To convert between american roofing ratios and pitch degrees follow these steps.
For this you can take help from roof pitch factor chart.
Visit this page on your phone to directly measure pitch and angles.
The table below shows common roof pitches and the equivalent grade degrees and radians for each.
Select inches to enter decimal inches or millimeters for metric.
This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees.
For a more detailed explanation of the roof pitch multiplier see how to find the area of a sloped roof if you know the roof pitch in degrees find the secant of the slope using a scientific calculator for example if the roof pitch is 45 then sec 45 1 414213.
