Same thing happened to my at my house. Took the dry wall off the walls in the bathroom and came back the next day to the ceiling on the floor. Not ideal.
I was in the attic, nailing a new can light onto the ceiling joist... The 30 year old insulation paper didn't hold.
Please tell me you stuck the landing...
That sucks! What's goin' on with the blue tape?
I was just marking our planned cabinet/window/floating shelf locations
