How to measure roofing sheets.

A 4 8 sheet of plywood is 32 ft 2. Pitch measurement method 1 1. Standard sheets in the u s are 36 inches wide but the. The easiest way to measure this section is to divide it up into three different sections.

Multiply length by breadth. S1 s2 and s3. Assuming the ceilling sheet is 3 6m in length and 1 8m in breadth then area of roofing sheet 3 6 x 1 8 6 48m2 therefore total numbers of roofing sheets needed approximately is area of building allowance area of one roofing sheet 583 2 6 48m 90 sheets. Once you have the area you can divide by the area of a sheet of plywood to find the number of sheets needed.

If this distance measures 4 inches you have a 4 in 12 pitch. On a ladder beside the roof place the level a foot or so up the roof hold it level and measure from the 12 inch mark on the level s bottom straight down to the roof. Therefore total numbers of roofing sheets needed approximately is. As you can see s1 and s3 are the same size but you still need to document all measurement points to verify your material calculation accuracy.

So dividing the area of the roof by 32 will give you the number of sheets needed. Now find out the length and breadth of each roofing sheet and also. For example if your roof is 1 500 ft 2 then it will take 47 sheets of plywood to sheath it. 8 inches and you have an 8 in 12 pitch.

Assuming the ceilling sheet is 3 6m in length and 1 8m in breadth. Since s2 is now a rectangle simple l x w is all that is required.
