2 12 Roof Pitch In Degrees

Enter any pitch or fraction of pitch to find angle.

2 12 roof pitch in degrees.

To convert between american roofing ratios and pitch degrees follow these steps. This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees. Divide the first part of the ratio by 12 to work out the pitch. What roof angle in degrees.

2 12 roof pitch angle 9 46 degrees. Enter any angle or fraction of angle to find pitch. If a roof rises 2 in a length of 12 this is 2 12 roof pitch. Conventional forms range from 4 12 9 12 and steep slope roofing is more than 9 12 and requires extra fasteners.

A 12 12 pitch roof has a pitch angle of 45. The following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72. For reference 2 12 equates to about 9 5º and 4 12 to about 18 5º. If your house roof is built with multiple pitches then square per roof must be calculated differently.

At slopes below 2 12 a granule surfaced asphalt membrane can be installed and many are available in colors to complement the shingle colors. Roof pitch angle roof pitch multiplier 1 12 4 76 1 0035 2 12 9 46 1 0138. 45 this is our pitch calculator which will convert pitch to angle or angle to pitch for half degree roof slope calculations. What degree angle is a 12 12 pitch roof.

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. Find the inverse tangent of the pitch to find the angle in degrees. Roof pitch degree table. Some roof specifications may express slope in the typical geometric terms of degrees.

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. 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. Resilient asphalt shingles lie much flatter to the substrate than slate tile and concrete which keeps water from being easily blown under them. Most roof s have a pitch in the 4 12 to 9 12 range.

The table below shows common roof pitches and the equivalent grade degrees and radians for each.
