Angle the angle of a roof is the same as the roof s slope except instead of being. Roof pitch is a measurement of a roof s slope expressed as a ratio. Commonly it is 3 4 th of span as per gothic rafter must be equal to span.

A mono truss is a one sloped truss that forms a right angle triangle. This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement. Roof pitch angle and slope factor charts. Greek says one must keep rafter length in range of 1 9 to 1 7 th of span but as per roman style the standard dimensions are kept about 1 3 to 2 9 th of span with an angle of 23 to 24 degree.

If this isn t practical then perform the same measurement on the underside of the roof. You will also incur additional costs because it is much harder to deck and shingle a roof that is 12 12 pitch versus a 4 12 roof.
