How much plywood for a roof.

A 4 8 sheet of plywood is 32 ft 2. This comes out to about 94 sheets of 4 x 8 plywood. It will support roof. We also carry pre cut project panels that are available in different sizes that may vary by store.

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. The square footage of a hip roof area is identical to the square footage of a gable roof of the same measurements. The calculation is based on that the plywood or osb oriented strand board sheets are of a 4 x 8 size.

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 rafters spaced 20 or more inches apart 1 2 or 5 8 inch plywood is recommended. For example if your roof is 3 000 square feet divide 3 000 by 32. A roof that lays practically flat will have a much heavier load than a steeper roof that allows rain snow and ice to roll right off.

Estimate the amount of plywood or osb needed for sheathing a roof. Add an additional 10 for waste and mistakes. 1 500 32 46 875 sheets. If your roof area is 1 600 square.

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. For example if your roof is 1 500 ft 2 then it will take 47 sheets of plywood to sheath it. These project panels help eliminate waste cut costs and are easier to transport than full size panels. A typical 4 foot by 8 foot sheet of plywood covers 32 square feet.

Divide the roof s area by 32 32 is the total area of one sheet of plywood to find this figure. 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. One sheet 32 ft.

On my shed my sheathing does not protrude actually how both my house and shed are done is a 1 x 6 house 1 x4 shed fascia is installed to end of rafters then 1 x 1 1 2 is tacked onto the fascia at the top. However you may need to consider bolstering the plywood thickness for a roof that has a higher load. Then i do a metal drip edge to cover it all. Divide the total roof area by 32 to get the number of sheets you will need to cover the roof.
