The roof is on–I ordered 81 sheets needing 80 but thought that one extra would be a good idea….in case of damage, so to speak. Sure enough, the top sheet was damaged, but guess what? They only shipped 80. They gladly shipped another sheet up to me (this is not economical as they’re 16′ long, crated, trucked from Oregon to Seattle, then barged to Petersburg…… Guess what? Wrong color. Meanwhile, I’m on the road so can’t deal with this at the moment.
