Why is plywood used in roofing?

In roofing, plywood is often selected due to its strength. Although the roof structure takes the majority of the weight, plywood needs to be able to support the rest of the roofing system. It is formed from multiple layers of wood bonded together with glue, and the grains run in alternate directions through each layer, which ensures the board’s strength is evenly spread, makes the board resistant to shrinking or expansion, and also reduces the likelihood of any splitting when nailed. Plywood is often used in roofing because it performs well when exposed to moisture over long periods of time. When plywood gets wet, it swells evenly across the plywood sheet, and then when it dries out it goes back to the normal sizing. The drying out period is relatively short, which means that it doesn’t affect the roofing. In comparison, OSB board tends to swell along the edges and takes a lot longer to dry out, which can leave visible ridges along the edges of the boards (unless it is marine grade OSB which has been manufactured for use on boats).

What types of plywood are there?

There are two types of plywood used in roofing construction – structural and general plywood. Structural plywood has proof of strength performance provided by the supplier and indicates it has passed the building regulations to be used for structural use in a building. General plywood does not have this proof of strength performance so should not be used for structural applications. Shuttering plywood is another type of plywood but it generally isn’t used in roofing. Instead, it is used to hold concrete whilst it sets. Generally, plywood comes in 4 by 8-foot sheets, and in a variety of grades. Each side is rated A to D, with A being of the highest quality and with no imperfections or knots, which can potentially lead to weaknesses in the sheet, and D grade is generally unsanded plywood that can have defects and knotholes of up to 2.5 inches. A-grade plywood is the most costly but can be combined with D-grade plywood if the side graded D is on the underside. CDX is the most common form of plywood, with a C-grade side and D-grade side, and the X stands for the glue that bonds the sheets together. Although not made of the highest quality sheets, it is often considered the strongest due to the glue used to seal it together.

Should a shed be anchored?

Sheds should be anchored to the earth or the proper base, such as cement slabs. One of the main reasons for this is that a strong gust of wind could knock your shed off its foundation. This will result in substantial damage that is expensive to restore.

diyshedsandplans.com - Do I Need To Anchor My Shed? / It Depends... - DIY Sheds and Plans

Many people ask “Do I need to anchor my shed? Does it really matter?” Well, it depends on size, climate, zoning laws, and other factors. Many sheds require and should have some anchoring. If not, they are more likely to be displaced by strong winds or shifting weather conditions such as seasonal freezing and thawing, which could induce ground displacement under your shed surface. Even a fraction of an inch of shed movement will cause havoc on your shed doors. Floor rotation will cause your doors to get out of balance, making it very difficult to open and shut your doors, and this will only worsen over the lifespan of your shed. You could also be dealing with a dangerous situation in which the roof framing is breached, which may be the worst-case scenario.
