2 12 Roof Pitch In Degrees

To convert between american roofing ratios and pitch degrees follow these steps.

2 12 roof pitch in degrees.

A 12 12 pitch roof has a pitch angle of 45. Enter any pitch or fraction of pitch to find angle. What roof angle in degrees. 2 12 roof pitch angle 9 46 degrees.

Conventional forms range from 4 12 9 12 and steep slope roofing is more than 9 12 and requires extra fasteners. What degree angle is a 12 12 pitch roof. Find the inverse tangent of the pitch to find the angle in degrees. The table below shows common roof pitches and the equivalent grade degrees and radians for each.

For this you can take help from roof pitch factor chart. At slopes below 2 12 a granule surfaced asphalt membrane can be installed and many are available in colors to complement the shingle colors. Resilient asphalt shingles lie much flatter to the substrate than slate tile and concrete which keeps water from being easily blown under them. Enter any angle or fraction of angle to find pitch.

Pitch has a basic range but it s not uniformly defined however the range from flat that is not perfectly flat but is sloped in order to drain water is up to 12 2 12. 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. Most roof s have a pitch in the 4 12 to 9 12 range. For reference 2 12 equates to about 9 5º and 4 12 to about 18 5º.

Roof pitch degree table. This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees. 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. 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.

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. 45 this is our pitch calculator which will convert pitch to angle or angle to pitch for half degree roof slope calculations. Divide the first part of the ratio by 12 to work out the pitch.

If a roof rises 2 in a length of 12 this is 2 12 roof pitch.
