Frequently Asked Questions About Montgomery Hail

When was the last major hail storm in Montgomery, IL?

The most recent quarter-size-or-larger hail storm recorded by NOAA within 25 miles of Montgomery was on August 21, 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 Montgomery?

How big does hail typically get in Montgomery?

The largest documented hail near Montgomery in the last five years was baseball-sized or larger. Most Montgomery-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 IL?

Most homeowners insurance policies in IL 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 Montgomery address?

Use the HailCheck address search to enter any street address in or near Montgomery. 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 Montgomery

If your property in or near Montgomery 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 Montgomery's Location Matters for Hail

Montgomery 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.
