In general, plywood for roofing is between half an inch and three inches thick. However, most roofs are sheathed in plywood that is at least three-eighths of an inch thick. The thickness you choose depends on a number of factors, including the country you’re in, the anticipated load on the roof, and the weather conditions. If you’re building a flat roof, you’ll need to make sure to choose a thicker piece of plywood.

Each type has its benefits and drawbacks.

Another type of plywood is CDX. This material has an X in its name. The X is for exposure, and many people mistakenly think the X means exterior.

Some OSB variants are even treated with building wrap.
Plywood is a popular choice for roofing. It is made of several sheets of wood bonded together. The interlocking grain of the wood prevents warping, swelling, and other problems that can occur when wood is exposed to moisture. It also dries out much faster than OSB board, which tends to swell in the corners and edges. Plywood also dries faster and is less likely to show visible ridges.
