A gable roof has an equal pitch slope on each side of the ridge.
1 12 pitch gable roof.
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.
Find the inverse tangent of the pitch to find the angle in degrees.
The peak high point of the gable roof is 12 from the sidewall and located at the center of the building.

The table below shows common roof pitches and the equivalent grade degrees and radians for each.
This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement.
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.
Gable roof framing calculator plan diagram with full dimensions for a good straight fascia add an extra inch or 2 to the tails of all your rafters total length.
