A speed square and level can be used to easily find the pitch of a roof.
How to calculate pitch of a roof.
In the united states a run of 12 inches 1 foot is used and pitch is measured as the rise of the roof over 12 inches.
A roof pitch multiplier also known as a roof pitch factor is a number that when multiplied by the area covered by a sloped roof gives the actual area of the roof.
The maths behind this number is that it is the square root of rise run 2 1.
Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs.
What is the roof pitch.
Roof pitch calculator results explained.
For example if your tape measure found a 6 inch vertical distance to the 12 inch mark on your level the slope is 6 12 or 6 in 12.
If you want to know how to find the pitch of a roof then start with a calculator.
Set the level on the edge of the speed square as shown below then place the heel of the speed square on a rafter or gable edge of the roof.
This will allow your project to carry the depth and detail in the roof that you wanted as well as make sure that it will maintain a sturdy and effective nature throughout.
The pitch of this roof is 4 8 12.
Even if you want to use a flat roof pitch calculator system you will be able to find one.
How roof pitch is calculated.
Roof pitch refers to the amount of rise a roof has compared to the horizontal measurement of the roof called the run.
It is often compared to slope but is not exactly the same.
Write the roof slope as the ratio of rise over run or vertical distance over horizontal distance.

The roof pitch calculator is a convenient online tool you can use to quickly assess the pitch of your roof to determine the length of rafters you need.
Calculate the roof slope.
The calculator above can handle much of this math.
Angle the angle of a roof is the same as the roof s slope except instead of being.
Measure with a speed square.
After finding out your roof pitch angles you can use the calculator to perform the calculations for you instead of doing them manually.
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.
The roof pitch is the slope of the rafter.
A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally.
Roof pitch is the measurement of a roof s vertical rise divided by its horizontal run.
To accurately calculate the area of your roof you must first determine its slope or pitch.
