Contractor just left the house

he did everything well. i was just curious as to what went on first being an inquisitive individual.
i believe he said he put down drip edge along the eaves and rake edge. then he put down ice shield OVER the drip edge along the eaves. he then put ice shield in the valley’s and drip edge under flashing around chimmney and vent pipes. then he laid the felt paper over everything.this seems right?
he then apologized for using my roof as a motel but insisted it was in every ones best interest(whatever that means; the roof looks good.
