Hello,
I have two of those round wind driven roof turbines on my home. They were apparently installed by the prior owner. One of them has stopped spinning. Are those things something that requires lubrication, or since it's stopped spinning I can assume it needs to be replaced? If lubrication is the problem, what should I use? If I have to replace it, is that something a homeowner with Zero prior experience could tackle or do I have to have a roofer come out for the job?
Thank you,
Steve
