How To Measure Roofing Sheets

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.

How to measure roofing sheets.

S1 s2 and s3. Once you have the area you can divide by the area of a sheet of plywood to find the number of sheets needed. Obtain the data from the manufacturer s specifications or by direct measurement. Now find out the length and breadth of each roofing sheet and also.

Multiply length by breadth. For example if your roof is 1 500 ft 2 then it will take 47 sheets of plywood to sheath it. 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. A 4 8 sheet of plywood is 32 ft 2.

Determine the width and length of the metal sheets to be used. If this distance measures 4 inches you have a 4 in 12 pitch. Therefore total numbers of roofing sheets needed approximately is. 8 inches and you have an 8 in 12 pitch.

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. The easiest way to measure this section is to divide it up into three different sections. 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.

Pitch measurement method 1 1. So dividing the area of the roof by 32 will give you the number of sheets needed.
