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.
Grade A plywood is the highest grade of plywood. Its appearance may be a bit unappealing, but it’s still sturdy and water resistant. Grade B plywood is not quite as good as grade A, but it can be a good choice for undersides. There are three main grades of plywood: B-grade, grade C, and grade D. Each type has its benefits and drawbacks.
CDX plywood is another type of plywood for roofing. This is an inexpensive choice that’s well-suited for roofing projects. It is also waterproof and resistant to drastic temperature changes. Its top layer is visible, so it’s important to choose a grade that’s durable. It can also provide a good look for your roofing project. It’s important to remember that there are various types of plywood for roofing projects, so be sure to research them before you buy.
MDO plywood is made of layers of wood veneers that overlap. The core sheets are odd-numbered, and the surface layer is made of medium density fiber. MDO plywood can be used for roofing, but it should not be reused for concrete forms. It’s also useful for soffits on buildings. If you’re looking for plywood for roofing projects, it’s a good option for the job.
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. CDX is good for interior use, but doesn’t perform as well as it should on the exterior. It is an excellent sheathing material, and many contractors use it for both subfloors and roofing. 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.
