Roof Pitch Finder

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 roof pitch is the slope of the rafter. Calculate the roof pitch as the proportion of rise and run. 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. Rafter rise run 1 5 6 2 25 36 38 25rafter 38 25 6 18 m. Calculate the rafter length substituting these values into the following formula. Pitch of any roof can be computed by the number of inches it grows vertically for every 12 inches it extends horizontally.

Take the measurement of the vertical. Position your level against the roof until the bubble of the vial sits between two lines. Let s say it is equal to 1 5 m. Measure the rise of your roof.

For example a roof that rises 6 inches for every 12 inches of the horizontal run has a 6 in 12 pitch. Check the surface of the. Take a measurement of 12 inches using a level. Pitch rise run 1 5 6 25.

First find the slope by finding the tangent of the degrees eg. The rise is the height of the roof and the run is the horizontal span as pictured above. Then multiply the slope by 12 to get the rise. The pitch is commonly defined as the ratio of rise over run in the form of x 12.

Before taking any measurements you must first confirm that it s safe to walk on your roof.
