Roof pitch may be defined as the measure of the roof’s slant. It is one of the many significant parts of the roof.

Roof pitch is one of the most observable elements of a roof. It’s the measure of the steepness of a roof or its slope. Roof pitch is a ratio of the roof’s vertical rise to its horizontal span, or “run.”
