Pitch Of Roof Calculator

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.

Pitch of roof calculator.

We will explain to you how to determine the roof pitch step by step. The roof pitch is the slope of the rafter. A a roof with a 6 rise for every 12 run has a 6 per foot or 6 in 12 pitch. This roof pitch calculator is a handy tool that will help you quickly assess what is the pitch of your roof of what length of rafters you need for your construction works.

Use the diagrams on this page as a reference when inputting rise and run and while interpreting the calculated results. 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. The roof pitch calculator calculates slope pitch angle and rafter lengths based on input of rise m and run r. Roof pitch or slope is a measure of vertical rise to horizontal run expressed in inches per foot.

The pitch is commonly defined as the ratio of rise over run in the form of x 12. You can also use this roof slope calculator to recalculate the roof pitch from degrees to percents. The rise is the height of the roof and the run is the horizontal span as pictured above. Roof pitch is the measurement of a roof s vertical rise divided by its horizontal run.

After finding out your roof pitch angles you can use the calculator to perform the calculations for you instead of doing them manually.
