Either way let s see how you can calculate the slope of a roof without using a roof slope calculator.
How to find the slope of a roof math.
To do this simply convert the rise and run as a fraction to a decimal form eg.
Angle the angle of a roof is the same as the roof s slope except instead of being.
To find the gradient of other polynomials you will need to differentiate the function with respect.
Let us then try to put a slope of 4 as in the previous example on the coordinate system.
Learn how to write the slope formula from scratch and how to apply it to find the slope of a line from two points.
See below after the table for directions on how to convert any roof slope from one form to another even roof slopes not shown in the table.
Then put a run of 2.
If the form of the equation is y mx c then the slope or gradient is just m if the equation is not in this form try to rearrange the equation.
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 will be a right triangle.
Generally roof pitch is calculated from the same formula that describes a right triangle.

How to convert roof pitch to degrees.
Use the pythagorean theorem to solve.
The following table shows how the same common roof slopes can be expressed using rise in run ratios degrees and percentages.
To find the angle of a roof in degrees convert the pitch to a slope then convert to degrees by finding the arc tangent of the slope.
Access one of the rafters then take the measurement this way.
Measuring the slope from the rafters.
It s just a little math.
How to find the slope when we don t know the rise and the run.
You can put this solution on your website.
Write the roof slope as the ratio of rise over run or vertical distance over horizontal distance.
Degrees to roof pitch rise in run to see a table.
How to find slope from an equation.
If we graph the slope on the coordinate system we will be able to derive another useful formula.
Find the pitch of the roof shown.
Put a rise of 8 anywhere you wish.
The most precise way to find the roof s slope is by measuring it from the underside.
First convert the pitch to a slope.
Also see our page quick reference.
Rafter rise run from the pythagorean theorem.
Learn how to write the slope formula from scratch and how to apply it to find the slope of a line from two points.
Rise run rise run slope.
Let the slope the hypotenuse c.
Calculate the roof slope.
How to calculate roof pitch.
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.
The method for finding the slope from an equation will vary depending on the form of the equation in front of you.
