Ping pong-sized hail detected near Longmont, CO on June 21, 2026
Hail was detected at a radar-indicated point within the Longmont monitoring area. Actual impact can vary by neighborhood, so nearby homes should use this as a signal to check roofs, gutters, siding, and vehicles.
Damage assessment
The radar-confirmed strike placed the hail core approximately 18 miles west of downtown Longmont. Boulder County logged one report countywide that day. At 1.5 inches, architectural asphalt shingles are vulnerable to granule loss and bruising — damage that is often functional, not merely cosmetic, on roofs older than 10–12 years. Shingles installed within the last five years may show bruising without immediate leakage, but granule loss accelerates aging regardless of visible cracking.
On a home at Longmont's median value of $541,400, a 2% wind/hail deductible runs approximately $10,828. Typical repair cost for a 2,000 square foot roof in this market runs $6,814, with a range of $5,575–$8,052. Get a professional inspection before making any insurance decisions.
At these numbers, you're better off repairing out of pocket — the typical repair cost falls below your deductible. Filing a claim likely isn't worth it unless a full inspection reveals significantly more damage.

Contractor guidance
Local contractor data shows current backlogs of 2–4 weeks in the Longmont market. The intake assessment rates storm chaser risk here as moderate, with out-of-area contractors moving in after regional hail events to fill capacity gaps. Colorado does not require a state-level roofing license, but Colorado Senate Bill 38 (C.R.S. §§ 6-22-101 to 6-22-105) mandates a written contract on residential jobs over $1,000 with specific consumer protections. Before signing anything, verify current general liability and workers' compensation coverage, confirm a local business address, and ask whether the contractor holds Colorado Roofing Association membership or equivalent credentials.
Permits & building code
At 1.5 inches, repair rather than full replacement is the more likely outcome on roofs in good condition, though older shingles may cross the threshold into replacement territory after inspection. Boulder County requires a permit for roofing work — the contractor pulls it, cost runs $150–$350, and an inspection is required upon completion. Class 4 impact-resistant shingles qualify for a 10–20% discount with most Colorado insurers.
