Lower slopes don t handle wind driven rain as well.

12 12 roof pitch 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. To see what the degree equivalents are for standard rise in run roof pitches see our page quick reference. Degrees to roof pitch rise in run to see a table. Divide its rise by run in.

To convert between american roofing ratios and pitch degrees follow these steps. The rise will be equal to the amount of the incline within the given distance or the run that. Roof slope expressed as rise. Roof pitch and corresponding angles.

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. Locate its tangent or tan and follow the left row for you to read its corresponding degree. This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees. A 12 12 pitch roof has a pitch angle of 45.

It s just a little math. Steeper slopes increase the sail effect that makes them susceptible to wind. See below after the table for directions on how to convert any roof slope from one form to another even roof slopes not shown in the table. Identify the rise and run.

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 table below shows common roof pitches and the equivalent grade degrees and radians for each. The following table shows how the same common roof slopes can be expressed using rise in run ratios degrees and percentages.
