Plain-Language Summary
Carrier and contractor estimates often differ in quantities, unit prices, waste, code items, and repairability assumptions. Comparing them carefully is more useful than focusing only on the bottom-line totals.
Action Checklist
- Align line items by trade and location
- Note missing code or detachment/reset items
- Compare waste factors and material assumptions
- Review depreciation and overhead/profit treatment
- Flag unsupported or unexplained differences
Illustrative Claim Examples
Hypothetical examples for education only. These are not case results.
- Contractor includes drip edge and starter course; carrier estimate omits them without explanation.
- Quantities for the same slope differ by a large margin between the two estimates.
What This Does Not Mean
- The higher estimate is not automatically correct
- Estimate differences do not prove bad faith
- We do not guarantee any supplement will be paid
