[quote=Hobie]NSR: Not the area to seal the vent. It needs to be outside on the roof. Another close up pic please, and a roof vent shot.[/quote]
LOL, I didn’t seal it there, I sealed it outside. I identified where it was leaking from the inside, through the nail that’s in the flashing. That little bright spot behind the vent stack is a drip in motion.
I proceeded to go outside on the roof in the rain to check the nail and flashing. A little pressure showed water was wicking from the outside edge of the flashing over to the nail between the flashing and shingle basically reaching the unprotected part of the nail driven through them providing the access point.
I resealed the nail on top, and seal the edge of the flashing back to the shingles that are on top of the flashing. While attempting, in the growing dark, wind and rain to insure that I wasn’t creating a mini-dam to trap the water.
So yeah, tomorrow being a sunny day will another climb back on the roof day and touch up my emergency patch.
BTW, thanks for the advice and pointers, it is appreciated.
I didn’t change anything in the attic picture, that’s the way it is, cruddy ancient insulation, skip lather cedar shingle detritus and whatever the hell the wrap is on the vent stack.
