Hail, Wind & Tornado Reports on May 4, 1998

Usually too small to cause hail damage to most sound asphalt roofs, siding, or gutters.

Below the NWS severe-hail threshold, but not always harmless. Repeated small hail can scuff surfaces, wear aging shingles, and loosen protective granules over time.

Below the NWS severe-hail threshold, but roof hail damage is still possible on older, brittle, poorly installed, or previously damaged shingles. May also mark screens, vents, gutters, and soft metal.

Still below the severe-hail threshold, but large enough to leave visible marks on soft metal and add wear to older or hail-weakened roof shingles.

The NWS severe-hail threshold. Quarter-size hail can bruise shingles, dent soft metal, and create roof hail damage worth checking.

More likely to dent gutters, vents, flashing, and siding. Hail damage risk rises quickly on older roofs or hail-weakened shingles.

Hail damage becomes more likely, including bruised shingles, granule loss, dented siding, and damaged roof vents.

Often causes roof hail damage, cracked shingles, dented gutters, damaged flashing, and siding impacts. A roof inspection is recommended.

Can crack or puncture shingles, expose mat, dent siding, and cause widespread hail damage across the roof and exterior.

Major hail damage is likely, including severe roof impacts, damaged siding, broken windows, and possible major roof repairs.

Can cause heavy hail damage across the roof, siding, gutters, windows, and exterior. Significant repairs are often needed.

Destructive hail damage. Can severely damage roofing materials, siding, windows, gutters, vents, vehicles, and exterior surfaces.

Catastrophic hail damage risk for roofs, windows, vehicles, siding, gutters, and exterior surfaces.
