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.
1 12 roof pitch house.
If a roof rises 1 in a length of 12 this is 1 12 roof pitch.
Roof pitch degree table.
In degrees 10 2 in 12 or 1 in 6 is considered a minimum.
If this isn t practical then perform the same measurement on the underside of the roof.
This pitch might be as low as 1 12.

Think of a classic addams family haunted house with its soaring peaks and you have a picture of a high pitched roof.
1 12 roof pitch angle 4 76 degrees.
Roofs on victorian era houses were often sharply angled with a steep pitch.
You can go by the measurements taken by walking the roof.
Resilient asphalt shingles lie much flatter to the substrate than slate tile and concrete which keeps water from being easily blown under them.
This is one of the rare pitches where the numerator is greater than.
Visually this roof appears flat.
The exact roof slope in degrees is given by the arctangent.
Thus pitch is typically greater in areas of high rain or snowfall.
Most roof s have a pitch in the 4 12 to 9 12 range.
The minimum pitch for a roof is 1 4 12 which translates to 1 4 inch rise to 12 inches of run.
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.
However you can only use this pitch with built up roofing or specialized synthetic roofing.
The table below shows common roof pitches and the equivalent grade degrees and radians for each.
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.
