Opinions on the cause of this issue?

We have had an issue with rodents in our attic. The remediation company came out today to seal entry points and lay traps when he came down he asked if I had my roof done recently, I had it done 3 years ago. He stated they did a crap job and shared these photos. He stated that it was damage done when replaying the roof. I shared the photos with the roofing company and they said it was the rats. Exterminator stated that rats chew in a circular area not along a line. I wanted to get your thoughts on this.
