Let s assume it is equal to 6 m.
Roof rise and run calculator metric.
Rise and run means that a 6 12 pitch roof has 6 of rise vertical for each foot of run horizontal.
As aforementioned there is no standard pitch of a roof.
Here is an online rise and run calculator which helps to calculate pitch slope and angle with the help of rise and run values.
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.
Calculate the rafter length substituting these values into the following formula.
Let s say it is equal to 1 5 m.
Enter run the flat level length then click pitch angle or rise to select then enter other known dimension angle or pitch.
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.
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.

Enter the extension wall length into wall length and double the extension wall width then minus ridge thickness into the wall width entries.
Measure the run length it is the horizontal distance between the roof ridge and the wall of the building.
The run is the distance from the outside of the wall to the inside of the ridge.
Express roof pitch as the ratio of the amount of the vertical rise of a roof or rise over the corresponding horizontal distance or run you write the pitch assuming a run of 12 inches thus the ratio would describe how much a roof rises for each foot of the run.
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.
