Here's what prompted me to say "F**k it, I'm out!!" last Saturday, when I resumed tearing into the ceiling to start repairs:
You're not supposed to see daylight where the joist should be, right? And you can see the damage to the wall header (the darker bottom wood).
Closeup of the joist remains. The solid wood in front is, as near as I can tell, a nailer for the ceiling lath, and not part of the roof or wall structure.
I also started tearing out the lath and plaster that I'll need to be replacing. I was able to punch through what was there in these three bays, using only my gloved fists. (Purely a comment on the state of the walls, not my punching-fu!)
I haven't told Doc yest, because:
Saw PCP today. Did a "routine" EKG. Have been referred to a cardiologist. Apparently I have had a hear attack at some time in the past, maybe 8 years. hmmmI'm thinking she has enough on her plate right now, so I'll break this to her when that's in her rear-view mirror.
