Slope Factor For 6 12 Roof

The angle for 6 12 is 26 57 and in grades it is described as 50.

Slope factor for 6 12 roof. This 6 12 roof pitch factor can also be described in other measures. Roof pitch or slope is a measure of vertical rise to horizontal run expressed in inches per foot. If this isn t practical then perform the same measurement on the underside of the roof. A a roof with a 6 rise for every 12 run has a 6 per foot or 6 in 12 pitch.

Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs. As 6 is half of 12 it is considered to be 50. Image 1 12 to 12 12 roof pitch 7 12 pitch. A 12 in 12 pitch is a steep 45 degree angle roof.

This will give you the rise over run or pitch. For example if the pitch of the roof is 6 then it is written as 6 12. Grades are the measure of percentage. Roof pitch degree table.

Simply locate a roof rafter board place the end of the level against the bottom edge and measure from the 12 inch mark vertically to the bottom edge of the rafter. Pitch is thus the ratio of the rise in inches to a 12 inch run and is often expressed using a semicolon for example 6 12. Roof pitch is a determining factor for cost of the roof as well as the roof area and the type of materials used.

See the image below for more explanation on rise run and pitch. A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally. One medium to describe the roof pitch is in 12 runs. Therefore your slope factor for a 6 12 pitch roof is 1 118.

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. For instance a 7 12 roof pitch means that the roof rises 7 inches for every 12 horizontal inches. We included a roof pitch chart below the 7 12 example image and the calculator below that.
