When we added onto the house about 18 years ago (maybe more) I put green tin on the roof over 1/2 OSB. No problems. Old part of the house put purlins over asphalt (two layers) and screwed down green tin. Was told the same thing about the expansion and contraction against asphalt scratched the underside causing the roof to rust out from bottom up. I went single sheet from top to bottom.

We get about 6” of rain a year, most of it in about an hour during one storm.

The deck is currently 1/2" CDX, would putting down a second

Or is that just a waste of money.
I think it is a bit excessive.

The tile acted as an insulator, would not let the fire vent, and also hid the location of how far the fire had spread.

I should be okay there; as I replace a lot of the plywood last time I had the roof off as I knew there were issues.
