Hail Damage Roof Inspection: What a Certified Inspector Actually Looks For

A roof that's been hit by hail rarely looks damaged from the ground. Hail stones of 1" or larger can leave serious, insurance-claimable damage on an asphalt shingle roof while your front-yard view looks completely normal. That's why a proper on-the-roof inspection by a certified inspector is the only way to know what actually happened — and what your insurance company is willing to pay for.

This post walks through what a professional roof inspector actually does when they climb up after a hail storm, what they document, and how those findings translate into an approved insurance claim.

What counts as "claim-worthy" hail damage

Insurance adjusters generally treat any hail of 1.0" or larger as capable of damaging an asphalt shingle roof. That's roughly the size of a quarter. At 1.25" (half-dollar) and above, damage is almost always visible on close inspection. At 1.75" (golf ball) and up, the whole roof is usually totaled and the insurance payout covers a full replacement.

NOAA's radar-indicated hail data and NWS Local Storm Reports give inspectors a date, time, and estimated hail size for any event that hit your ZIP code. That data is the foundation of the claim — it proves the event happened and links it to a specific day on the calendar.

What a certified inspector checks (in order)

1. The roof field itself

The inspector walks a test square (usually 10x10 ft) on each roof slope and counts visible hail hits. They look for:

Bruising: dark, soft spots where the shingle's mat has been fractured. Not always visible — sometimes you have to feel for a soft "give" with a thumb.
Granule loss: exposed asphalt where the colored granules have been knocked off. Most common on the south and west slopes.
Shiny spots / circular impact marks: on older shingles, fresh granule loss makes the mat shine compared to surrounding granules.
Cracked or split shingles: hail hard enough to split the tab.
Exposed fiberglass mat: the white layer beneath granules is visible.

2. Soft metals

Hail dents on gutters, downspouts, vent caps, flashing, and rooftop HVAC condenser fins are the easiest "proof of hail" an adjuster will see. Inspectors photograph every dent. An adjuster who denies hail damage to shingles but sees obvious hail dents on a gutter is going to have a tough time making that denial stick.

3. Ridge caps, valleys, and flashing

Ridge cap shingles take the worst of any impact because they sit exposed at the peak. A damaged ridge is often the tipping point that converts a partial-roof claim into a full-replacement claim. Valleys (where two slopes meet) concentrate water and hail, so damage there is especially serious.

4. Pipe boots, skylights, and vents

Rubber pipe boots crack under hail impact. Skylights can develop hairline cracks that leak months later. Vent caps often show dents or split seams. These are itemized line items on the final claim.

5. Attic interior

The inspector looks at the underside of the roof deck from inside the attic — checking for fresh moisture, wet insulation, and active leaks that tie back to the storm event. Any interior water damage roughly doubles the claim value because drywall, paint, and insulation repairs get included.

Why documentation is the whole ball game

An approved insurance claim isn't about the damage existing — it's about the damage being documented to the insurer's satisfaction. A certified inspector produces:

Dated photographs of every damaged area (with measuring tools in frame)
A written damage summary referencing the specific storm event (NOAA-verified date)
Itemized repair scope with measurements and materials
Drone-imagery or aerial photos showing overall roof condition
Supporting weather data (NOAA SWDI radar, NWS alerts, NWS spotter reports)

This packet is what they hand to the insurance adjuster. Adjusters have a hard time denying a claim backed by twenty photographs and NOAA weather data. They have an easy time denying a claim backed by "there's damage, take my word for it."

Before you climb a ladder yourself — don't

Every year about 200 roofers die falling off residential roofs. Homeowner falls aren't tracked as carefully but they're a lot higher than that. An inspection by a professional with fall-arrest gear is free to you; a weekend you spend in a hospital is not. Stay on the ground and take photos of anything suspicious.

When to request an inspection

Any time you know your ZIP code was hit by hail of 1.0" or larger — whether you saw the storm or read about it after the fact — request a free inspection. Insurance claim windows are typically 12 months from the event date (some states less). Waiting costs you the claim.
