On blue prints architects engineers usually display the pitch of a roof in the format shown on the image where number 4 represents a rise and number 12 represents a length.
Roof 45 degree wall angle.
The pitches on the drawing are given on a 45 angle.
Angles in a floor plan are not inherently bad however they should be there for a reason to solve a problem creatively.
This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees.
Most roof s have a pitch in the 4 12 to 9 12 range.
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.
A pitch over 9 12 is considered a steep slope roof between 2 12 and 4 12 is considered a low slope roof and less than 2 12 is considered a flat roof.
The triangle diagram will be re drawn to scale with all dimensions marked.
Enter run the flat level length then click pitch angle or rise to select then enter other known dimension angle or pitch.
Angle the angle of a roof is the same as the roof s slope except instead of being.

Roof pitch calculator results explained.
This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement.
If we know the angle and the length of the roof we can calculate the height of the roof that we will need later in order to calculate the area of the roof.
If we draw a notional line vertically from h i to k their pitch will be 45.

The hips at the ends are also at 45.
