Welcome to the forums

Local codes might dictate what you can or can't use.

IMO plywood is better than osb. 5/8" is better than 1/2"
1/2" OSB is what's most commonly used.

depending on the size of the project I would probably go with the regular 1/2" OSB. I agree that ply and thicker is better but the OSB is lighter and cheaper and industry standard. Whatever you use don't forget the spacers

Industry Standard?

Is it Industry Standard because it's light & cheap or is it a product that competes with similar performance as the plywood?

I'm trying to make choice of the 2- right now & would appreciate a bit more discussion on the topic.

Thanks, -Willie

Price is the main reason osb is used. As long as it is covered osb should last just as long as plywood. Remember even the old tongue and groove decking that was common place for roof decking years ago would deteriate if the roofing wasn't maintained.

Personally I prefer plywood but my wallet likes osb better

I have the same question. I want to go with comp shingles but my dad says that 1/2 inch is to thin to hold the nails/staples and that I should only use 1/2 inch when screwing on tin. Is this true?

Shingles are nailed onto 1/2" osb/ply all the time although I'm sure 5/8" would be better.
