Sheathing thickness - measure twice, cut once
Installing a roof for a screened in porch (14'x15') in New England. Rafters will be 2"x6", 16" oc. Rafters will first be covered with 1"x8" T&G for aesthetics on the underside of the roof. Will install plywood sheathing over T&G, not OSB.
What size sheathing is recommended given the T&G layer? 15/32" or ?
Thanks

What type of roofing will you be using? IMO the only reason to sheet over the T&G would be to prevent the nails from poking thru, 1/2" [15/32] should accomplish that. I'm a painter, not a roofer so if they say different - listen to them

Why two layers, if you used 2 X 6 T & G it could be done in one step.
It's done that way all the time in log cabins with exposed ceilings.

Use 3/4 if you want to be sure nothing pokes through. And I hope you are doing the roofing... I've never seen a roofer yet that won't poke a few holes in them regardless.
