Roof Turbines Not Turning

If yours aren t turning it s time to lubricate or replace entirely.

Roof turbines not turning.

A turbine may fail to spin if the bearings become rusty or. This is a standard turbine vent. If the vent is rusted it may be sticking and not turning as it should and this can lead to water infiltration. The maximum roof pitch is almost always printed on the box label.

Not all turbines will fit all roof pitches. Finally be sure the ball bearings are permanently lubricated and sealed. The one thing i ll mention is that turbine vents need to be installed perfectly level. When they re not installed level they don t turn.

2 of my 3 turbine vents on my roof won t turn unless there s a stronger wind. It doesn t take much wind to turn your turbine roof vents. You can usually adjust the level by turning the turbine body. 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.

Climb up into your attic and look at the vents from the inside. If the vents are blocked by insulation boxes or. You may have to replace the turbine with an electric fan type of ventilator. Just hot air rising out of one will make it spin.

There may also be something near or in the vent that is stopping it from turning. The turbines are adjustable so that the spinning part is level even though the roof is slanted. Do you see anything else that s wrong in the photo. The hot air is exiting the roof through the louvers at each end of the roof as they were designed to do.

Do i have a low pressure system. Nothing is more bothersome in the middle of a. 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. Examine the turbine from the exterior from the roof.

In the photo below the vent on the left wasn t level. Also barely using my finger of course they spin freely no noise etc. My attic turbines are not turning step 1. The faster the wind speed the faster the turbine rotates.

Walking around my soffits yes i do have soffit vents and from the attic i can see sunlight in. If they spin freely but just sit there when on your roof i d say they aren t level.
