But not every hail event causes claim-worthy damage. Here's the honest breakdown of what hail size does what damage to gutters in Missouri and Kansas — and when it's worth filing an insurance claim. ## The short answer Hail **1 inch (quarter-sized) or larger** typically causes visible damage to aluminum gutters and downspouts. Below 1 inch, damage is rare. Above 1.5 inches (ping-pong ball), damage is highly likely to gutters, downspouts, roof shingles, AC units, and often siding. **NOAA's hail scale for reference:** · Pea: 1/4″ — rarely damages anything · Marble: 1/2″ — cosmetic only · Quarter: 1″ — **damages gutters and shingles begin showing damage** · Ping-pong: 1.5″ — full gutter denting, roof granule loss · Golf ball: 1.75″ — structural roof damage common · Tennis ball: 2.5″ — full roof + gutter replacement nearly always needed · Baseball: 2.75″ — gutters often torn loose, siding holed ## What hail damage looks like on KC gutters Gutters dent on the **front face** (the side facing out from the house) and on the **top edge** where the hail strikes most directly. Damage from above is harder to see from the ground — you need to get a ladder up and photograph the top of the gutter from the roof line. Common visible damage signs: - **Dents on the side of the gutter** — oval or round impressions, usually 3/8″ to 1″ across - **"Oil canning"** — long wavy distortion on the front face from multiple impacts - **Chipped or scraped paint** exposing bare aluminum - **Dings on downspouts** — usually visible on the front face - **Splash guards or end caps torn off** - **Bent or pulled-away sections** - **Asphalt shingle granules in the gutter** — sign the roof was hit hard enough to lose surface granules ## Why hail damage matters even if "the gutters still work" Insurance covers hail damage that's **functional OR cosmetic** in most KC-area policies. Even a gutter that still drains water properly can be claimed if it has visible dents that reduce its useful life. That's because: 1. **Paint compromise** — dented and chipped paint allows oxidation, shortening the gutter's lifespan from 30-40 yrs to 15-20 2. **Resale value** — visibly dented gutters reduce home value, often by more than the cost of replacement 3. **Structural integrity** — severely dented sections are weakened and can fail in future storms ## What about 5/8″ or 3/4″ hail? Smaller hail (3/4 inch and under, "marble" to "dime") **can** dent thinner aluminum gutters (especially older builder-grade .025 gauge) but usually doesn't trigger insurance claims. If your home was hit by 3/4″ hail and you don't see obvious dents, it's probably not worth filing. The deductible alone often exceeds the damage. However: **if you had previous undiagnosed damage** from a bigger storm, sometimes a smaller storm makes the older damage newly visible. Always worth a free contractor walk before assuming nothing happened. ## The Missouri/Kansas hail belt NOAA tracks hail events across the U.S., and KC is consistently in the "Hail Alley" top zone. The metro averages 3-5 damaging hail storms per year between March and June. April is the peak month. Major recent KC-area hail events: - **April 26, 2024:** Widespread 2-3″ hail across OP, Lee's Summit, Independence. Tens of millions in property damage. - **May 19, 2024:** Quarter-to-golf-ball hail in Johnson County and south KC, MO. - **May 11, 2023:** Tornado-bearing supercell, widespread hail and wind damage metro-wide. - **April 12, 2022:** Major spring hail event KC-wide. Cross-reference your storm date at the [NOAA Storm Events Database](https://www.ncdc.noaa.gov/stormevents/). Print the record for your insurance claim file. ## Document everything (right after the storm) Photos with timestamps + GPS metadata (which iPhone and Android embed automatically) are your single best claim evidence. **Take photos within 48 hours.** The longer you wait, the harder it is to prove the damage came from a specific storm. Walk the property with your phone. Photograph: 1. Gutters from the ground, then from a ladder (looking down at the top edge) 2. Downspouts from the front, top to bottom 3. AC unit fins (bent fins = strong hail indicator) 4. Car hoods and windshields (dates the storm) 5. Mailbox dents 6. Soffit, fascia, and siding 7. Any hail left on the ground — place a coin or ruler next to it for scale **Pro tip:** Take 3 photos of each damaged item — wide shot (whole side of house), medium shot (the panel/gutter), close-up (the actual dent with scale). Adjusters reject "blurry distant" photos all the time. ## When to call a contractor before insurance Almost always. A free contractor walk before you file means: - You know whether the damage exceeds your deductible (worth filing) or not - You have a written estimate to compare to the insurance settlement - You catch damage you couldn't see (top of gutter, back of house, valley areas) - The contractor can meet your adjuster on-site — catches "we don't see damage" disputes Use our free [Hail Damage Claim Helper](/tools/hail-damage-claim-helper/) to walk through every step.
