I'm looking into finishing my attic and turn it into a man cave. I had someone look at the joist and they said it was up to code for adding a floor. There is already 1/2-in. OSB subfloor in place, but the person said I need 3/4-in. OSB. With lumber prices the way they are, can I save some money and just add another layer of 1/2-in. OSB? Or should I just rip it up and put down 3/4-in.? I just plan on putting in carpet for the floor.
Thanks for the help.
