Understanding Roof Pitch

Pitch compares the roof s span to the rise while slope compares rise and run.

Understanding roof pitch.

The term pitch and slope are often used interchangeably which is incorrect. Mathematically the pitch of a roof is different calculation than roof slope. They do not mean the same thing. For example a roof that rises 6 inches for every 12 inches of horizontal run has a 6 in 12 pitch.

A roof that ascents six inches each twelve level inches is depicted as a 6 and 12 roof. Simply put roof pitch is the measurement of the angle or the steepness of your roof. The pitch of your roof is determined by the measurement of the vertical rise by the horizontal run. The rise is the height of the roof from the base to the top.

How to measure roof pitch. This implies a rooftop that is 4 inches higher than it was 12 creeps back assessing on a flat plane is a four and twelve rooftop. Roof pitch is the rise of the roof over the run of the roof. The angle or pitch of a roof is calculated by the number of inches it rises vertically for every 12 inches it extends horizontally.

You ll often hear experts express pitch as x over y. To calculate pitch you simply divide rise by span and display your result as a fraction. For example given a roof with a rise of 4 feet and a span of 24 feet the pitch is 1 to 6 pitch which can be expressed as the fraction of 1 6. Roof pitch is indicated by the measure of vertical ascent they ensure for each twelve creeps of horizontal estimation.
