3/4" ply is going to be more expensive and heavier to get in the attic, but it is definitely the best option if you don't want the floor sagging/bouncing when you walk. You could get away with 1/2" ply if you just are using it for storage and don't care about the bounce in the floor. Absolutely no need to use pressure treated lumber in your attic.

We did 3/4inch plywood from our local place. Had them cut the sheets into 2x8 (barely fit up the stairs due to angled roof but we lucked out).
Going on 6 years & no signs of any heat damage or compromise.
Was a PITA to carry them all up there but it’s nice to be able to walk around without fear of falling through ceiling.

I was wondering about pressure treated because that attic will get pretty damn hot in Louisiana. Plus the humidity.
I don't want to do this just to have an issue in 10-15 years and be stepping through it.
A simple google search may tell me overall what the best thing in, but whats fine in Ohio may not last as long in LA, etc.

pretty sure the 1/2 non treated I have in my attic has been up there for at least 30-40 years
it is still in perfect condition

Thanks for the serious answers guys - likely will look at either the 3/4 or the pre-cut Home Depot stuff. It will be mostly storage based but I will need to walk around some up there.

your roof deck is most likely 7/16 OSB. OSB will be fine unless it stays wet.
what will you be storing up there? 7/16 will be bouncy, but will hold up fine. nail it at each end and it will sag/bounce less you can go thicker/stiffer with the same material, but it gets heavy. rip each panel to 2'x8' and it's much easier to handle and get into the attic.

Teak.

No one is asking the correct question: What dimension lumber are your ceiling joists (do you have trusses?), how apart are they, what is the clear span underneath, and what kind of weight are you trying to put up there? Are you planning to store items, finish it into a room, etc?
Another question you should be asking is: should I insulate the cavities under the decking, move ductwork as you are able under the deck, and then air seal the top deck to the walls and tape/foam/caulk the seams to stop air leakage? Some builders actually use Zip Wall sheathing to do just that and create an air/vapor barrier that you can store stuff on top of.

1/2” plywood should be more than sufficient especially if it’s nailed (or screwed) down properly
I would steer clear of pressure treated wood in your attic due to the chemicals used and possible corrosion issues that they can cause.

Am I the only one that hates working with OSB? Nailing the edges to joists is a PITA because it's probe to splitting. I prefer good ol plywood.

1/2" regular plywood unless your roof leaks. 3/4 is a bitch carrying up into the attic and slinging around, and there's no need for even heavier pressure treated if it's in the house
Posted on 3/15/19 at 10:33 am to Tigerstark
Bro, they used OSB, more than likely, as the roofing substrate...
Posted on 3/15/19 at 10:37 am to Tigerstark
the correct answer to your question depends on what size support you have: 2x6's, 2x8's, etc.

Yeah...but there's a wide variety. 3/4 inch pressure treated? Or just cheap 1/2 inch?
Doesnt matter IF you have a well designed attick. There should be no moisture up there (definitely not enough to rot wood...duh)

What do you guys suggest?
Foolproof way to never fall through.
Many problems can be solved simply by merely reframing the question.
