Standard sheets in the u s are 36 inches wide but the.
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.
Now find out the length and breadth of each roofing sheet and also multiply length by breadth.
The easiest way to measure this section is to divide it up into three different sections.
Pitch measurement method 1 1.
For example if your roof is 1 500 ft 2 then it will take 47 sheets of plywood to sheath it.
Obtain the data from the manufacturer s specifications or by direct measurement.
Assuming the ceilling sheet is 3 6m in length and 1 8m in breadth.
8 inches and you have an 8 in 12 pitch.
Then area of roofing sheet 3 6 x 1 8 6 48m2.
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.
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.
Multiply length by breadth.
Since s2 is now a rectangle simple l x w is all that is required.
Therefore total numbers of roofing sheets needed approximately is.
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.
Once you have the area you can divide by the area of a sheet of plywood to find the number of sheets needed.
