Overall, in installing a whole roofing area, OSB will cost you $700 to $1,000 cheaper than plywood.

Why is OSB Cheaper?

The reason why OSB is cheaper is basically that the board is engineered. It is made out of strands of different types of wood, added by gluing and strengthening material. It can be made in larger sheets, and of course, it covers a larger area than plywood. That is why it is way cheaper than plywood.

OSB vs. Plywood Strength

Roofing is an important part of the house. It is basically the part to protect from the weather. That is why roofing is all about strength. Any material to provide roofing must be durable and sturdy. It has to be able to endure the weather, too.

OSB vs Plywood Strength

OSB vs. Plywood Screw Holding

Screwe holding ability is a critical matter in roofing. When the roofing material cannot hold nails and screws properly, of course, it cannot hold its shape very well. This is why you need to know the screw holding ability between plywood vs. OSB for roofing.

OSB vs Plywood Screw Holding

The full information will be displayed down below so that you will know which one is better.

Screw Holding Ability of OSB

Both OSB and plywood have great tolerance to keep nails and screws together. OSB is engineered, and they can hold screws quite well. However, when the screws are removed, it may damage the strands of wood on the OSB and makes it a bit weaker.

Screw Holding Ability of Plywood

Plywood has better performance in holding the screw. It can be used easily when you need to install and remove the screws. Plywood is also still more natural, and the screws will basically stay intact on the wood, even when they get rusty. This is why plywood has a better score in the screw holding ability compared to OSB.

Based on those explanations, it is clear that both plywood and OSB have their own strength and durability. Both of them are great for roofing. Plywood has better performance when it comes to overall durability.

However, OSB is a lot cheaper and more affordable to buy. In the end, it will be your consideration to choose between performance and cost. Eventually, you can decide which one to use between plywood vs. OSB for roofing.
