Damage Assessment

One-inch hail is enough to produce scattered exterior damage. Contractors should expect impacts to soft metals, vents, AC fins, screens, gutters, and roof accessories. Vehicles parked outdoors may also show denting, especially on horizontal panels and exposed trim.

Roof outcomes depend on surface age and material. Asphalt shingles can show bruising, granule loss, and displaced tabs. Metal roofing may show cosmetic strikes or punctures at weak points. On older systems, field inspection should focus on ridge caps, edge metal, pipe boots, skylights, and other transitions where impact marks are easier to miss from the ground.

Interior leaks are not implied by hail size alone. They are more likely where the roof already has wear, missing sealant, or prior storm damage. Crews should document each elevation separately and note any matching impact pattern on siding, windows, and exposed equipment.

What Contractors Should Know

Start with a roof-to-ground walkaround before climbing. Check downspouts, gutters, condenser coils, window screens, and fence caps for impact marks. On multifamily or commercial sites, review the windward elevations and any flat roof sections with exposed mechanicals. Keep notes on slope, material type, and whether the impacts are isolated or widespread.

Use the timing window to organize dispatch and scope. The first radar-confirmed alert came at 3:23 PM MDT and the second at 4:11 PM MDT. If you are matching claims to the storm path, separate cosmetic loss from functional damage and photograph each affected area with a clear time and address record. That keeps the file aligned with the actual hail timing in White Sulphur Springs.
