Roof Turbine Not Spinning

Do i have a low pressure system.

Roof turbine not spinning. Both houses are standard single story houses with gable roofs. The turbine spins freely when i turn it by hand with very little effort no squeaks and no resistance. 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.

It was very annoying. If they spin freely but just sit there when on your roof i d say they aren t level. Step 3 clear any obstructions away from the turbines by pulling them free. 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.

Not all turbines will fit all roof pitches. Our turbine roof vents whirlybirds were really noisy and had some rattling that was causing some vibration in the house. New roof turbine not spinning. The maximum roof pitch is almost always printed on the box label.

In addition pay attention to the maximum roof pitch that will work with the turbines. The turbine on the house next door is spinning as are a few others down the street but this one isn t. 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.

I installed a basic aluminum 12 roof turbine on the back side of a house yesterday but it s not spinning. The turbines are adjustable so that the spinning part is level even though the roof is slanted.
