About Pitch and Slope
Roof pitch is typically expressed as a ratio like 6:12, meaning 6 inches of rise for every 12 inches of horizontal run. Slope percentage expresses the same relationship as a percentage, useful for grading and civil engineering applications.
Common Pitch Examples
- • 4:12 pitch = 33.3% slope
- • 6:12 pitch = 50% slope
- • 8:12 pitch = 66.7% slope
- • 12:12 pitch = 100% slope (45°)
