What type of fan are you using at your vent, how is it powered, and switched on/off?

It's a simple fan with it's own sensor that turns it on at around 110 deg F.
Looks a bit like this one.
When I first installed it, I was standing on the ground about 18 feet below it,
and I could feel the blast of very hot air coming down on my head!!
It was installed during the 1980s and I'm amazed that it's still working after all these years..
One thing I found out when my old roofing shingles were replaced, the tar paper underneath was so brittle,
it crumbled like saltine crackers. My Roofer told me that excess heat ages shingles a lot faster.
He won't install new shingles without installing a ridge vent, because of heat damage.
