I have one of those round roof vents on my house (someone told me it's called a gravity vent).

The round cover has a fist size dent on one side and the silver metal "collar" that attaches to the cover and the roof/flashing is folded down on one side. I was wondering if it had been struck by lightning, but, consulted one of the local lightning guys by email and he said maybe but hard to tell without a visual inspection.

I'm not sure if this is just a cosmetic issue or something that needs to be repaired or replaced. Any recommendations on who to contact or consult?

Photo is not that clear but you can zoom in to see how the collar is folded down.
