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
