Genoa, CO Hail Storm – August 2025

Genoa, CO saw a concluded hailstorm on August 18, 2025, with verified hail up to 1.75 inches. The storm produced multiple rounds of hail across the afternoon and into early evening.

What Happened

The first hail alert came at 2:16 PM MDT with radar confidence for 1.5-inch hail. A stronger signal followed at 3:02 PM MDT, when dual-polarization radar supported a 1.75-inch hail estimate. Two more alerts came at 3:10 PM MDT and 3:50 PM MDT, both tied to 1-inch hail. The final alert arrived at 5:05 PM MDT with another 1-inch hail estimate.

The alert sequence shows a storm that maintained hail production for several hours. The largest verified hail size in the event was 1.75 inches.

Damage Assessment

Hail in the 1.5-inch to 1.75-inch range is large enough to drive calls for roof and exterior inspections across the warning area. In Genoa, that size can leave bruising on asphalt shingles, crack softer roof components, and mark painted siding, trim, vents, and window screens. Metal surfaces can show denting, especially on gutters, downspouts, and flashing.

The repeated 1-inch hail alerts later in the event point to a broader hail swath, not a single short burst. Properties in the path may show mixed impact levels. One roof can carry visible strikes on one slope and limited wear on another. Vehicles parked outdoors may show dents on horizontal panels, mirrors, and roof lines.

Contractors should expect the highest concentration of visible damage on exposed slopes, ridgelines, ridge caps, skylights, soft metal fixtures, and unprotected exterior equipment. Check for collateral issues around roof edges and penetrations. Look closely at debris fields, gutter deformation, and impact marks on siding at the upper wall line.

What Contractors Should Know

Field crews working Genoa after this storm should prioritize steep-slope roof checks, chimney flashings, vents, pipe boots, and skylights. The 1.75-inch peak size supports close inspection of aging asphalt shingles, where bruising and granule loss can be uneven across a property. Inspect north and west exposures as well as the first impact side of each structure.

Start with the warning area, then narrow to the addresses with the most direct hail exposure. Expect variation across short distances. Some structures may show clear strike patterns while nearby homes show lighter surface scuffing or isolated dents. That mix is common in multi-alert hail events with repeated radar-confirmed hail cores.

For contractors, the practical task is to separate cosmetic impact from functional damage and document both with location-specific photos. Pay attention to metal oxidation points, vent caps, downspout seams, and soft metals that reveal strikes more clearly than shingles. Vehicle lots, light poles, and exterior HVAC units may also provide useful field evidence when roof access is limited.
