Roof pitch conversion.

To find the angle of a roof in degrees convert the pitch to a slope then convert to degrees by finding the arc tangent of the slope. However if you to do the process using your own knowledge you can still convert pitch to degrees by dividing the rise and run and get its corresponding measurement. To do this simply convert the rise and run as a fraction to a decimal form eg. With the use of this converter it will be easier for you to locate a 30 degree roof pitch 20 degree roof pitch 25 degree roof pitch or a 15 degree roof pitch.

Rise run rise run slope. The charts are there to provide people with an idea of what the actual slope will. How to convert roof pitch to degrees.
