Then area of roofing sheet 3 6 x 1 8 6 48m2.
How to measure roofing sheets.
Now find out the length and breadth of each roofing sheet and also.
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.
Assuming the ceilling sheet is 3 6m in length and 1 8m in breadth.
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.
Multiply length by breadth.
Pitch measurement method 1 1.
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.
S1 s2 and s3.
Therefore total numbers of roofing sheets needed approximately is.
Once you have the area you can divide by the area of a sheet of plywood to find the number of sheets needed.
Now find out the length and breadth of each roofing sheet and also multiply length by breadth.
Since s2 is now a rectangle simple l x w is all that is required.
Determine the width and length of the metal sheets to be used.
8 inches and you have an 8 in 12 pitch.
The easiest way to measure this section is to divide it up into three different sections.
A 4 8 sheet of plywood is 32 ft 2.
Obtain the data from the manufacturer s specifications or by direct measurement.
For example if your roof is 1 500 ft 2 then it will take 47 sheets of plywood to sheath it.
