Roof Pitch Information
Common Roof Pitches
- • Flat Roof: 0-2:12 (0-9.5°)
- • Low Slope: 2-4:12 (9.5-18.4°)
- • Conventional: 4-6:12 (18.4-26.6°)
- • Steep: 6-9:12 (26.6-36.9°)
- • Very Steep: 9-12:12 (36.9-45°)
Roofing Considerations
- • Material Selection: Varies by pitch requirements
- • Water Shedding: Steeper pitches shed water better
- • Wind Resistance: Lower pitches resist wind better
- • Cost: Steeper pitches cost more to build
- • Maintenance: Steeper pitches are harder to maintain
