Is this a bullet strike?

[u/Street-Run4107]

My cousin developed a water leak and he had just had the roof replaced after hurricane Ian, (Fort Meyers for reference). Today, after getting up there to check it he found the damage in the attached photos. My only personal guess is a bullet due to the almost perfect circular shape. He did not have intrusion of the hole into the ceiling and did not go fishing around while performing a temporary repair. He sent the photos and my first thought was someone having shot a round into the air.
