2 12 Pitch Roof Degrees

The exact roof slope in degrees is given by the arctangent.

2 12 pitch roof degrees.

Resilient asphalt shingles lie much flatter to the substrate than slate tile and concrete which keeps water from being easily blown under them. Roof pitch angle roof pitch multiplier 1 12 4 76 1 0035 2 12 9 46 1 0138. However if you to do the process using your own knowledge you can still convert pitch to degrees by dividing the rise and run and get its corresponding measurement. 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 reference 2 12 equates to about 9 5º and 4 12 to about 18 5º. 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. 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. Some roof specifications may express slope in the typical geometric terms of degrees.

If your house roof is built with multiple pitches then square per roof must be calculated differently. A 12 12 pitch roof has a pitch angle of 45. Find the inverse tangent of the pitch to find the angle in degrees. To convert between american roofing ratios and pitch degrees follow these steps.

Enter any pitch or fraction of pitch to find angle. Roof pitch degree table. What roof angle in degrees. Divide the first part of the ratio by 12 to work out the pitch.

45 this is our pitch calculator which will convert pitch to angle or angle to pitch for half degree roof slope calculations. This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees. Thus pitch is typically greater in areas of high rain or snowfall. At slopes below 2 12 a granule surfaced asphalt membrane can be installed and many are available in colors to complement the shingle colors.

The following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72. Arctan 3 12 14 0 the primary purpose of pitching a roof is to redirect water and snow. Definitions vary on when a roof is considered pitched. The table below shows common roof pitches and the equivalent grade degrees and radians for each.

Enter any angle or fraction of angle to find pitch. 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. In degrees 10 2 in 12 or 1 in 6 is considered a minimum. What degree angle is a 12 12 pitch roof.
