Vent Pipe Leak

[raymond]

We are remodeling our entire full bathroom. We started because we thought the toilet had leaked several times and damaged the floor. We ripped all the sheetrock/drywall down. We got some rain yesterday and noticed that the toilet/gas vent pipe has actually been causing the damage not the toilet itself. We replaced the roof 3 years ago with a metal roof, put on new vent boot and flashing and have put tar ALL around it. We got in the attic last night to see where the water could be coming from...NOTHING. No holes or anything. Any suggestions on where the water could be coming from? Its dripping from the 2x6 at the ceiling where the vent pipe is running down the drywall onto the floor and into our basement.
Thanks!!

Metal roof?

First off, the metal roof should be pappered below. Otherwise, the warm moist air from the attic will condense on the cold metal roof.

Since it happened while it rained, it more likely is from the vent pentatration. Someone may need to take a look up there.

The vent never holds water, so it would be very unlikely for it to leak any rainwater that happened to go into the pipe.

I agree with Terry that the roof is the most likely suspect.
