Attic inspection of roof leak at a bathroom vent pipe

This homeowner called about a possible roof leak from water damage they noticed inside at an interior wall. I did an inspection of the roof and it appears that the damage was old but to be sure I told them I'd come back on a rainy day to go in the attic and look. The damage inside was at an interior wall on both sides of the wall in between a bedroom and a bathroom. Typically with a leak like this it is usually because of a vent pipe going through the wall and the flashing has gone bad at some point. Going in the Attic on a rainy day to observe if it is dry or wet is a good way to find out if it's currently leaking or if the damage was old.

Hi there, you have a lot a value to everyone. The way I’ve been watching you explain things on the inspection is vital information. This gives me and others out there things to look for and how to prevent future damage. Keep on doing your thing, it works and super easy to understand 🎃

Good info here. I'm dealing with the same thing. I ended up opening a soffit vent and used my phone with a selfie stick to get a video of the leak. :-)

Hello your video sent me in the right direction. I think it was an old leak. I have a newer roof the wood around the toilet PVC gas release pipe is rotted. I will be checking on the roof tomorrow. I found this when I was putting a new bathroom fan in and almost put my hand through the rotted wood around the pipe!

I'm suspecting a vent pipe is the source of my leak, however I only see water on my basement floor around the sewer stack during a very heavy rain and made sure it wasn't the actual plumbing lines around it. Isn't coming through the basement wall either. My roof is only 5 years old so I don't think it's the actual roof. Thank you for the insight👍

I had a vent pipe leak similar to this last September. It leaked once about 2 months after we moved in and I saw the stain where the ceiling meets the wall. We ended up having a new metal roof put on later (for different reasons, shingles were shot and totally gone IMO) and it leaked again at the same spot because the new boot wasn't installed properly with the new roof. Owner came out and sealed it up and it's been fine since. But it's weird the old boot only did it that one time. I never understood how it leaked just that one time. Before the new roof was put on, we had a leak one time at one of our dormers in a really weird spot. I guess water penetrated somewhere higher and ran down where the dormer met our interior wall. Only did it that one time too. No clue. That old roof was in bad shape, and yet, our inspector said it had "at least 5 years left before needing replacement." We had 5 leaks going simultaneously and deck rot that looked pretty advanced. Now, I have some worry about some rafter spacing that is slightly bowed above my garage and the main story. That same inspector said it was rafter spacing, at least. Nobody said anything about it when the new roof was put on. Who knows... Love your vids though. :)

Great quality video. Never seen this type of info before. I'll be sucking out my old fiberglass and putting in R-49 in the near future. I think you recommended to do fiberglass vs. cellulous? I'll always have my N-95 out now for going in the attic as you suggested earlier with the live you did a few hours ago that perhaps didn't last as to not a good reception. Ohhhhhhhhhh, 0.3k from giveaway!

Man that pipe can easily get clogged suppose to be 2” all the way

[@bobgriffith4551]

Why would not you have dug you got the big mask on it's probably leaking from inside the pipe I do about a half dozen of these a year they never glued the joint or somebody put a screw through it and it finally rusted out I bet you that or when they nailed the boot down the dummy's nailed face nailed into the bottom of the boot

[@bobgriffith4551]

I guess if you put on a mask like that and go up into the Attic you can jack the price up

[@GrandRoofingInc]

There was no price jacking there was not even a charge for that.

Brian is an honest guy who sometimes does not even charge for a simple fix.
