Roof Slope Formula

Roof slope is also called as roof pitch. In civil engineering, the slope is the numerical measure of the steepness of a roof. By slope angle formula, steepness can be obtained by dividing vertical rise by horizontal span. In the imperial unit of measurements, the slope is expressed with the rise and run. It is computed by using the simple roof slope formula. It is diagrammatically expressed with a triangle shaped figure and the units are expressed in inches.

Slope Angle Formula

Formula:

Run(inches)= ( 12 × Rise ) / Roof Pitch
Slope = ( Rise / Run ) × 100
Angle = tan-1( Rise / Run )

Slope angle formula is essential to determine slope pitch as it is used by the civil engineers to determine the vertical rise in inches for every horizontal twelve-inch length. Use the roof slope formula mentioned above to find the slope of the roof by substituting the required values.
