Colorado is one of the top five states for hail frequency in the country. The Denver–Fort Collins corridor — which includes Longmont — sits squarely in what insurance industry researchers call the “Hail Alley.” If you own a home in Longmont, Boulder County, or anywhere along the Northern Front Range, understanding the hail season timeline isn’t optional — it’s a financial survival skill.
When Does Colorado Hail Season Run?
Colorado hail season runs roughly March through September, with peak activity in May, June, and July. The most severe storms typically occur in the late afternoon and early evening when atmospheric instability peaks after daytime heating. The Front Range’s unique geography — where cold Rocky Mountain air collides with warm plains air — makes it a natural incubator for severe thunderstorm development.
How Bad Can Colorado Hail Get?
Colorado regularly produces hailstones 1–3 inches in diameter — the size of golf balls and beyond. Hailstones larger than one inch can:
- Crack asphalt shingles and create functional damage (even without visible holes)
- Dent and puncture aluminum gutters and downspouts
- Crack vinyl siding and break fiber cement siding
- Break window screens and seal window seals
- Dent soft metal on HVAC units, vents, and plumbing stacks
The Most Important Thing Longmont Homeowners Get Wrong
Most homeowners call their insurance company first. This is the wrong order of operations.
When you call your insurer first, they send an adjuster with a mission to close your claim quickly. That adjuster inspects your roof, checks a few boxes, and writes a check — often missing siding damage, window damage, soft metal damage, and secondary roof damage that requires expertise to identify.
The right order:
- Call Josh Brooks Construction and Renovation Inc. for a free professional inspection (720-828-7997)
- We document every impact point across your entire home exterior
- We help you file your claim with complete documentation
- We attend the adjuster inspection with you
- We supplement the claim if anything was missed
Colorado’s 2-Year Claim Window
Under Colorado Revised Statute 10-4-110.8, homeowners have two years from the date of the storm to file a property damage insurance claim. This sounds like plenty of time — but many homeowners don’t realize they have storm damage until a year or more has passed. By then, the claim window is narrowing fast and documentation becomes harder to produce.

NAR / NARI
“Colorado’s 2025 hail season produced 151 reports of hail over 2 inches in diameter — 2nd most in the nation. If your roof is more than 15 years old, it’s worth getting inspected before the next storm hits. I’ve been doing free inspections since 2014.”
