Shed Roof Formulas
$$text{Rise} = text{Adjusted Run} times frac{X}{12}, quad text{Slope Length} = text{Adjusted Run} times sqrt{1 + left(frac{X}{12}right)^2}$$
$$text{Total Surface Area} = text{Adjusted Length} times text{Slope Length}$$
A shed roof (mono-pitch or skillion) features a single continuous roof plane sloping in one direction, common on porches, additions, and modern residences.
