roof plywood size?

I am going to be reroofing my garage shortly ( complete tearoff) and I will need to be replacing some of the existing plywood as well. I haven't been able to get up there to see what size it is but is there a norm to what size they use. A local roofing supply house told me most of there jobs they quote
1/2". Does that sound right. Garage was built about 20 years ago.

1/2" or 5/8" would be common, but you will want to match what is there for repair work. If replacing it all, you will want to use what your municipality requires. Check with your building inspector for that number.

If you have access to the underside of the roof, look for the ink APA stamp on the bottom of the plywood, it will tell what size it is. (If the manufacturer was an APA member.)
