We have R-30!
E.G. took a look around up there (attic) and was happy with what he saw overall. Too hot, even on a not-very-hot day, but no signs of beasties (bats, rats), no leakage, etc. One of the dormers in sozlet's room sprung a leak after a truly torrential rainstorm, our first real leak in this house (there was this enormous saggy blister behind the paint, E.G. held up a bucket and popped it and water came gushing out, then it kept dripping until a bit after the rain stopped). Either one of the roofing guys sabotaged it when he was up there to make sure we felt some urgency, or this is good timing.
All the roofers (3 so far) have said whoa, that's one messed-up roof. (The old one). Seems like we've been lucky to NOT have any leaks until now.
The guy who came today seemed really good, we're hoping his estimate isn't in the stratosphere. Evidently this is a complicated roof, and the pitch doesn't help. (It's not 12/12 after all, it's a
16/b]-inch rise, 12-inch run.)
