Next, you take into account the slope of the roof, as that will affect amount of materials needed, a 4:12 slope and for the given example in the calculation will have a multiplier of 1.05 of the total.
Complex roofs will need you to simplify the shape into geometric figures like triangles or rectangles. Manually rooftops that are more complicated like gambrel roofs with steep slopes will need to have a separate calculation for the upper and lower sections to obtain an accurate measurement.
