Hail Damage Thresholds by Roof Type

Not all roofs are created equal. The type of material on your home determines how much damage hail can do:

Four small ice circles
Five quarter size ice circles
An ice and a ruler measuring 1.5 inches
Hail Size Damage to Asphalt Shingles Damage to Metal Roofing Damage to Tile Roofs
< 1" (Pea-Sized) Rare; may dislodge granules Usually none Minimal to none
1" - 1.25" (Quarter) Bruising, granule loss Dents possible Minor cracks
1.5" - 2" (Golf Ball) Cracks, punctures Dents, coating damage Cracks or broken tiles
> 2" (Tennis Ball+) Severe; likely replacement needed Heavy denting, structural issues Significant cracking and leaks

Wind, Roof Age, and Slope: Key Damage Factors

Hail size isn’t the only factor to consider. Three more variables play a big role:

  • Wind Speed: Strong winds drive hail with more force, causing deeper impacts, especially on roof edges. Gusty conditions can shift the trajectory of hailstones, resulting in uneven damage across different parts of the roof.
  • Roof Slope: Flatter roofs are more vulnerable to hail because they receive more direct hits. Steeper pitches tend to deflect hailstones, reducing impact severity—but not eliminating it.
  • Material Age: Roofs naturally degrade over time. Aging shingles may lose their protective granules and become brittle, making them much more susceptible to damage even from smaller hailstones.

Other Considerations:

  • Roofing Layers: If your roof has multiple layers of shingles, the top layer may show different damage patterns than the underlying ones.
  • Installation Quality: Poorly installed roofing systems are more likely to sustain heavy damage, as fasteners may fail or flashing may lift under impact.

Pro Tip: Even if your neighbor’s roof looks fine, yours might have taken more damage depending on slope, age, and material type. Always get a professional inspection to be sure.

Austin, TX: A High-Risk Zone for Hail

Austin is no stranger to hail. The region experiences frequent hail events, especially in spring and early summer. What makes Austin unique?

  • Variable Weather: Storms range from small pea-sized hail to destructive tennis-ball-sized chunks.
  • Roofing Variety: Homes in Austin feature a mix of materials, each responding differently to hail.
  • Urban vs. Suburban Impact: Densely populated neighborhoods may be better protected by surrounding structures and tree cover, while open areas see higher impact.
  • Frequent Storm Paths: Many hail-producing storms move directly through Travis and Williamson Counties multiple times per year.

If your zip code is in Travis or Williamson County, you’re statistically at risk.

FAQs About Hail Damage on Roofs

Look for bruised or missing shingles, dented flashing, granule loss, or exposed fiberglass. Professional inspectors use tools to identify less obvious issues like soft spots or water infiltration.

Yes. Quarter-sized (1") hail is the threshold where asphalt shingles can start to show bruising, cracking, or granule loss, especially if the shingles are older.

Typically no. Hail smaller than 1 inch rarely causes damage to roofing materials, though it may still affect soft metals like gutters or window screens.

Penny-sized hail (around 0.75") can cause very minor damage but is unlikely to affect roofing unless combined with high wind speeds or falling on an aging roof.
