Roof Pitch Triangle Calculator

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

Roof pitch triangle calculator.

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. Select inches to enter decimal inches or millimeters for metric. If you know the angle of the roof in degrees you can find the roof pitch by converting the angle in degrees to a slope then finding the rise by multiplying the slope by 12. A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally.

Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs. Roof pitch calculator results explained 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. First find the slope by finding the tangent of the degrees eg. The pitch is commonly defined as the ratio of rise over run in the form of x 12.

If a roof or ramp rises 4 in a length of 12 the pitch is 4 in 12 which is 18 43 or 33 33 grade enter base length to calculate rise and diagonal for current pitch angle. Even if you want to use a flat roof pitch calculator system you will be able to find one. The roof pitch is the slope of the rafter. The picture below shows the pitch of a 7 12 roof slope meaning that for 12 of horizontal measurement roof run the vertical measurement roof rise is.

You can also use this roof slope calculator to recalculate the roof pitch from degrees to percents. For example if a roof has a pitch of 4 12 then for every 12 inches the building extends horizontally it rises 4 inches. We will explain to you how to determine the roof pitch step by step. 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.

This is very useful information for many purposes especially for roof framing the slope sometimes called pitch is calibrated on speed squares. To accurately calculate the area of your roof you must first determine its slope or pitch.

If you want to know how to find the pitch of a roof then start with a calculator.

The rise is the height of the roof and the run is the horizontal span as pictured above.
