Supplement Tool vs. writing manually vs. hiring a supplement company
The average roofing supplement is worth $1,200–$2,800. A supplement company would take $120–$420 of that. At $97/month, Supplement Tool pays for itself in the first job. At $297/month, one approval covers the month and puts $900+ back in your pocket.
Hail, wind, tornado, hurricane — the AI knows the specific line items and IRC codes for each type of storm damage.
Auto-references the exact Xactimate codes adjusters use: RFG STRT, RFG RIDGCAP, RFG DRIP, O&P, and more.
Every letter cites the relevant IRC sections (R905.2.8.5, R905.1.2, etc.) that adjusters can't dispute.
Tap the mic and describe the damage while you're still on the property. No typing, no notes to transcribe later.
Upload a damage photo and the AI identifies the affected areas, shingle type, and likely missed line items.
When an adjuster denies your supplement, fire back with a formal rebuttal citing policy obligations and standards.
