Can I use a 1 1/4" PSE sheathing between the lats and not worry about moisture? I'm replacing a metal roof with metal roof.

It has 1 1/2' lats. Need to know if i need to worry abouts rotting of the lats from moisture or is the 1/4' air between PSE (Expanded polystyrene) and metal roof adequate.The roof is vented Do i need to use the foiled back PSE and if so which way to face the foil

If you have a vented attic, I assume your insulation is at your ceiling level. If this is the case, there is no need to add insulation at the roof...
