Calculator Roof Pitch Formula

Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs.

Calculator roof pitch formula.

If you want to know how to find the pitch of a roof then start with a calculator. Use our roof pitch calculator to find the pitch of your roof. Next multiply the footprint of the roof by the multiplier below for your roof pitch to find the overall roof area. Even if you want to use a flat roof pitch calculator system you will be able to find one.

Often you express roof pitch as the ratio between the rise and the run in the form of x 12. It can be assessed in two ways either as the angle the rafter makes with the horizontal or the proportion between the rise and the run of the roof. The pitch is commonly defined as the ratio of rise over run in the form of x 12. The pitch of the roof is the rise over a 12 inch run.

It is often compared to slope but is not exactly the same. 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. 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. This is very useful information for many purposes especially for roof framing the slope sometimes called pitch is calibrated on speed squares.

The rise is the height of the roof and the run is the horizontal span as pictured above. Roof pitch or slope is a measure of vertical rise to horizontal run expressed in inches per foot. Roof pitch refers to the slope which the rafter creates. Roof pitch is simply the slopecreated by the rafter.

A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally. Roof pitch is often expressed as a ratio between rise and run in the form of x 12. 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. A a roof with a 6 rise for every 12 run has a 6 per foot or 6 in 12 pitch.

To accurately calculate the area of your roof you must first determine its slope or pitch. For example if a roof has a pitch of 4 12 then for every 12 inches the building extends horizontally it rises 4 inches. Roof pitch is the measurement of a roof s vertical rise divided by its horizontal run. Roof pitch formula image 1 12 to 12 12 roof pitch 7 12 pitch this is our pitch calculator which will convert pitch to angle or angle to pitch for half degree roof slope calculations.

For example a 4 12 pitch roof that is 100 square feet.
