What supplement companies charge (we don't)

Adjusters are trained to miss these line items.

On every single roofing claim, these items are routinely excluded or underpaid. Most contractors don't fight back because writing the letter takes too long.

Starter Strip

RFG STRT

Required by IRC R905.2.8.5 at all eaves and rakes

Hip & Ridge Cap

RFG RIDGCAP

Separate material and labor — not included in field shingles

Drip Edge

RFG DRIP

Required by IRC R905.2.8.5 — adjusters frequently omit it

Ice & Water Shield

RFG ICEWTR

Required in cold climates per IRC R905.1.2 — often excluded

Overhead & Profit

O&P

Standard 10% overhead + 10% profit — adjusters routinely deny it

Step Flashing

RFG FLASH

Required at all wall/roof intersections — frequently missed

Supplement Tool knows every one of these — and writes the letter that gets them approved.
