Professional Degrees to Roof Pitch Converter

📐 How Pitch is Calculated

The roof pitch is calculated using the tangent trigonometric function:

Pitch (in/ft) = tan(angle in degrees) × 12

For example, a 26.57° angle gives: tan(26.57°) = 0.5, so 0.5 × 12 = 6 inches per foot (6/12 pitch).

⚠️ Important Considerations

• Flat roofs (0-2/12) require special waterproofing
• Steep roofs (≥6/12) require fall protection for workers
• Material suitability varies with pitch
• Local building codes may have specific requirements
• Always consult with a structural engineer for extreme pitches

📈 Industry Standards

Common roof pitch ranges:

• Flat: 0-2/12 (0°-9.46°)
• Low Slope: 2-4/12 (9.46°-18.43°)
• Conventional: 4-9/12 (18.43°-36.87°)
• Steep: 9-12/12 (36.87°-45°)
• Very Steep: >12/12 (>45°)
