What kind of plywood should I buy to roof my house?

This topic is available here on The Repair-Place forum
I am confused about plywood. It comes in different thicknesses and differnt types. Wht type and thickness should I get to roof my house?
Roof plywood should be 5/8" cdx exterior grade plywood for spans less than 24" between roof rafters. You could use thinner plywood like 1/2" but I wouldn't. There also should be a spacer between sheets along the grain of 1/16" to allow for expansion.
