Roof framing elevation.
This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement.

Bow roofs appear gable like but the slopes are curved.
The advantages of hip roofs apply to this framing style.

From the eaves to the peak it s 10 feet high that s the rise.
Say your house is 38 feet wide and the gable roof has a 1 foot overhang on each side.
Interior grade steel framing triple coated for superior durability.
Line length is the hyptenuse of the triangle whose base equals the total run and whose altitude equals the total rise.

For example if the slope is 4 in 12 and the run is 12 feet the ridge beam height m will be 4 feet.
The slopes are steep.

If the unit of rise in inches is 3 then the cut is the unit of rise and the unit of run 12 inches or 3 12.
Roof terminology is also not rigidly defined.
If you know the slope x in 12 you want to use for your roof framing design you can use it along with the run r to determine the height of the ridge beam.
1 8 pitch is given so 24 x 1 8 equals 3 or unit of rise in inches.

The main factors which influence the shape of roofs are the climate and the materials available for roof structure and the outer covering.
The picture below shows the pitch of a 7 12 roof slope meaning that for 12 of horizontal measurement roof run the vertical measurement roof rise is 7.
