How Much Plywood Do I Need For My Roof

That is dependent on the lay out and where it ends with the plywood.

How much plywood do i need for my roof.

One sheet 32 ft. For example if the area to be covered in plywood is 800 ft 2 then 25 sheets of plywood will be needed to cover it. Add an additional 10 for waste and mistakes. This basically calculates the number of sheets needed for a gable roof.

A 4 8 sheet of plywood is 32 ft 2. Divide the total roof area by 32 to get the number of sheets you will need to cover the roof. Estimate the amount of plywood or osb needed for sheathing a roof. The number you ll get is the number of sheets that you need.

1 500 32 46 875 sheets. In this case you need 47 sheets rounded off from 46 88. The roof is arguably the most important component of your house. Multiply that by 2 if you have a gable roof and that s the total square footage of your roof.

For a shape like a circle pentagon hexagon or octagon find 25 of the width and measure the length at that point. Divide that by 32 the square footage of each 4 8 plywood sheet. These project panels help eliminate waste cut costs and are easier to transport than full size panels. Multiply the width and length of each slope and you should get the square footage of that slope.

No calculator can tell how much waste will be on each run plywood. Let s say that your roof has a total of 1 500 square feet. The square footage of a hip roof area is identical to the square footage of a gable roof of the same measurements. Divide the roof s area by 32 32 is the total area of one sheet of plywood to find this figure.

The most common size for plywood sheets is 4 x 8 feet followed by 5 x 5 feet. After all it keeps water out of the building. Add at least six feet for waste. We also carry pre cut project panels that are available in different sizes that may vary by store.

The most common rafter spacing is 24 inches and 5 8 inch plywood is recommended for that. 800 32 25 sheets. The calculation is based on that the plywood or osb oriented strand board sheets are of a 4 x 8 size. A 4 8 sheet of plywood is 32 ft 2.

For example if your roof is 1 500 ft 2 then it will take 47 sheets of plywood to sheath it. For example if your roof is 3 000 square feet divide 3 000 by 32. A typical 4 foot by 8 foot sheet of plywood covers 32 square feet. It will support roof.

Divide by the total square footage by the square footage of a sheet of plywood to find the number of sheets required to cover the space. So dividing the area of the roof by 32 will give you the number of sheets needed.
