How to Calculate Roof Pitch? A Guide for Homeowners

What Is Roof Pitch and Why Do You Need to Calculate It?

Ever heard of the term roof pitch? Do you know why you need to calculate it? Identifying the pitch of your roof is vital when considering roof repairs, replacement, painting and solar installations.

Here in this guide, we will learn what roof pitch is and how to calculate it correctly:

What Is Roof Pitch?

Roof pitch is a measure of the steepness or slope of a roof, and is expressed as the ratio rise to run, or more simply, it tells you how high the roof rises over a certain distance. The most common way to find out the roof pitch is by using the “rise over run” format. For example, a roof pitch of 4:12 means that the roof rises by 4 inches for 12 inches horizontally.

Top 3 Methods to Measure Roof Pitch

Here are three common methods to calculate roof pitch: using a level, measuring from the ground, and using a roof pitch calculator.

Method 1: Using a Level

This method requires you to be on the roof; thus, it is necessary that you ensure your safety first. Here is how you can get started:

Place the level flat and horizontal on the roof's surface.
To measure the rise, use a tape and measure the vertical rise of the roof in inches from the end of the level to the roof's surface.
Since most levels are 12 inches long, calculating the run is pretty straightforward. However, if the level is not 12 inches, you will be required to take the actual horizontal measurement.
To calculate the pitch, calculate the rise per 12 inches of the horizontal run.
For example: if the roof rise is 6 and the roof run is 12, the roof pitch would be 6/12 that is equal to 0.5.

Method 2: Using a Roofing Calculator

Those who do not wish to perform the calculation by themselves can also use the digital approach and use online roofing pitch calculators. All you need to do is enter the roof rise and run, and leave the rest to the calculator. It will automatically calculate the value and present the result before you.

Method 3: Measuring from the Ground

If it is not feasible to climb the roofs to get the measurements, you can also measure the roof pitch from the ground using the method below:
