The Complete Hail Damage Supplement Checklist for Roofing Contractors

By Kyle Hamrick, Founder

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. On claims where the roof is already approved for full replacement, our closed files show a median recovery of about $4,000, with half landing between roughly $1,800 and $9,500.

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.
