Lower slopes don t handle wind driven rain as well.
45 this is our pitch calculator which will convert pitch to angle or angle to pitch for half degree roof slope calculations.
A 12 12 pitch roof has a pitch angle of 45.
Steeper slopes increase the sail effect that makes them susceptible to wind.
On blue prints architects engineers usually display the pitch of a roof in the format shown on the image where number 4 represents a rise and number 12 represents a length.

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.
Most roof s have a pitch in the 4 12 to 9 12 range.
Divide the first part of the ratio by 12 to work out the pitch.
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.
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.
A 30 degree roof slope 7 12 pitch is the right pitch to aerodynamically handle high wind.
Enter run the flat level length then click pitch angle or rise to select then enter other known dimension angle or pitch.
