Simply locate a roof rafter board place the end of the level against the bottom edge and measure from the 12 inch mark vertically to the bottom edge of the rafter.
This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement.
These roofs have a pitch less than 4 12.
Angle the angle of a roof is the same as the roof s slope except instead of being.
10 12 roof pitch equivalents roof rises 10 in a length of 12.
Roof slope style.
