I have recently been working on insulating our attic, which had no insulation prior. I have confirmed that I cannot find a way into the ceiling part of the upper bath from the attic to insulate it. I possibly could if I could figure out exactly where to saw into the roof planking to make an opening, but I really don't think that's a great idea.
It gets darn cold in the upstairs bath, as exposed as it is, and likely with little if any side wall insulation too. So I'm tossing around a few ideas.
1) It is a 1/2 bath (7'9" x 5' 10"), and although I'd rather not, I could insulate the ceiling by removing same, then restoring the ceiling after.
2) Since we know the roof was done in two parts, with the back of house being the older repair, we will likely need at least a new back half roof within a few years or less. Should we wait until then to go in from the outside instead of destroying the current ceiling which appears to be original?
3) If we're to go from the outside in, should we at least insulate the walls since we plan to fix the badly done "upgrade" in there anyhoo? It could be managed on budget this winter if this is better than nothing. However, my concern is would it be bad to insulate the walls before the roof over that room? I've not been able to find an answer to whether insulating at least the exterior walls is better than nothing, or if it's worse somehow because the roof above isn't.
Any
