Roof vent flashing

Just had a roof done and when looking at the vent flashing some of the flashing on the down side of the slope is nailed to the shingle. I thought nailing is a no no. Also, some vents are nail and others are not. The ones that are nailed are not sealed in any way. Can't water work it's way down the nail hole. Any thoughts would be appreciated.

If you can see the nail heads, water can enter. Tell the guy you want him to seal them.
