The exact roof slope in degrees is given by the arctangent.
1 12 roof pitch house.
Think of a classic addams family haunted house with its soaring peaks and you have a picture of a high pitched roof.
Most roof s have a pitch in the 4 12 to 9 12 range.
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.
This is one of the rare pitches where the numerator is greater than.
Roofs on victorian era houses were often sharply angled with a steep pitch.
However you can only use this pitch with built up roofing or specialized synthetic roofing.

Arctan 3 12 14 0 the primary purpose of pitching a roof is to redirect water and snow.
We included a roof pitch chart below the 7 12 example image and the calculator below that.
If this isn t practical then perform the same measurement on the underside of the roof.
0 pitch 1 00x the roof area.
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.
Thus pitch is typically greater in areas of high rain or snowfall.
1 12 roof pitch angle 4 76 degrees.
Image 1 12 to 12 12 roof pitch 7 12 pitch.
The minimum pitch for a roof is 1 4 12 which translates to 1 4 inch rise to 12 inches of run.
Visually this roof appears flat.
The table below shows common roof pitches and the equivalent grade degrees and radians for each.
If a roof rises 1 in a length of 12 this is 1 12 roof pitch.
Since this is a flat roof or nearly flat roof.
You can go by the measurements taken by walking the roof.
Definitions vary on when a roof is considered pitched.
In degrees 10 2 in 12 or 1 in 6 is considered a minimum.
