# How To Figure Roof Pitch

### Calculate the roof pitch as the proportion of rise and run.

How to figure roof pitch. Use the following formula which also describes a right triangle. The pitch of your roof is 312. The run is the distance from the outside of the wall to the inside of the ridge.

Then in the attic place the end of the level against the bottom of a roof rafter and hold it perfectly level. It can also be written down as 25 or 14. In most cases a roof pitch is a ratio consisting of the rise and the run in the form of X12.

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 rise run 15 6 25. Rafter² rise² run² this formula is from the Pythagorean theorem.

Here is an online rise and run calculator which helps to calculate Pitch Slope and Angle with the help of rise and run values. The roof pitch is the slope that the rafters create on your roof. To find the pitch of your roof youll first need to set up a ladder tall enough to reach it.

However carpenters typically make use of diverse finders of roof pitch angles an example of that is being a rafter. To get x compute x12RISE over RUN1235442 Therefore the pitch of your roof is 4212. Roof Pitch Is Measured By Rise Run.

Roof pitch is the measurement of a roofs vertical rise divided by its horizontal run. For example a roof that rises 6 inches for every 12 inches of the horizontal run has a 6-in-12 pitch. This is very useful information for many purposes especially for roof framing - the slope sometimes called pitch is calibrated on speed squares.
