The Complete Hail Damage Supplement Checklist for Roofing Contractors

By Kyle Hamrick · March 22, 2026

A complete hail damage supplement requires the right documentation, the right line items, and the right submission process. Most claims that underperform fail at one of these three points — not because the coverage wasn't there.

Use this checklist on every hail job. It covers what to gather before you write, every line item category to verify, and what a proper submission looks like.

Documentation to Gather Before Supplementing

Carrier's initial estimate (PDF or Xactimate file)

Inspection photos — all slopes, all elevations, close-up impact shots

Aerial measurement report (EagleView or equivalent)

Storm data report showing hail size and event date

Manufacturer specs for proposed replacement shingles

Local building code requirements for drip edge, ice/water, ventilation

Any prior supplement correspondence with the carrier

Roofing Line Items to Check on Every Claim

Starter strip — should be starter product, not cut shingles

High-profile ridge cap — verify carrier priced architectural cap, not 3-tab

Ice and water shield — verify full perimeter per local code, not minimal coverage

Synthetic underlayment — if current code requires it, it's recoverable

Drip edge — required on replacement; frequently missing from carrier estimates

Step flashing — at all wall intersections, chimneys, and protrusions

Pipe jacks and boots — replacement warranted on most full re-roofs

Continuous ridge vent or off-ridge vents — verify replacement included

Steep slope charge — verify correct pitch bracket was used

Renailing sheathing — required by code in many jurisdictions on re-roof

OSB replacement — audit actual damaged percentage vs. carrier cap

Additional Items Often Missed

Satellite dish — detach and reset labor

Power vent — remove and replace, not just disconnect

Dumpster upgrade — if debris volume exceeds basic haul-off allowance

Gutter replacement — per-LF carrier pricing vs. current market rate

Fascia board damage — check at all guttered areas

Permit fees — required in nearly every jurisdiction, almost always missing

Overhead and profit — warranted on jobs requiring GC coordination

Cap flashing at chimney — often listed as repair when replacement is warranted

Supplement Submission Checklist

Supplement written in Xactimate with current pricing

All missed items supported by photos

Code requirements cited with jurisdiction reference when applicable

Carrier notified in writing of supplement submission

Follow-up scheduled within 3-5 business days

How Many Items Should Be on a Typical Hail Supplement?

On a full-replacement hail claim for an average residential roof, you should expect 8 to 15 supplemental items on top of the carrier's initial scope. Cumulative value typically runs $2,000 to $8,000+ per claim depending on roof size, pitch, and accessories.

If your supplement has 2-3 items, you're probably leaving money on the table. If you're not sure what you're missing, send us the carrier estimate and we'll show you.
