you should put a vapor barrier down first. I prefer Titanium UDL but 30# felt will work.

Okay I'm putting on a R panel metal roof this weekend, and I am pulling off one layer of singles. The decking is 1x4 as far as I can tell. What should I put down on the decking if anything before the metal?

Give your area of the country, you may want to consider some radiant barrier application as well.
