Ashtabula, OH Hail Storm – May 2025

Ashtabula, OH saw a concluded hail event on May 16, 2025, with peak verified hail reaching 1.25 inches. The storm produced six hail alerts through the early morning hours.

What Happened

The first hail alert came at 2:50 AM EDT with 1 inch hail tied to dual-polarization radar confidence. The storm intensified before dawn. Two later alerts at 4:31 AM EDT and 4:36 AM EDT verified 1.25 inch hail with radar and spotter support.

Additional alerts followed at 4:40 AM EDT, 5:17 AM EDT, and 5:23 AM EDT. Those later reports returned to 1 inch hail, with confidence levels split between dual-polarization radar and NWS warning information. The sequence shows a hail-producing storm that held together across several warning updates in the Ashtabula area.

The alert pattern points to a storm with recurring hail potential rather than a single brief burst. The verified 1.25 inch reports mark the peak size in this event.

Damage Assessment

Hail around 1 inch can mark shingles, dent gutters, and leave visible impact on soft metals, vents, and trim. Hail at 1.25 inches raises the chance of bruised shingles, cracked asphalt granules, broken roof attachments, and damage to window screens or exposed exterior fixtures.

In a multi-alert event like this, roof and siding checks should focus on the path where the storm maintained hail production through the early morning. Repeated hail reports can create scattered but concentrated damage across more than one neighborhood or block.

For exterior assessments, look for loss of granules on asphalt roofs, impact marks on metal surfaces, and dents on HVAC units, downspouts, and fascia. Vehicles parked outdoors during the event may also show visible pitting on horizontal surfaces and mirror housings.

What Contractors Should Know

This event supports a standard hail inspection workflow with emphasis on roof slopes, ridge caps, flashing, and soft metal components. The jump from 1 inch to 1.25 inches is enough to justify close inspection of north- and west-facing elevations, roof accessories, and any property with prior weathering.

Contractors should also review the timing of the alerts. The storm moved through in the early morning hours, which may affect which properties had vehicles outside, windows open, or exterior items exposed. That can widen the list of items worth documenting during a field visit.

Use the alert sequence to organize canvass zones and estimate roof exposure along the storm path. Properties that fall near the repeated 4:31 AM EDT to 5:23 AM EDT reports should receive priority for full exterior checks, including shingles, gutters, skylights, condensers, and siding panels.
