Hail Exposure in New Orleans, LA

New Orleans, LA has recorded 2269 hail events within a 15-mile radius since 2015, based on NOAA NEXRAD radar data. With over 2269 events in a decade, New Orleans is considered a high-risk hail area.

The average hail size recorded near New Orleans is 0.95 inches. The largest single event recorded reached 3.5 inches. Hail of 1 inch or larger can bruise or crack asphalt shingles, and at 2 inches or larger a professional roof inspection is the normal next step after a storm. A recorded size is exposure, not a damage finding. Only a licensed roof inspection can determine whether a specific roof was damaged; coverage depends on the policy and carrier.

Hail season in Louisiana typically runs spring and early summer (April through July). During these months, atmospheric conditions create powerful convective thunderstorms capable of producing large hail. New Orleans residents should inspect their roofs after any storm and consider a professional inspection each spring.

Many standard homeowner's policies in Louisiana include hail under a "wind and hail" peril, but coverage and deductibles differ from one policy to the next. Claim deadlines and coverage rules vary by carrier and policy — confirm yours with your insurer or your state's insurance department. Document what you observe promptly. Even when nothing is obvious from the ground, a licensed roofer can check for impacts during an inspection — and that inspection, not a hail record, is what shows whether a roof was damaged.

Start by looking for obvious signs from the ground: dented gutters, dings on metal vents, chipped paint, or broken skylight glass. On the roof itself, hail damage appears as dark circular bruises or "spatter" marks on asphalt shingles where granules have been knocked away. Because roof damage is often subtle, many New Orleans homeowners miss it without a professional inspection. If HailScore shows events of 1 inch or larger near your property, scheduling a free inspection with a local contractor is strongly recommended.

A HailScore is a 0–100 risk index that measures historical hail activity near a specific property. The score is calculated from five factors derived from NOAA NEXRAD radar data: storm frequency (how many events), recency (recent storms score higher), hail size (larger hail = more damage potential), cumulative damage (repeated storms compound wear), and proximity (storms closer to your address weigh more). A score of 0–25 is Low, 26–50 is Moderate, 51–75 is High, and 76–100 is Very High — the same sacred bands used on the live report.

If your property is in New Orleans and nearby storms have produced hail of 1 inch or larger, a professional roof inspection is worth scheduling. New Orleans has recorded hail up to 3.5 inches nearby — large enough to bruise or crack asphalt shingles — but a recorded size is exposure, not a finding about your roof. Many roofing contractors in LA inspect at no charge and can document what they find; whether any of it is covered depends on your policy and carrier.

Hail damage repair costs in New Orleans typically range from $8,000–$25,000+ for full roof replacement. The final cost depends on roof size, pitch, material type (asphalt shingles vs. metal vs. tile), and the extent of damage a licensed inspection finds. Whether a confirmed repair is covered, and what deductible applies, depends on your policy and carrier. Getting more than one contractor estimate before deciding whether to file is a reasonable step.

HailScore uses data from the NOAA NEXRAD radar network (Next Generation Weather Radar), specifically the SWDI (Severe Weather Data Inventory) maintained by NCEI (National Centers for Environmental Information). For New Orleans, we analyze all radar-detected hail events within a 15-mile radius from 2015 to present, totaling over 2269 NOAA-linked events. Each record includes the storm's timestamp, geographic coordinates, and hail diameter in inches (radar-estimated or ground-reported).

HailScore data comes directly from NOAA's NEXRAD radar network, which is the same system used by the National Weather Service for official storm reporting. Radar sizes are a class rather than a measurement: MESH is tuned so that roughly 75% of measured hail comes in at or below the estimate, so read a size as accurate to about one tier. We use the 15-mile radius to capture hail that may have affected your specific neighborhood even if the storm center was nearby. For the most precise assessment of your individual property, a physical roof inspection by a licensed contractor is always recommended.
