Ceiling: the Deal.
The guys repaired the ceiling today, and as it turns out, the roof structure too. Dave told me that whoever installed the original range hood also cut into one of the roof joists. "I was kind of wondering why the roof sagged like that, that must be why," he said. The ironic thing is that the range hood that they just took out didn't even vent up to the roof; it didn't even vent anywhere, it just moved the air around above the stove. Nothing to worry about, though: Dave and his boys repaired the roof joist all tidy like, and our roof is that much more solid.
