So my investigation was not optimal. I was overly optimistic. On the amount of space in that section of the attic. Not to mention the number of nails sticking through from the roofers.
The wet spot is in the corner next to the converted kitchen 70s style box fluorescent light. That means I have the width of a kitch cabinet between it and the wall in the attic and the raised section.
Complaining aside. I wasnt able to get really close and didn’t see obvious water running of signs of. Saw what appeared to be prior water on some of the old insulation. Didn’t see any wet staining on the wood but didn’t get the best view due to being several feet away, craning my neck and peering thru LCD light in the dust
That said the water damage appeared centered around the waste drain vent pipe for the kitchen sink. No signs of water coming from the roof so I’m wondering if it’s possible for the pipe to be leaking on the bends from back flow? It’s a pipe to provide air/gas venting, if excessive rain/water is getting in how problematic is that?
I checked the pipe outside and the flashing looks good but noticed the pipe doesn’t have any kind of cap and it’s right next to the solar panels on the downslope side and below the edge of the panel. And by checked I mean looked at from the ladder several feet away and I’m not climbing unto the wet roof in the rain to thoroughly investigate. That’ll be a job for Tuesday.
Could the water be running off the solar panel into the vent pipe and then leaking at the joints? It’s one of those older looking cone shaped vents that then has a straight pipe up out of it. How is the black PVC vent pipe connected to the flashing and external pipe normally?
