The combination of two numbers are used to display or show the roof pitch.
Slope as grade for an elevation of 1 m over a distance of 2 m can be calculated as.
Roof slope expressed as rise.
Two most common methods 4 12 or 4 12 are used for marking the pitch of a roof.
Roof pitch degree table.
Roof pitch on the form x 12 can be expressed in grades as.

We included a roof pitch chart below the 7 12 example image and the calculator below that.
Roof pitch refers to the measurement of the slope of a roof and you express this as a ratio.
Using a tape measure make a pencil mark 12 inches from the end of a carpenter s level.
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.
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.

Although there s isn t any standard pitch of a roof used on all kinds of sloped roofs you can determine the range of pitches by using a roof angle calculator and by considering factors like the local climate and roofing materials.
To see what the degree equivalents are for standard rise in run roof pitches see our page quick reference.
The following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72.
Then you ll be able to measure slope from an unfinished attic space under the roof.

You can find the roof pitch in the form of x 12 like 4 12 or 9 12.
If this isn t practical then perform the same measurement on the underside of the roof.
Roof pitch conversion charts are very useful for one thing they give you all the information that you need to provide to the professionals.
If you can give them the exact chart and measurement that you like the look of they can work to those specifications.

The charts are there to provide people with an idea of what the actual slope will.
Roof pitch is the slope created by the rafter.
To obtain an accurate roof pitch measurement properly measure the rise and run.
The table below shows common roof pitches and the equivalent grade degrees and radians for each.
