2 12 Pitch Roof Degrees

A pitch of 2 12 is the minimum pitch for shingles made of asphalt so your roof just barely makes the cut off for one of the most popular roofing material options.

2 12 pitch roof degrees.

In degrees 10 2 in 12 or 1 in 6 is considered a minimum. 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. For this you can take help from roof pitch factor chart. The table below shows common roof pitches and the equivalent grade degrees and radians for each.

At slopes below 2 12 a granule surfaced asphalt membrane can be installed and many are available in colors to complement the shingle colors. If your house roof is built with multiple pitches then square per roof must be calculated differently. Find the inverse tangent of the pitch to find the angle in degrees. Some roof specifications may express slope in the typical geometric terms of degrees.

With the use of this converter it will be easier for you to locate a 30 degree roof pitch 20 degree roof pitch 25 degree roof pitch or a 15 degree roof pitch. 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. The exact roof slope in degrees is given by the arctangent.

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. Enter any pitch or fraction of pitch to find angle. What roof angle in degrees. Enter any angle or fraction of angle to find 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. A 12 12 pitch roof has a pitch angle of 45. Arctan 3 12 14 0 the primary purpose of pitching a roof is to redirect water and snow. Resilient asphalt shingles lie much flatter to the substrate than slate tile and concrete which keeps water from being easily blown under them.

For reference 2 12 equates to about 9 5º and 4 12 to about 18 5º. Roof pitch degree table. Roof pitch angle roof pitch multiplier 1 12 4 76 1 0035 2 12 9 46 1 0138. What degree angle is a 12 12 pitch roof.

Definitions vary on when a roof is considered pitched. Thus pitch is typically greater in areas of high rain or snowfall. The following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72. This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees.
