Hail Reports in Dubuque, Iowa — Last 90 Days

Dubuque is not hail alley, but it is not exempt either — the area averages about 5 hail-producing storms a year. When a cell does track over the county, the reports below tell you the date, the stone size, and how close it came.

Dubuque's Storm-Climate Context

Dubuque sits on the Mississippi River bluffs under a humid continental climate that delivers one of Iowa's heaviest snow burdens: an average of 42.5 inches annually across roughly 29 snowy days. Temperature swings are extreme -- the recorded high is 110 F in July and the recorded low is -32 F in January -- creating intense freeze-thaw cycling that stresses shingles, flashings, and gutters through repeated expansion and contraction. Spring and summer bring severe thunderstorm risk from the Upper Midwest storm track, adding hail granule loss and wind-uplift exposure to roofs already weakened by winter ice dams. The combination of heavy snow load and wide temperature range makes Dubuque one of the more demanding roofing environments in Iowa.

Dubuque, with 59,667 residents per the 2020 census, has diversified well beyond its industrial roots into healthcare, publishing, and tourism while retaining significant manufacturing. The largest single employer is John Deere with 2,600 workers, followed by the Dubuque Community School District (1,957), MercyOne Dubuque Medical Center (1,410), Medical Associates (1,061), and Finley Hospital (975). A stable, employment-anchored population with a mix of older Mississippi River-town housing and newer suburban development keeps both re-roofing and new-construction roofing demand steady for contractors in this northeast Iowa market.

How Severe Was It? The NWS Yardstick, Applied to Dubuque's Reports

The National Weather Service calls hail severe at 1″ (quarter size) and significant at 2″ (hen-egg size). Scoring the 1 Dubuque-area report (filed in Dubuque County) against that scale: 1 of them met the severe 1″+ criterion — the size at which asphalt shingles start taking granule loss and bruising that shows up as leaks a season later. Damage at these sizes is rarely visible from the ground but is typically covered by homeowners insurance when documented promptly.

What to Do If Your Roof Was in the Hail Path

1. Do a ground-level walk-around. Hail is rare enough around Dubuque that most homeowners never think to check — look for granules collecting at downspouts, dented gutters or screens, and battered plants after the July 2, 2026 report above. Stay off the roof itself.
2. Photograph anything suspicious with dates. Even minor-looking marks matter later: this NOAA log plus dated photos connect the damage to a covered storm event instead of "gradual wear", which insurers exclude.
3. Book a free inspection rather than guessing. Bruised shingles and granule loss are invisible from the ground; a written scope from a local roofer settles whether there is a claim at all.
4. Only involve the insurer once you know the scope. If the inspection finds nothing, you have lost nothing; if it finds damage, file within your policy's window while the event date is easy to prove.
5. Bring the written scope to the adjuster. Full walkthrough in the roof insurance claim guide.
