That's a monster! I broke up a bunch the other day, but now we have water leaking on some interior walls here. I removed some sheetrock and insulation and there's ice on the inside of the wall, on the sheathing. waaaahhhhhh!
It's turning into a big deal. The roof is fine, but the gutters have to come down so I can replace the fascia board with aluminum, and remove the siding. There's no barrier behind the siding! No tar paper, no builder's paper, no tyvek, nothing. But, it's a good chance to put in a new window.
The insurance company can't get here for two more weeks, lots of houses are like this, I guess. At least the wood floor downstairs wasn't trashed.
