  • easy to install but make sure you get the roof pitch right.i didn’t! had to redo.watch video on youtube.
  • I have used these Lomanco whirlybird turbines before. They work great and have long service. This order was three turbines and one of them was damaged. I was able to fix it and use it so I did not send it back. We were in the midst of the job when I opened the box with the damaged whirlybird so I had no choice but to try and make it work. Should have checked all three out upon delivery instead of just one.
