Roof Run Calculator
Understanding roof geometry is essential for any roofing project, and one of the most important components is the roof run. The run represents the horizontal distance used to calculate slope and rafter length. Our Roof Run Calculator helps you quickly determine this measurement and related values for precise planning.
This tool is ideal for builders, engineers, and DIY enthusiasts working on roofing projects.
How the Roof Run Calculator Works
The calculator determines the horizontal run based on roof span and pitch.
Required Inputs
- Total roof span
- Roof pitch
- Rise (optional if calculating run)
Calculation Logic
- Run = Span ÷ 2
- Pitch = Rise ÷ Run
Outputs You Get
- Roof run
- Roof pitch
- Rise (if not provided)
- Slope angle
Practical Example
- Span: 20 ft
Calculation:
- Run = 10 ft
If rise is 5 ft:
- Pitch = 5/10 = 6/12
Benefits
1. Accurate Measurements
Essential for roofing layout.
2. Simplified Calculations
No manual math required.
3. Time Saving
Instant results.
4. Versatile Use
Useful for multiple roof types.
