I’m seriously annoyed.
We finally got part of the ceiling torn out in T’s bedroom, and discovered that we can see daylight coming in around half of her A/C duct, which means there’s this eight-inch long gap communicating directly to the outside. Hell, no wonder it leaks with a bloody great hole like that up there! L’s proposing that I take some leftover roof flashing and make a collar to go around the duct, seated in a bed of roofing cement, and see if we can’t create a seal that way. I’m not at all convinced it’ll work because I don’t know that it’s possible to make a bed of roofing cement thick enough and even enough that we’ll get a seal all round, but damn if I can think of a better solution right now. Maybe if I can rivet the flashing in place first after I seat it and then slap another thick coat of roofing cement on top, it’ll make something that’s halfway tight. One thing’s certain, and that is it won’t do as it is now, so we have to find some solution before we can put up the new ceiling.
