How Much Plywood Do I Need For My Roof

No calculator can tell how much waste will be on each run plywood.

How much plywood do i need for my roof.

The number you ll get is the number of sheets that you need. For rafters spaced 20 or more inches apart 1 2 or 5 8 inch plywood is recommended. The square footage of a hip roof area is identical to the square footage of a gable roof of the same measurements. Add at least six feet for waste.

This basically calculates the number of sheets needed for a gable roof. The most common size for plywood sheets is 4 x 8 feet followed by 5 x 5 feet. Add an additional 10 for waste and mistakes. 800 32 25 sheets.

Divide that by 32 the square footage of each 4 8 plywood sheet. 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. For a shape like a circle pentagon hexagon or octagon find 25 of the width and measure the length at that point. After all it keeps water out of the building.

A typical 4 foot by 8 foot sheet of plywood covers 32 square feet. Let s say that your roof has a total of 1 500 square feet. Estimate the amount of plywood or osb needed for sheathing a roof. Divide the roof s area by 32 32 is the total area of one sheet of plywood to find this figure.

We also carry pre cut project panels that are available in different sizes that may vary by store. So dividing the area of the roof by 32 will give you the number of sheets needed. A 4 8 sheet of plywood is 32 ft 2. The roof is arguably the most important component of your house.

For example if your roof is 3 000 square feet divide 3 000 by 32. In this case you need 47 sheets rounded off from 46 88. Divide the total roof area by 32 to get the number of sheets you will need to cover the roof. A 4 8 sheet of plywood is 32 ft 2.

The most common rafter spacing is 24 inches and 5 8 inch plywood is recommended for that. And while nobody likes having to pay to replace a roof the critical and aesthetic function it serves should help ease the pain of spending 8 000 to 20 000 on the work. It will support roof. 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.

These project panels help eliminate waste cut costs and are easier to transport than full size panels. This comes out to about 94 sheets of 4 x 8 plywood. The calculation is based on that the plywood or osb oriented strand board sheets are of a 4 x 8 size. That is dependent on the lay out and where it ends with the plywood.

For example if your roof is 1 500 ft 2 then it will take 47 sheets of plywood to sheath it. Multiply the width and length of each slope and you should get the square footage of that slope.
