How Hail Size Affects Different Roofing Materials

What to do if your experiencing Hail Damage

Different roofing materials react to hail based on the size of the ice and the strength of the material

How Hail Size Affects Different Roofing Materials

Hail size significantly impacts roofing materials differently, causing granule loss and bruising on standard asphalt at smaller diameters, while more rigid materials like tile and slate risk fracturing under larger impacts.
Understanding these damage mechanics helps homeowners determine whether a storm has caused purely cosmetic flaws or structural vulnerabilities. More information is available on the provider’s website.

At Oliwill Construction, we understand the rising costs cascading through several major sectors right now, leading people to feel that property improvements are lower on the priority list.

However, with flexible financing options, we can jump-start your project while comfortably spreading the financial impact.

Standard Asphalt Shingles

  • Small hail (1 inch or less): Pea- to marble-sized ice usually bounces off, but 1-inch quarter-sized stones can cause granule loss, soft bruises, and minor cracks.

  • Medium hail (1.5 to 2 inches): Ping-pong to egg-sized hail causes widespread bruising, fractured shingle mats, and leaks.

  • Large hail (2+ inches): Tennis-ball-sized ice completely tears and punctures standard shingles, requiring a full replacement.

Metal Roofing, Tile, and Slate (Concrete, Clay, and Natural Slate)

  • Small to medium hail (Under 1.5 to 2 inches): Dense concrete and slate easily deflect small ice balls. Clay is more brittle and can chip near 1.5 inches. 

  • Large hail (2+ inches): High-velocity or golf-ball-sized ice shatters concrete and clay tiles, popping corners and breaking water channels. Natural slate withstands up to 2 inches well, but cracks under bigger impacts. 

Wood Shakes and Shingles

  • Small hail (Under 1.5 inches): Older or dry wood can split under 1-inch hits, while sound wood handles pea-sized ice.

  • Medium to large hail (1.5+ inches): Splits, splinters, and punctures occur frequently, leading to immediate leaks.
