Understanding Metal Roofing Calculations

Metal roofing is measured in "squares" - one square equals 100 square feet of roof area. The actual number of panels needed depends on:

  • Roof dimensions (length × width)
  • Roof pitch (slope)
  • Panel size (width × length)
  • Waste factor (typically 10-15%)
