House built in 1950 in Georgia in the Southeastern US. Front of the house: The circled eve vent is what I'm chasing. The interesting thing is that I can't find it. There's one on each corner of the house where the two sides meet in a point and those two are readily accessible and visible from each end of the attic. The middle part of the attic is a room that you can stand up in all the way across (the black area). The crawl space area in red is this all the way across: In between the roof joists in the pic above, you can see the roof nails sticking out of the roof boards, so this is clearly the slant of the roof. They have some old junk up there that nobody bothered to throw away, mainly old boards with nails sticking out) that I had to shove aside. I went nearly halfway across the house and to the second awning from the right, and there was nothing visible in regards to the vent or any opening. At the corner of the house, I can see a little bit of drywall visible from in the attic crawl space that is clearly the area where it angles up, but I don't see a vent or opening anywhere (oh and yes, it is very icky up there, as expected).
