Roof slope as rise in run x in 12 1 0 209 in 12.
Roof rise over run formula.
This will give you the rise over run or pitch.
The horizontal change in distance or the horizontal distance covered by an un supported rafter or truss.

This page offers you the rise and run formula to find the pitch slope angle of the roof of a building.
13 2 770 in 12.
Slope measures the angle of change in elevation which can be obtained by dividing rise by run and multiply the result with 100.
In roof pitch calculator pitch value can be obtained by dividing n by 12 and divide s by the answer.
Which is the same as saying a 45 degree slope a 12 in 12 slope or the roof will rise 12 for every 12 of horizontal run.
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.

We used this detail to calibrate our folding carpenter s rule scale for reading roof slope from the ground.
A 3 in 12 roof rises 3 for every 12 of run.
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.

Here is an online rise and run calculator which helps to calculate pitch slope and angle with the help of rise and run values.
For example if you measure 4 inches the pitch of your roof is 4 12.
Why is the roof slope 25.
3 of rise per 12 of run is the same as 1 of rise per 4 of run or 1 4 25.
The diagram shown below illustrates this.
Convert roof slope from degrees to rise in run.

The simplest way to look at the slope is.
4 0 839 in 12.
A a roof with a 6 rise for every 12 run has a 6 per foot or 6 in 12 pitch.
9 1 901 in 12.
This is very useful information for many purposes especially for roof framing the slope sometimes called pitch is calibrated on speed squares.
Details of that procedure are at roof measurements.
14 2 991 in 12.
Roof pitch or slope is a measure of vertical rise to horizontal run expressed in inches per foot.
The rise is the distance from the top of the roof to the bottom.
Finally you can find the roof pitch in the form of x 12.
The pitch value can be obtained by dividing n by 12 and divide s by the answer.
7 1 473 in 12.
That s the same as a 14 degree slope or a 25 slope.

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.

Recalculate this value into an angle.

Roof angle in degrees.
The run is the distance from the outside of the wall to the inside of the ridge.

Calculate the roof pitch as the proportion of rise and run.
