The angle, or pitch, of a roof is calculated by the number of inches it rises vertically for every 12 inches it extends horizontally.
Roof pitch is rise and run. So if you have a 4/12 pitch, for every foot of run the roof rises 4 inches.
In general, talking about roof pitch, I have never heard or read about this term being used. Roof pitch is measured when you start at the leading edge of a roof and measure towards the center of the house too 12 feet. Pitch is measured from a imaginary parallel level line at the 12 foot mark, how many feet high the roof is at 12 feet is the pitch of a roof. If your roof is at 4 feet high at the 12 foot mark then the phrase would be- a 4/12 pitch.
A roof angle of 6 degrees = 1.26 / 12 rise or pitch.
If you do not have access to a roof framing book, I would use a tape and measure it. Length x width = square footage. My book says you should come up with : 11.33 x 12 = 135.96 sq ft

You can figure it out with a roof framing book if you know the span and pitch of the roof. Its usually quicker to climb up there with a tape.
Use a plastic compass to determine the angle of the roof in relation to the horizontal, then find the pitch based on the angle. Angle to pitch ratios are available on the web.
It depends on how big and what materials you are using. A minimum of 5 degrees from center is usually considered safe from collapse if you are using strong roof planks/trusses.
A single pitch roof is basically a flat roof with a pitch (or angle), usually to allow water to run off. This differs from a double pitch roof /\ that is what you commonly see.
Roof pitch is measured in "rise over run". In other words, how many inches does the roof rise vertically in 12" of horizontal run. If a roof rises 4" in 12" of run, you have a 4/12 roof pitch.

Pitch is a bitumen or it can mean the slope of the roof for example 1/8" per foot fall
