Horizontal to vertical slope ratio to 1 percent slope degrees slope slope ratio.
Roof slope conversion tables.
18 4o inches per foot.
Most roof s have a pitch in the 4 12 to 9 12 range.
4 3 1 slope.
Slope as grade for an elevation of 1 m over a distance of 2 m can be calculated as.
The combination of two numbers are used to display or show the roof pitch.
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.
Roof pitch is the slope created by the rafter.
If this isn t practical then perform the same measurement on the underside of the roof.
To obtain an accurate roof pitch measurement properly measure the rise and run.

Run horizontal distance from rise2 50 0 208 11 77.
Roof pitch refers to the measurement of the slope of a roof and you express this as a ratio.
The following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72.
Roof pitch degree table.
Roof pitch conversion charts are very useful for one thing they give you all the information that you need to provide to the professionals.
To see what the degree equivalents are for standard rise in run roof pitches see our page quick reference.
The charts are there to provide people with an idea of what the actual slope will.
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.
Roof slope expressed as rise.
Line to roof surface.
The table below shows common roof pitches and the equivalent grade degrees and radians for each.
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.
If you can give them the exact chart and measurement that you like the look of they can work to those specifications.
Image 1 12 to 12 12 roof pitch 7 12 pitch.
Using a tape measure make a pencil mark 12 inches from the end of a carpenter s level.
Example slope as grade.
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.
Horizontal surface to roof surface1 50 0 125 7 12 2 00 0 167 9 46.
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.
3 1 or 3 to 1 percent slope.
Two most common methods 4 12 or 4 12 are used for marking the pitch of a roof.
