To convert between american roofing ratios and pitch degrees follow these steps.
Angle the angle of a roof is the same as the roof s slope except instead of being.
Slope the slope of a roof is represented as x 12 where x is the number of inches in rise for every 12 inches of run this is very useful information for many purposes especially for roof framing the slope sometimes called pitch is calibrated on speed squares.
For instance a 7 12 roof pitch means that the roof rises 7 inches for every 12 horizontal inches.
As a result the tiles must be able to cope particularly at the lower end of the slope with the greater expected volume of water and lower speed of water movement.

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 lower the pitch the greater the amount of water that the roof slope will collect and discharge.
Roof pitch refers to the measurement of the slope of a roof and you express this as a ratio.
Most roof s have a pitch in the 4 12 to 9 12 range.
