For a simple gable roof as shown in pic 1 with length of 25.2m. First you must know the height of roof from the section. For this sample we are taken the eight to be 3meters (10 feet)to know the length of leaf “x” or “y” Remember the pythagoras theorem x2=32 +6.12 x=6.8m Hence the area of roof is (6.8 i.e x)+6.8 i.e y) multiply by length 25.2m=342.72m2 If the width of the roof comes in 600mm or 0.6m, the length of the roof ...
