Standard Roof Pitch Degrees

Divide its rise by run in.

Standard roof pitch degrees.

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. Roof pitches exceeding the level of 9 12 or approximately 37 degrees are termed steep slope roofs. These are utilized in residential applications.

Pitches above 9 12 are very highly angled and are designated steep slope roofs. 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. Roof slope expressed as rise. 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 rise will be equal to the amount of the incline within the given distance or the run that. To see what the degree equivalents are for standard rise in run roof pitches see our page quick reference. As aforementioned there is no standard pitch of a roof. Most roof s have a pitch in the 4 12 to 9 12 range.

The following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72. The pros and cons of aluminum roofing. Roof pitch and corresponding angles. Common roof pitches and equivalent grade degree and radian angles.

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. 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. Basic about roof pitches common roof pitches different roof pitches fundamentals roof pitch roof pitch degrees roof pitches ideas standard roof pitch. Some of the most common roof pitch types are conventional slope type roofs designed with pitch ranging from 4 12 to 9 12.

Locate its tangent or tan and follow the left row for you to read its corresponding degree. How do you calculate the slope of a roof. Select the best roof trusses and budget amount. Pitches lower than 4 12 have a slight angle and they are defined as low slope roofs.

Identify the rise and run. The most commonly used roof pitches fall in a range between 4 12 and 9 12. This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees.
