When is hail season in Colorado?+

Hail season in Colorado typically runs April through August, with peak activity in May and June. During these months, atmospheric conditions create powerful convective thunderstorms capable of producing large hail. Fort Collins residents should inspect their roofs after any storm and consider a professional inspection each spring.

Does insurance cover hail damage in Colorado?+

Most policies require you to file a claim within 1–2 years of the storm date, though this varies by insurer and state law. It's important to document damage promptly. Even if damage isn't visually obvious from the ground, a licensed roofer can identify hail impacts during a free inspection.

How do I check my roof for hail damage in Fort Collins?+

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 Fort Collins 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.

What is a HailScore and how is it calculated?+

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 0–30 is low risk, 31–60 is moderate, 61–80 is significant, and 81–100 indicates a high-impact hail history.

Should I get a roof inspection in Fort Collins?+

If your property is in Fort Collins and any nearby storms have produced hail of 1 inch or larger, a free professional roof inspection is highly recommended. Given that Fort Collins has recorded hail up to 4 inches, there is a real probability of roof damage that insurance may cover. Many roofing contractors in CO offer free inspections and can document damage for your insurance claim at no upfront cost.

How much does hail damage roof repair cost in Fort Collins?+

Hail damage repair costs in Fort Collins 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. In most cases, if hail damage is confirmed, your homeowner's insurance will cover the cost of repair or replacement minus your deductible. Getting multiple contractor estimates before filing a claim is a smart approach.

What NOAA data does HailScore use for Fort Collins?+

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 Fort Collins, we analyze all radar-detected hail events within a 15-mile radius from 2015 to 2025, totaling over 2289 verified events. Each record includes the storm's timestamp, geographic coordinates, and measured hail diameter in inches.

How accurate is HailScore data for Fort Collins?+

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 detection has a small margin of error. Hail size estimates can vary by ±0.25 inch compared to ground truth measurements. 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.
