A roof with a 6 rise for every 12 run has a 6 per foot or 6 in 12 pitch.
Run of the roof.
There are two main categories of roofing.
If you have a non standard roof such as an unequally pitched gable roof the span will be divided by the total number of sides.
For example a pitch 1 12 means that per every twelve yards.
Rise and run means that a 6 12 pitch roof has 6 of rise vertical for each foot of run horizontal.
The rise is the distance from the top of the roof to the bottom.
Roof pitch or slope is a measure of vertical rise to horizontal run expressed in inches per foot.
Angle the angle of a roof is the same as the roof s slope except instead of being.
A low slope roof is anywhere from 2 in 12 to 4 in 12.
We give the required roof slopes for different types of roofing materials and we illustrate several methods by which the slope or pitch of a roof is easily measured.
For example assume you have a standard roof and the span of the building is 26.
Roof pitch is often expressed as a ratio between rise and run in the form of x 12.
It can be assessed in two ways either as the angle the rafter makes with the horizontal or the proportion between the rise and the run of the roof.
The run is the horizontal distance of only a section of the roof.
Since a standard roof has just two sides the run is half of the span.

Roof pitch is simply the slope created by the rafter.
The run always remains constant at 12 inches.
Roof pitch refers to the amount of rise a roof has compared to the horizontal measurement of the roof called the run.
Roof pitch calculator results explained.
Roof pitch is indicated in inches rise of 12 inches run for instance a 3 in 12 pitch or 3 pitch or 3 12 pitch all represented that the roof rises 3 inches means for every 12 inches of its horizontal run.
The roof pitch is important in determining the appropriate installation method and how much roofing material will be needed.
Our roof rafter calculator tools are handy for calculating the number of rafters needed rafter length calculator lineal feet of rafter board feed in ridge and sub facia and the total board feet in the roof.
Anything more than 9 in 12 is considered steep.
Roof slope definitions measurement methods.
Here is an online rise and run calculator which helps to calculate pitch slope and angle with the help of rise and run values.
Slope the slope of a roof is represented as x 12 where x is the number of inches in rise for every 12 inches of run this is very useful information for many purposes especially for roof framing the slope sometimes called pitch is calibrated on speed squares.
This article defines different types or degrees of roof slope and explains how roof slope ptich angle or grade slope are measured expressed.
