there s a stronger wind. The faster the wind speed the faster the turbine rotates. Much like a window this round vent is powered by the wind.

The wind has to blow pretty hard for them to turn good. Normally the force of even slight breezes will cause the turbine vent to spin. In addition pay attention to the maximum roof pitch that will work with the turbines. As it spins the air blown from the vent is strong enough to blow rain away from the openings between the fins.

Step 3 clear any obstructions away from the turbines by pulling them free. The turbines are adjustable so that the spinning part is level even though the roof is slanted. These specialty vents do not affect the. When the wind blows the right way it turns the fan which in turn draws up air from the attic and disperses it.

Turbine fans have no power other than wind so when the wind is not blowing the turbine does not turn. Every turbin in my neighborhood is turning and mine may slowely turn. All under one attic. Do i have a low pressure system.

These will not rust. And my electric bill is outrageous with the ac running almost non stop. Just hot air rising out of one will make it spin. Also barely using my finger of course they spin freely no noise etc.

It houses a circular fan that s very sensitive to breezes. I ve gone on the roof and white lithium greased both and but a level on them and they are pretty close to level.
