Roof Turbine Not Spinning

The turbines are adjustable so that the spinning part is level even though the roof is slanted.

Roof turbine not spinning.

New roof turbine not spinning. Our turbine roof vents whirlybirds were really noisy and had some rattling that was causing some vibration in the house. Both houses are standard single story houses with gable roofs. 2 of my 3 turbine vents on my roof won t turn unless there s a stronger wind.

The turbine on the house next door is spinning as are a few others down the street but this one isn t. In addition pay attention to the maximum roof pitch that will work with the turbines. The maximum roof pitch is almost always printed on the box label. Since they are only 4 years old i m guessing they were replacements so maybe the wrong ones were installed not all turbines work with all roof pitches or these just haven t been leveled correctly.

Do i have a low pressure system. Step 3 clear any obstructions away from the turbines by pulling them free. 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. I ve gone on the roof and white lithium greased both and but a level on them and they are pretty close to level.

It was very annoying. If they spin freely but just sit there when on your roof i d say they aren t level. Also barely using my finger of course they spin freely no noise etc. The turbine spins freely when i turn it by hand with very little effort no squeaks and no resistance.

Examine the turbine from the exterior from the roof. I installed a basic aluminum 12 roof turbine on the back side of a house yesterday but it s not spinning.
