This numerical figure is significant as not everybody can understand the technical measurements.

Pitched roof provide you protection again heavy rains.
There are lots of advantages that you can get by having pitched roof on your house as compare to flat roof.
Roof pitch and corresponding angles.
Therefore your slope factor for a 6 12 pitch roof is 1 118.
Factor charts you could calculate the slope factor for every single roof pitch but as a public service many roofing companies provide slope factor charts.
This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees.
In order to know what type of materials will work best for your project and the amount of materials required you ll need to find out the pitch of your roof.

It is sometimes called the roof pitch multiplier.
See the image below for more explanation on rise run and pitch.

The roof pitch conversion factor is a number that when multiplied by the area covered by the roof gives an estimate the total surface area of the sloped roof itself.
Measure the rise of your 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.
Pitch is expressed as a ratio of the vertical rise to the horizontal span.
Calculate the roof pitch as the proportion of rise and run.
One medium to describe the roof pitch is in 12 runs.
Roof pitch refers to the slope which the rafter creates.
A 12 in 12 pitch is a steep 45 degree angle roof.
Calculate the rafter length substituting these values into the following formula.
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.
Let s say it is equal to 1 5 m.
Pitch rise run 1 5 6 25.
For example if the pitch of the roof is 6 then it is written as 6 12.
