Vent Pipe Flashing - Resealing

I'm in the middle of a bathroom remodel and, while all the sheet rock was down from the ceiling, I noticed I could see daylight next to a vent pipe. This is a 3" cast iron vent pipe that seems to have slightly separated from the flashing. Can anyone suggest the best method of repairing this?

I am hoping to replace the roof this spring or next fall, so I am not expecting a repair to last 25 years or anything...but I do want a good repair.


EDIT: Just to be clear, the separation is at the top of the flashing where it makes contact (or should) with the pipe. I'm hoping that it is as easy as re-caulking (if so - product recommendations would be appreciate).

You can use Henry's fiber cement in a tube to "caulk" the flashing around the pipe, BUT, when you do your roof, be sure to replace the flashing with a new one.
