Slope factor for 6 12 roof.

This 6 12 roof pitch factor can also be described in other measures. Roof pitch degree table. The angle for 6 12 is 26 57 and in grades it is described as 50. Outside of the u s a degree angle is typically used.

A roof pitch multiplier also called a roof pitch factor is a number that is multiplied by the area covered by a sloped roof to produce the area of the actual surface of the roof for roof slopes expressed as x in 12 rise in run the roof pitch multiplier is determined by finding the square root of rise run 1. Roof pitch or slope is a measure of vertical rise to horizontal run expressed in inches per foot. Image 1 12 to 12 12 roof pitch 7 12 pitch. A 12 in 12 pitch is a steep 45 degree angle roof.

See the image below for more explanation on rise run and pitch.

Valley hip factor. Roof pitch 6 12 roof length including overhangs 40 gable wall length including overhangs 24 enter 6 into the calculator slope factor 1 1180 multiply the roof length by the gable wall length 40 24 960 multiply this amount by the slope factor 960 1 1180 1073 28 the area of this roof 1073 3 sq. As 6 is half of 12 it is considered to be 50. For example if you measure 4 inches the pitch of your roof is 4 12.
