I've read the reports here of the one piece flat roofs oil canning and folks mention the ATC corrugated roofs (which also have a pattern embossed on them) don't, I don't think one vs two piece really matters at all in this context. Those roofs are screwed down as well, so multiple variables in play.
What crossed my mind is what if a roof had a different corrugation pattern with wider bottom flats and those were lined up with the framing members to allow it to be taped down with VHB? The metal company appears to offer patterns with 1" high and either 2" or 3" low which could accommodated something like this I'd think. Probably would need to avoid embossing if taping. Does/would the corrugation likely avoid the oil canning alone...
It was a thought that crossed my mind as my build nears decisions on roof sheeting and siding.
