4 12 roof pitch to angle 18 43 degrees. What roof angle in degrees. Other than the 45 roof slope which is 12 in 12 none of the standard roof pitches 5 in 12 6 in 12 etc are equal to a whole degree. Next find the degrees by finding the arc tangent of the slope eg.

Let s find the angle in degrees for a roof with a 4 in 12 pitch. 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. In that case the multiplier is multiplied by the run of the rafter the horizontal distance that will be covered by the rafter. Enter any pitch or fraction of pitch to find angle.

This forms an angle of 18 5 between the horizontal section and the roof and creates a gentle incline that is seen as a midpoint between a low pitch and medium pitch roof. For this you can take help from roof pitch factor chart. The roof pitch factor is also used to calculate the length of common rafters.
