Recommended Thickness Of Shed Roof Sheathing

OSB vs. Plywood: Which Should You Choose for Your Roof Deck?

The recommended thickness for roof decking on a shed is . At that thickness, you can economically sheath your shed while still getting an extremely solid roof substrate that will stand the test of time.

OSB board is preferable to plywood for sheathing a shed. Strand board that is tongue and groove makes for a very straightforward install on your shed. If your rafters or shed trusses are widely spaced, or uneven then the tongue and groove give the edges additional strength, particularly if they arent supported by framing at every edge.

The strand board, besides being cheaper, also works extremely well with tar paper. The rough surface of OSB as compared to the smoother surface of plywood allows the tar paper to hold better and makes installation much faster.

And while plywood may dry faster than strand board, its important to note that all strand board roof decking you buy these days has blue edges. That means the edges have been waterproofed, which makes it much less likely water will penetrate the board. The adhesives that bond the strand board are also waterproof.

You could always opt for thicker roof deck panels, but for a shed there is no need to go thicker if your framing is of standard width. Once you start buying panels that are greater than thick, youll notice the cost rise significantly.

The thickness of the plywood can be controlled by the number of plies glued together. Oriented standard board is created much differently. If you take a look at a sheet of OSB, youll notice the surface isnt extremely smooth. This is because OSB is created by taking woodchips, gluing them together, and hot-pressing them down. This process takes the original wood chips and condenses them into solid sheets. The thickness of OSB is controlled the same way plywood is. The more wood chips there are, the thicker the OSB will be.

    What Happens If Plywood Is Stored In Wet Conditions

    Generally, if common plywood gets wet for an extended period of time, it can swell and lose shape which eventually leads to the layers of wood splitting apart. This often occurs when plywood is stored outside for even a short timeframe before a project begins. However, this issue can be fixed. If the plywood is dried out quickly and efficiently, it can remain unaffected and undamaged in the long term, maintaining its full strength and durability for safe and reliable use.

    How Is Plywood Used In Roofing

    Plywood is usually used as a form of roof decking, the material that is placed on top of the roofing structure.

    While we often think of the main roof structure as being what needs to be strong and handle large amounts of weight, the roof decking is a component that has to be strong enough to support the entire system from collapse!

    Since decking is made from layers of wood that are glued together, the grains of the wood run in alternate directions throughout each layer. This gives an even distribution of the woods strength so that its resistant to contracting and expanding. This also prevents it from being weak that it splits when a nail goes through it.

    In case youre wondering, roof decking is one of the most important structures of your roofing system. This is made up of wooden boards that produce the roof frame.

    These boards are basically what your roof shingles and other roofing elements are installed on, so you have to ensure that the decking is strong enough to handle all their weight.

    There are good reasons why plywood is ideal for decking construction. These include the following:

    Where Did Plywood Come From

Depicted on a carving in Thebes, it is shown that the Egyptians used to utilise plywood to construct stools, furniture, tables and even tomb cases as far back as 3500 BC. The manufacturing process was similar to that practised today with sawn veneers glued together in cross graining.

    Probably its most fundamental era of use, plywood also played a key role all throughout World War II. Thanks to its impressive strength and durability, plywood was used to construct barracks, weapons, boats and even planes with the introduction of higher-grade synthetic water-resistant glues that ensured much sturdier installation.
