Well I think I've got it fixed, the gasket around the vent was cracked pretty good so I sealed that up good... but those cracks didn't just suddenly happen so I wonder how long it's had a leak. Where it is positioned in the house I could have seen evidence if it had been leaking much. I think the amount required to ruin that wall came from under the flashing. I could tell it was lifted some. Roofing company still hasn't returned my call so I will go to another.
Of course I get into the crawl space an hour ago to get the Christmas decorations and see that the sump quit pumping and there was about 6" of standing water. Got that back going and now It's running wide open... and will be for a while.
