How Supplement Writing Works

Updated May 2026·6 minute read

BizPilot doesn't generate generic supplement letters. It knows Xactimate line items, IRC code requirements, carrier-specific approval patterns, and word-for-word adjuster response scripts — the same knowledge a 20-year veteran carries.

What BizPilot knows

  • Xactimate line itemsExact codes, descriptions, and what each covers (RFG LBRD, RFG SLOP, RFG FELT, and hundreds more).
  • IRC code citationsInternational Residential Code sections that support your scope — specifically for flashing, ventilation, decking, and more.
  • Carrier-specific patternsWhich items carriers commonly deny, what language tends to get approvals, and how each carrier's appraisal process works.
  • Adjuster response scriptsWord-for-word scripts for the most common pushbacks — "we don't cover that," "it's pre-existing," "only like kind and quality."

How to describe your job for best results

The more specific you are, the more specific BizPilot's response will be. Include:

  • The carrier (State Farm, Allstate, USAA, Travelers, etc.)
  • The roof type (hip, gable, flat, complex)
  • What's being denied or undervalued (step flashing, O&P, code upgrades)
  • The adjuster's stated reason for denial if you have it
  • The scope size (sq footage, pitch, number of penetrations)
If you've set up your Business Context (Settings → Business Context), BizPilot already knows your typical carriers and job types. You don't have to repeat them every time.

Example: supplement for denied step flashing

Your prompt:

“State Farm is denying step flashing on a 2,800 sq ft hip roof in Texas. The adjuster says it's not storm damage. I need a supplement letter with IRC citations.”

BizPilot responds with:

  • → IRC R905.2.8.3 citation for step flashing requirements
  • → Xactimate line item RFG FLASH with unit pricing basis
  • → Argument that step flashing is always replaced at time of re-roof under proper scope
  • → Letter template addressing State Farm's common denial language

Using Quick Tasks

The sidebar Quick Tasks pre-configure common scenarios. Click one and you'll get a conversation pre-loaded with the right context:

  • Write supplement letterStructured prompt for a complete supplement with line items
  • Draft adjuster responseCounter a specific adjuster objection with evidence and script
  • Scope gap checklistWhat are the commonly missed line items for your roof type?
  • O&P justificationWhy overhead and profit applies, with supporting language

Following up on adjuster pushback

When the adjuster responds to your supplement and pushes back, paste their exact response into BizPilot:

“The adjuster responded: 'Step flashing is not included because the existing flashing is intact and not damaged by the covered peril.' Help me respond.”

BizPilot will generate a specific counter using the adjuster's own language back at them, with supporting code language and escalation options.

BizPilot provides expert guidance — it doesn't replace your professional judgment. Review all letters before sending, and consult a licensed PA for complex claims.
