It would still help if you had some pictures, but regardless, could you have had animal damage? I had woodpecker damage last fall and had to have a roof replaced. There was discussion if it was either tree limb damage or an animal chewing on the roof, but I had chased a woodpecker away twice and feel confident that's what it was. Tree limb damage will cause scrape marks and occasionally leave bark residue under the ripped roof edges. Just a thought.
