I noticed a water bubble on my bedroom ceiling, so I went in the attic to investigate. It turns out a pipe that vents to the roof had become disconnected at the first joint, so I just re-connected it. I assume when it rained hard enough, rain water was leaking down the pipe and on to the ceiling (we just had a hard rain).
But that got me thinking.. Even if the pipe didn't become disconnected, should rain water still be leaking down the pipe?
Thanks, Dan
down the inside, sure. But if it was running down the *outside* of the pipe, you probably need new flashing.

Why not? The pipe is typically square cut. It doesn't take much water to stain a ceiling.
Shhh! If water runs down the inside of the vent pipe, rainwater will enter the sewer system. This, in turn, will cause extra expense for the sanitary sewer treatment plant.
Say each house has four of these vents, each 2" in diameter, that's about a total of 12 square inches of rain capture.
Now in my town, Houston, we get about 48" of rain per year, times 12 sq in of rain capture per house, that's 4 cubic feet of water that has to be unnecessarily treated per household per year.
We have about 800,000 households, so the total waste becomes 3,200,000 cubic feet, or 24 million gallons!
If this comes to the attention of our betters, municipal ordinances will spring forth mandating rain-dispersing caps on the plumbing vents.
The good news is that these caps shouldn't cost more than $100 per house.
Hi, That sounds ??? that kind of pipe is joined male-female fashion allowing expansion, From bottom up F-M-F-M... Disconnected? More likely flashing problem?
Huh? I guess the OP just imagined seeing the pipe disconnected and reconnecting it.
Regarding his real question, any rain water that "leaks" down the vent just goes into the sewer (as another poster cleverly said). If you think about, even if it rains an inch, that's not much water compared to lets say, a toilet flush.

Yes, but fortunately I live in a right-to-scab state, so union scale is not required...
