Standard Roof Pitch Degrees

These are utilized in residential applications.

Standard roof pitch degrees.

The picture below shows the pitch of a 7 12 roof slope meaning that for 12 of horizontal measurement roof run the vertical measurement roof rise is 7. The most commonly used roof pitches fall in a range between 4 12 and 9 12. Roof slope expressed as rise. This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees.

The pros and cons of aluminum roofing. Locate its tangent or tan and follow the left row for you to read its corresponding degree. Common roof pitches and equivalent grade degree and radian angles. You write the pitch assuming a run of 12 inches thus the ratio would describe how much a roof rises for each foot of the run.

The following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72. The rise will be equal to the amount of the incline within the given distance or the run that. But the most commonly used pitches range between 4 12 and 9 12. Select the best roof trusses and budget amount.

Basic about roof pitches common roof pitches different roof pitches fundamentals roof pitch roof pitch degrees roof pitches ideas standard roof pitch. 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. As aforementioned there is no standard pitch of a roof. Most roof s have a pitch in the 4 12 to 9 12 range.

To see what the degree equivalents are for standard rise in run roof pitches see our page quick reference. How do you calculate the slope of a roof. Pitches of less than 2 12 are considered flat roofs even though they may be very slightly angled. 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.

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. Pitches lower than 4 12 have a slight angle and they are defined as low slope roofs. Determine its angle through taking a 12 inch level and. Pitches above 9 12 are very highly angled and are designated steep slope roofs.

Divide its rise by run in. Roof pitch and corresponding angles. This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement.
