Roof Turbine Does Not Turn

In addition pay attention to the maximum roof pitch that will work with the turbines.

Roof turbine does not turn.

Walking around my soffits yes i do have soffit vents and from the attic i can see sunlight in. 2 of my 3 turbine vents on my roof won t turn unless there s a stronger wind. When the wind blows the right way it turns the fan which in turn draws up air from the attic and disperses it. Examine the turbine from the exterior from the roof.

While a turbine looks a little complex at first glance it s actually very simple. These will not rust. All under one attic. Just hot air rising out of one will make it spin.

And my electric bill is outrageous with the ac running almost non stop. 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. I have 2 whirley bird turbins. Not all turbines will fit all roof pitches.

Much like a window this round vent is powered by the wind. 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. Step 3 clear any obstructions away from the turbines by pulling them free. Also barely using my finger of course they spin freely no noise etc.

I ve gone on the roof and white lithium greased both and but a level on them and they are pretty close to level. This is a standard turbine vent. My attic is extremely hot during the summer. If you decide to add more turbine vents to your roof be sure to buy ones that are aluminum.

It houses a circular fan that s very sensitive to breezes. As it spins the air blown from the vent is strong enough to blow rain away from the openings between the fins. 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.

The turbines are adjustable so that the spinning part is level even though the roof is slanted. Do i have a low pressure system. The wind has to blow pretty hard for them to turn good. Turbine fans have no power other than wind so when the wind is not blowing the turbine does not turn.

Normally the force of even slight breezes will cause the turbine vent to spin. The faster the wind speed the faster the turbine rotates.
