Standard Roof Pitch Degrees

Roof pitches exceeding the level of 9 12 or approximately 37 degrees are termed steep slope roofs.

Standard roof pitch degrees.

These are utilized in residential applications. Locate its tangent or tan and follow the left row for you to read its corresponding degree. Most roof s have a pitch in the 4 12 to 9 12 range. Determine its angle through taking a 12 inch level and.

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. The pros and cons of aluminum roofing. 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.

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. Pitches above 9 12 are very highly angled and are designated steep slope roofs. Select the best roof trusses and budget amount. 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.

Divide its rise by run in. This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees. The most commonly used roof pitches fall in a range between 4 12 and 9 12. How do you calculate the slope of a roof.

Pitches lower than 4 12 have a slight angle and they are defined as low slope roofs. The following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72. Basic about roof pitches common roof pitches different roof pitches fundamentals roof pitch roof pitch degrees roof pitches ideas standard roof pitch. This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement.

Pitches of less than 2 12 are considered flat roofs even though they may be very slightly angled. As aforementioned there is no standard pitch of a roof. Common roof pitches and equivalent grade degree and radian angles. Roof slope expressed as rise.

Some of the most common roof pitch types are conventional slope type roofs designed with pitch ranging from 4 12 to 9 12. 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. But the most commonly used pitches range between 4 12 and 9 12.
