Some time during the night or early morning, about a quarter of the garage ceiling collapsed, dumping all of the blow-in insulation it previously held onto the floor and one of the hobby tables.
I quite calmly finished the process of making coffee (okay, not entirely calmly; I did say "what the fuck" out loud) and ensured there was a full pot brewed before I went back upstairs to wake David and quietly inform him, "We have a small problem in the garage." Wasn't that thoughtful of me?
Not surprisingly, David's immediate response exactly echoed mine: "What the fuck?"
A somewhat closer inspection made clear what the problem was. As you can see below, on a section that had not yet collapsed you can see the gap between the drywall and the rafter beams it is supposed to be attached to. That's not good.
Oh, yeah, and did I mention the ceiling fan was hung without being secured to an electrical box attached to a rafter? So, yeah, both of them were dangling another foot-plus into the room.
Once we started getting into the clean-up and tearing down the portions of drywall that were clearly ready to fall, it became apparent the cause of the collapse: The contractor who hung the ceiling used nails instead of screws, and only placed them every two feet on every second rafter beam. They used blow-in insulation (probably because the space above the garage was originally attic), which over time absorbed moisture from our lovely, humid climate, which added weight to the ceiling. Compounded with the vibration of the garage door being opened and closed several times a day over the course of three decades, and you've got a bunch of ever-loosening nails.
Now, we realized shortly after the bought the house that the original builder had taken some shortcuts (my understanding is that at the time of construction Georgia had few or no actual building codes for residential), and that the sellers had done all of their "upgrades" on the cheap. But, we really did not expect to have the ceiling collapse in the middle of the night. We're just grateful no one was in there when it did.
