Roof Turbine Not Spinning

The turbine spins freely when i turn it by hand with very little effort no squeaks and no resistance.

Roof turbine not spinning.

It was very annoying. Walking around my soffits yes i do have soffit vents and from the attic i can see sunlight in. I ve gone on the roof and white lithium greased both and but a level on them and they are pretty close to level. 2 of my 3 turbine vents on my roof won t turn unless there s a stronger wind.

Examine the turbine from the exterior from the roof. Step 3 clear any obstructions away from the turbines by pulling them free. The turbine on the house next door is spinning as are a few others down the street but this one isn t. The turbines are adjustable so that the spinning part is level even though the roof is slanted.

In addition pay attention to the maximum roof pitch that will work with the turbines. Do i have a low pressure system. Also barely using my finger of course they spin freely no noise etc. 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.

These will not rust. Both houses are standard single story houses with gable roofs. I installed a basic aluminum 12 roof turbine on the back side of a house yesterday but it s not spinning. The maximum roof pitch is almost always printed on the box label.

If they spin freely but just sit there when on your roof i d say they aren t level. Our turbine roof vents whirlybirds were really noisy and had some rattling that was causing some vibration in the house.
