Roof pitch calculator results explained. A roof pitch multiplier also known as a roof pitch factor is a number that when multiplied by the area covered by a sloped roof gives the actual area of the roof.

Angle the angle of a roof is the same as the roof s slope except instead of being. The maths behind this number is that it is the square root of rise run 2 1. A gable roof is a traditional triangle shaped roof that can range from a medium pitch to sharp angled roofs. Calculate the roof slope.

For example if your tape measure found a 6 inch vertical distance to the 12 inch mark on your level the slope is 6 12 or 6 in 12. Image 1 12 to 12 12 roof pitch 7 12 pitch.
