Understanding Roof Pitch

They do not mean the same thing.

Understanding roof pitch.

The term pitch and slope are often used interchangeably which is incorrect. You ll often hear experts express pitch as x over y. Simply put roof pitch is the measurement of the angle or the steepness of your 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.

To calculate pitch you simply divide rise by span and display your result as a fraction. The pitch of your roof is determined by the measurement of the vertical rise by the horizontal run. For example a roof that rises 6 inches for every 12 inches of horizontal run has a 6 in 12 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.

A 12 to 24 pitch is expressed as 1 2. Because it is one of the many key elements that determine the safety of the roof over your head there is a very good reason to understand the purpose of roof pitch. Pitch compares the roof s span to the rise while slope compares rise and run. For example if a roof is 8 feet high and spreads out from the center covering 12 feet in each direction the rise over the run would be 8 12.

Roof pitch is the rise of the roof over the run of the roof. Roof pitch is indicated by the measure of vertical ascent they ensure for each twelve creeps of horizontal estimation. Mathematically the pitch of a roof is different calculation than roof slope. A roof that ascents six inches each twelve level inches is depicted as a 6 and 12 roof.
