The following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72.
Roof pitch conversion table.
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.
48 10 4 8.
There are many tools out there.
Roof pitch refers to the measurement of the slope of a roof and you express this as a ratio.
Roof pitch and corresponding angles.
To see what the degree equivalents are for standard rise in run roof pitches see our page quick reference.
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.
The calculator above can handle much of this math.
A roof pitch multiplier also called a roof pitch factor is a number that is multiplied by the area covered by a sloped roof to produce the area of the actual surface of the roof.
This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees.
The pitch of this roof is 4 8 12.
Roof slope expressed as rise.
What is a roof pitch chart.
Pitch tan angle use this when you express the angle of the roof pitch in degrees what is the standard pitch of a roof.
In essence a roof pitch chart is provided as a rough guide usually by a roofing company to help you see what the average roof pitches tend to be.
Now divide the rise by the multiplier to get the pitch eg.
