Damage Assessment

Hail at 1 inch can leave visible impact marks on vehicles, dent softer metal panels, and damage exposed roof accessories. The most common field checks in this size range include shingles, vents, skylights, gutters, and siding on the windward side of structures.

In rural mountain towns, 1-inch hail can also affect outbuildings, trailers, and agricultural equipment parked without cover. Contractors should expect the most obvious issues on south-facing and west-facing exposures when the storm moved through during daylight hours. The alert pattern supports a hail swath that warrants roof, gutter, and vehicle inspection across the warning area.

What Contractors Should Know

Start with a fast exterior scan. Check vehicle lots, metal trim, roof penetrations, and soft metals first. Look for fresh bruising on asphalt shingles, split seals around vents, and impact to ridge caps and pipe boots. On composition roofs, isolate the steeper slopes and the sides most exposed to the storm path.

Document every location with time, address, and hail size. In a multi-alert event like this one, the strongest field value often comes from matching the timing of visible impacts with the alert sequence. Separate older wear from fresh strike marks. On low-slope roofs, check drains, flashing, and membrane seams for puncture points. On steep-slope roofs, inspect for loss of granules, bruising, and lifted tabs.

If the site includes vehicles, HVAC units, or exterior fixtures, photograph panel dents, coil damage, and cracked plastic housings before any cleanup starts. In a town like Kremmling, scattered structures can sit outside the main core of impact while still falling inside the broader warning area. Prioritize the address list by roof age, roof type, and exposure to open sky.
