Report an Error

Cost data should be accurate. If you've found a number that looks wrong, whether it's a labor rate that's off for your state, a material cost that doesn't match current pricing, or a formula that produces an unreasonable result, we want to know.

What to Include

  • Which calculator (e.g., "Roofing Cost Calculator")
  • Which state (e.g., "Texas")
  • What inputs you used (e.g., "2,000 sq ft, asphalt shingles, medium pitch")
  • What result you got (the low/mid/high range shown)
  • Why you believe it's wrong (a recent quote, published data, professional experience, etc.)
