Introduction
When it comes to roofing, one of the most important decisions you’ll make is what size OSB board to use. This boards are typically available in four foot by eight foot sheets, but they can also be found in four foot by ten foot sheets. The thickness of the boards varies, but most roofing applications calls for three-quarter inch thick boards.
There are a few considerations that go into choosing the right size OSB board for your roofing project. The first is the span of your rafters. The span is the distance from the outside edge of one rafter to the outside edge of the next rafter. Square footage of your roof will also play a role in determining what size OSB board you need.
For example, if you have 24 foot long rafters with a span of 16 feet, you would need two sheets of four foot by eight foot OSB board for each row of rafters. On the other hand, if you have 30 foot long rafters with a span of 20 feet, you would need two sheets of four foot by ten foot OSB board for each row of rafters. It’s important to note that these are just examples and your specific project may require more or less OSB board.
Once you’ve determined how much OSB board you need for your project, you’ll also need to decide on the type of sheathing that’s right for you. There are two basic types of sheathing: structural and non-structural. Structural sheathing is made up of thicker boards that are intended to add strength and stability to a structure, while non-structural sheathing is thinner and designed primarily for weather protection. Depending on the needs of your project, either type of sheathing could be a good choice.
If you’re still not sure what size or type of OSB board is right for your project, consult with a professional contractor or builder before making a purchase. They will be able to give you more specific advice based on the individual needs of your project.

What Size OSB Board Do You Need for Roofing?

If you have a larger roof or a flat roof, you may need a bigger board, such as 4 feet by 10 feet or even 4 feet by 12 feet. Be sure to measure your roof before making any decisions so you know exactly how much material you’ll need.
