Fort Lupton, CO Hail Storm – August 2025

Fort Lupton, CO saw a concluded hail event on August 27, 2025 with peak verified hail at 1.25 inches. The storm produced three separate NWS alert areas across the afternoon and evening.

What Happened

The first alert area came in at 3:07 PM MDT with 1-inch hail detected through dual-polarization radar confidence. A second alert area followed at 6:23 PM MDT with a 1.25-inch hail estimate. A third alert area was issued at 6:43 PM MDT with another 1-inch hail estimate.

The sequence shows hail intensity building into the late afternoon, then tapering back to 1 inch in the final alert area. All three alerts were tied to dual-polarization radar, with the 1.25-inch reading marking the peak confirmed hail size for the event.

This was a multi-zone storm report covering the Fort Lupton metro area. The event is concluded.

Damage Assessment

Hail in the 1-inch to 1.25-inch range can leave concentrated impact marks on softer roofing surfaces and exposed exterior materials. Asphalt shingles can show bruising, granule loss, and edge scuffing. Metal trim, roof vents, gutters, and downspouts can show dents. Windows, skylights, and vehicle surfaces are also within the exposed field for this size range.

The 1.25-inch peak places the event in a range where roof checks should stay focused on slopes with direct hail exposure. South- and west-facing surfaces often collect the clearest field evidence in afternoon storms, especially where the storm core crossed quickly and dropped repeated impacts in a narrow corridor.

Exterior clues can be subtle from street level. Fresh granule wash in downspouts, small divots on soft metals, and uniform spotting on siding or deck railings are useful markers. On multi-zone events like this one, the first pass should stay tied to the timing and path of each alert area rather than a single point estimate.

What Contractors Should Know

Start with the 1.25-inch peak area and work outward along the reported hail path. Prioritize steep-slope roofing, roof accessories, vents, skylight frames, condensers, gutters, and window trim. In storms with repeated hail readings, the roof line often shows mixed severity from one exposure corridor to the next. Use that pattern to guide where to open inspection first.

Look for consistent impact signatures across adjacent surfaces. Check for collateral marks on fascia, soffit, siding, and HVAC housings near the same roof sections that picked up the heaviest exposure. For vehicle and exterior claims, document dents by panel and face angle, then pair that with the local timing of the alert areas. The 3:07 PM MDT, 6:23 PM MDT, and 6:43 PM MDT alerts give a clean timeline for field notes and customer conversations.

On multi-zone reports, crews should expect variation. One block can show scattered cosmetic damage while another sees clearer functional risk on softer roofing components. Keep inspection notes tied to the reported times, the observed impact pattern, and the materials present on site. That gives adjusters and property owners a cleaner record of what the storm actually did.
