Sorry for the fuzzy picture, I took it from a window. We noted several yellow faint ceiling stains along a rafter, not wet at this time and not sure how long they have been there. This vent pipe sits about 10ft. up, yet in line with these stains. Roofer is coming on Tuesday to check things out. From what I can see, the rubber around the pipe is intact but everything I have researched indicates that the lower or skirt part of the flashing should be above the shingles, not under them. Could this be causing a leak. Thanks!

Yes the lower side of the metal is usually visible above the shingles.

Thanks! Do you think this could be the cause of the leak?

 

[Windows on Wash]

Yes. The low side of the flange is supposed to be on top of the shingles.

Thank you for your responses.

Do you have an attic space between ceiling and roof?

 

[PTgirl]

No it is a vaulted ceiling

Someplace I read somebody suggesting that you can bleach out water stain in a ceiling and it can save you from having to repaint. I'm skeptical if that really works, but it could be cool if it does. I never tried it. Probably takes some strong bleach solution.
Maybe you can be a guinea pig on that one.

It does seem like the flashing around that pipe is wrong. That could be the problem and you would obviously still have to get that fixed.

it works 50/50 with water in a spritz bottle, I did it on popcorn ceiling.
Cover anything and everything with poly first.
