Even if you want to use a flat roof pitch calculator system you will be able to find one.

If you want to know how to find the pitch of a roof then start with a calculator.
The rise is the height of the roof and the run is the horizontal span as pictured above.
Pitch rise run 1 5 6 25.
Calculate the rafter length substituting these values into the following formula.
The pitch is commonly defined as the ratio of rise over run in the form of x 12.
For example if a roof has a pitch of 4 12 then for every 12 inches the building extends horizontally it rises 4 inches.
Calculate the roof pitch as the proportion of rise and run.
Position your level against the roof until the bubble of the vial sits between two lines.
For example a roof that rises 6 inches for every 12 inches of the horizontal run has a 6 in 12 pitch.
This will allow your project to carry the depth and detail in the roof that you wanted as well as make sure that it will maintain a sturdy and effective nature throughout.
Measure the rise of your roof.
Before taking any measurements you must first confirm that it s safe to walk on your roof.
Rafter rise run 1 5 6 2 25 36 38 25rafter 38 25 6 18 m.
Let s say it is equal to 1 5 m.
First find the slope by finding the tangent of the degrees eg.
Take a measurement of 12 inches using a level.
However carpenters typically make use of diverse finders of roof pitch angles an example of that is being a rafter.
Then multiply the slope by 12 to get the rise.
If you know the angle of the roof in degrees you can find the roof pitch by converting the angle in degrees to a slope then finding the rise by multiplying the slope by 12.
Slope tan degrees.
Pitch of any roof can be computed by the number of inches it grows vertically for every 12 inches it extends horizontally.
