## How to Calculate Roof Pitch
### Formula
**Pitch = Rise / Run** (typically expressed as X:12)
**Angle = arctan(Rise / Run)** in degrees
**Pitch Factor = sqrt(1 + (Rise/Run)²)**
Roof pitch is expressed as the number of inches of rise per 12 inches of horizontal run. For example, a 6/12 pitch rises 6 inches for every 12 inches of run. The pitch factor is used to convert footprint area to actual roof area.

Lösungsbeispiel
A roof with 6 inches of rise per 12 inches of run (6/12 pitch).
- Pitch = 6/12
- Angle = arctan(6/12) = arctan(0.5) = 26.6 degrees
- Pitch factor = sqrt(1 + 0.5²) = sqrt(1.25) = 1.1180
- Slope = 0.5 × 100 = 50%
