Supplements are not a fight. They are an engineering reconciliation process between initial scope and field reality.

System Design: Build the File Like an Auditor Will Read It

Use one supplement package with five sections:

  1. Executive variance summary
  2. Line-item delta matrix
  3. Evidence index
  4. Permit/code support (where applicable)
  5. Updated estimate export and change log

The Delta Matrix Standard

Each variance row should include:

  • Carrier line item and amount
  • Requested line item and amount
  • Net delta
  • Evidence ID references
  • Technical rationale in one sentence

This removes ambiguity and keeps the discussion objective.

Common Colorado-Specific Gap Patterns

  • Permit-driven sequencing not reflected
  • Access complexity under-modeled
  • Accessory and collateral scope underrepresented
  • Documentation for statutory/contractual compliance missing

Evidence Hierarchy (Strongest to Weakest)

  1. Timestamped field photos with slope labels
  2. Permit and inspection artifacts
  3. Manufacturer/code references relevant to installed system
  4. Narrative-only assertions

The package should rely on levels 1-3, not level 4.

Timing Strategy

  • Submit supplement package quickly after initial scope receipt
  • Batch related deltas in one cycle where possible
  • Track carrier responses by line-item status

Status taxonomy

  • Approved
  • Partially approved
  • Need more evidence
  • Denied with reason code

Colorado law prohibits unreasonable delay/denial for first-party claims and provides remedies in defined circumstances. Keep supplement communication technical and factual; avoid unsupported legal posturing.

Homeowner Governance Checklist

  • Demand written rationale on denied deltas
  • Keep all versions of estimates and correspondence
  • Use one canonical “current scope” file at all times
  • Reconcile paid amounts to approved scope monthly until closeout
