Frequently Asked Questions About Delaware Hail

When was the last major hail storm in Delaware, OH?

The most recent quarter-size-or-larger hail storm recorded by NOAA within 25 miles of Delaware was on June 6, 2026. HailCheck refreshes from the NOAA Storm Events database daily, so newer events appear here as they are reported.

How often does it hail in Delaware?

How big does hail typically get in Delaware?

The largest documented hail near Delaware in the last five years was egg-sized. Most Delaware-area hail falls in the marble-to-quarter range, with destructive storms (egg-size or larger) appearing roughly once every few years.

Does my insurance cover hail damage in OH?

Most homeowners insurance policies in OH cover hail damage to roofs, siding, and gutters under the dwelling and other-structures coverage. Coverage typically requires the damage to be tied to a verifiable storm date — which is where the NOAA hail history above (and a HAAG-style test square validation) becomes important for the claim file.

How do I check hail history for a specific Delaware address?

Use the HailCheck address search to enter any street address in or near Delaware. HailCheck returns every NOAA hail event within a configurable radius, along with severity bands, dates, and storm narratives for Pro members.

What a HAAG-Style Test Square Validation Means in Delaware

If your property in or near Delaware took on hail during one of the storms above, the standard process for documenting damage is a 10×10 foot test square inspection. A HAAG-trained reviewer counts impact indicators — granule displacement, mat fractures, and bruising — within the marked square and produces a PASS or FAIL document for the claim file.

HailCheck offers a $99 photo-based HAAG-style test square validation. You submit photos from the field, our reviewer evaluates the impact indicators and cross-references the NOAA storm dates listed above, and a written PASS/FAIL determination is returned within one business day. We do not send anyone to the roof — the validation is built around the photos you submit.

Why Delaware's Location Matters for Hail

Delaware sits east of the traditional hail alley, where hail events are less frequent than the central plains but tend to be associated with strong squall lines and tropical systems. Local roof systems are less commonly hardened for hail, which can mean even moderate impacts produce claim-worthy damage.
