Calhan, CO hail storm on June 25, 2025 reached 1.25 inches

Calhan, CO saw a concluded hail storm on June 25, 2025. The peak confirmed hail size reached 1.25 inches.

What Happened

The first storm alert came at 1:30 PM MDT, with spotter-verified hail of 1.25 inches. A second alert followed at 6:37 PM MDT with 1 inch hail, also spotter-reported. The event produced two separate hail periods across the Calhan area.

The sequence points to a multi-zone hail event rather than a single brief burst. The earlier round delivered the larger stones. The later round added another round of damaging hail before the storm concluded.

Radar and spotter reports both supported the hail call. The 1.25-inch report set the peak size for the event. The second alert held at 1 inch, which kept the storm in the severe hail range through the evening cycle.

Damage Assessment

Hail in the 1 to 1.25 inch range can affect roofs, gutters, siding, vents, window screens, and soft metal trim. Asphalt shingles may show bruising or granule loss. Modified bitumen and older roof systems can show more visible impact marks. Vehicle panels often carry dents, especially on horizontal surfaces.

The larger 1.25-inch hail report raises the likelihood of inspection findings on exposed roofing and exterior finishes. The later 1-inch hail round can widen the field of claims if it crossed the same neighborhoods or adjacent blocks. On homes with older roof materials, the difference between 1 inch and 1.25 inches can change the scope of visible impact.

Commercial properties in the path should check flat roofs, rooftop equipment, condensate lines, and painted metal components. Warehouses, schools, and light industrial sites often show impacts first on HVAC covers, skylights, and perimeter trim. Fencing, signage, and outdoor fixtures may also show isolated hail marks.

What Contractors Should Know

Start with the roof surface and move to the perimeter. Inspect slopes that face the storm path, then check gutters, downspouts, ridge caps, and penetrations. Photograph impact marks, disturbed granules, and collateral damage on soft metals. If the property has recent repairs, document those areas separately so older wear does not get mixed into the storm loss.

Use the hail size range to set the inspection plan. The 1.25-inch peak supports a closer review of steep-slope roofing and vulnerable accessories. The 1-inch round later in the day supports a broader canvass, especially if the storm passed over more than one zone in Calhan. Multi-zone hail often produces uneven damage patterns from one block to the next.

Check vehicle lots, carports, and exterior storage areas before weathering changes the evidence. Look at skylights, turbine vents, soft metals, and roof-mounted equipment. On post-storm calls, note the time of each reported hail round and the material type in the field. That helps separate the earlier larger hail from the later 1-inch round.
