How I fixed our Roof Turbine Ventilator. OR How to perform maintenance on a Turbine Roof Ventilator.

Our turbine roof vents (whirlybirds) were really noisy and had some rattling that was causing some vibration in the house. It was very annoying. It sounded like someone running an air compressor in the attic. I decided I was going to either fix them, or replace them. Turns out that they just needed some maintenance. So that’s what I did… These things can move a lot of air out of your attic. They use the power of the wind. I like the idea behind these things. I like the idea that they are Free to operate…they seem to work.. No cost is good..

@EdWatts Thanks for the comment!
@EdWatts Cool, I didn’t know that. Makes sense. Thanks!
Entertaining video.
The part you called a “cup spacer” is actually a “rain shield”.
Ah, No worries.. A static vent sounds like a good option. If mine were that worn out, I’d probably have gone the same route. Thanks for letting me know.
Well, I removed it and covered the hole with a lawn bag strapped with a bungie cord. Mine doesn’t have ball bearings but mere bushings. The lower bushing is worn bad. The turbine is old and it’s cousin is much newer. I looked down the hole and see a lot of dirt and leaves on the attic insulation. Not really the best design! I think I’m gonna get a static vent. The turbine serves no purpose but to keep rain out if it’s spinning. I think a screened static vent will work better. Thanks anyways!
Good Luck! It’s been about 6 months and mine are still silent..
I hope it goes well for you.
If you would, let me know if it works out for you.
Thanks and Good Luck!
I have the same exact turbine and as I type it is humming away just like the one in your video. The thing started humming at 4 am last night. I didn’t know what it was. I thought someone was drilling holes on my roof. I walked outside in 30 degree weather at 4 am trying to figure it out. I’m going on the roof today after watching your video! Thank you!
Sorry, I missed your comment.. The turbines are lightweight aluminum and it takes very little to make them stop turning. I think adding stuff to make them into a generator would cause too much drag resistance. I don’t think they would be effective as a means to generate electricity. I wish they could though..
can you connect a motors to them and generate electricity
@Dco237thEngBn -Very true on the beer…the roof does have a pretty steep pitch.. For this roof, when the time comes- I’ll have it done..Ha!
