🛠️ Key Xactimate Line Items & Claim Recovery Levers
Across 2026 storm swaths, initial field estimates miss an average of $5,200 in legitimate restoration line items:
- Starter Course & Drip Edge (RFG ASTR / RFG DRIP): Required by manufacturer wind warranties and IRC R905.2.8.5 building codes.
- Ice & Water Barrier (RFG IWS): Mandatory in valleys and 24 inches inside the exterior wall line in freeze/hail jurisdictions.
- HVAC Condenser Fin Combing & Surge Diagnostics (HVAC COMB): Often triggers the 3rd trade needed for 10% Overhead & 10% Profit (O&P).
- Emergency Power & Mitigation: Deploying EcoFlow DELTA Pro Ultra or Bluetti EP500Pro prevents secondary sump pump & food spoilage losses during grid blackouts.
