Understanding Roofing Calculations
Accurate roofing calculations are crucial for any roofing project. Here's what you need to know:
Key Terms
- Square: A roofing square equals 100 square feet of roof area
- Bundle: Typically 3 bundles make up one square of shingles
- Pitch: The slope of your roof expressed as rise over run (e.g., 4/12)
Important Considerations
- Always add 10-15% extra material for waste and cuts
- Consider additional materials like underlayment and flashing
- Steep pitches require more materials due to increased surface area
- Local building codes may affect material requirements
