SUPPLEMENT IT
OR EAT IT?

The break-even math

Filing a supplement costs you roughly 30 minutes of office time + the back-and-forth with the adjuster (call it another 30 minutes spread across the cycle). At a $50/hour blended office rate, that is $50 of labor cost per supplement.

For a supplement under $200, you are barely covering your office cost — even if it gets paid in full. Below $100, you are losing money chasing it. Above $400, the math becomes obvious.

Where the gray zone lives is $200–$400. The decision there depends on three other variables.

Variable 1: probability of getting paid

A code-driven item (drip edge, IWS, ridge cap upgrade) gets paid 90%+ of the time. A cosmetic upgrade with no code argument gets paid maybe 40%. Probability matters as much as dollar amount.

Variable 2: precedent for this carrier

If you have supplemented this carrier on this exact line item before and lost, the second supplement is unlikely to win. If you have won this exact item from this carrier before, the second one is almost guaranteed. Track outcomes per carrier per line type.

Variable 3: customer relationship

A supplement that delays the homeowner's final RCV check by three weeks can cost you a referral. If you can absorb $300 to keep the customer happy and stay on track for the next-door-neighbor lead, sometimes that math wins.

The simple decision rule

Always supplement: code-driven items + dollar amount > $300, regardless of customer impact. The carrier owes it; you collect it.

Almost always supplement: code-driven items > $200 with a clean photo trail.

Sometimes supplement: cosmetic items > $400 with strong evidence + a carrier you have won against before.

Rarely supplement: items < $200, or items > $200 with weak evidence and a carrier you typically lose against.

Never supplement: items < $100. The labor cost exceeds the dollar.

How to know before you start writing

Inside a real CRM, every supplement you have ever filed has an outcome — paid in full, paid partially, denied. Filter by carrier and line item type. Within a season, you build a personal database of "this carrier pays this kind of item at this rate." That database is the most valuable thing in your office.

The hidden third option: bulk supplements

On a multi-claim storm event, batch supplements per carrier rather than filing one at a time. The adjuster gets one big email instead of 12 small ones, your case gets attention because of volume, and the office cost-per-supplement drops dramatically. Modern roofing CRMs surface this with a "stuck supplements per carrier" filter.

The bottom line

Supplementing every missed line item is not the goal. Supplementing the right line items — high probability, code-driven, customer-tolerable — is. A 70% paid rate on the right supplements beats a 40% paid rate on every supplement, every time.
