What is the smallest hail that would be expected to cause damage to a concrete tile in good condition?

1. 2 1/2"

2. 1"

3. 1 1/4"

4. 1 3/4"

The correct answer is: 1 3/4"

The damage threshold for concrete tiles generally begins at hailstones of a certain size. In the case of concrete tiles in good condition, hail measuring 1 3/4 inches is significant enough to potentially cause damage. This size is substantial enough to exert enough force upon impact, penetrating the surface and compromising the tile's structural integrity. Hail of this diameter can create cracks or dents, leading to leaks if the waterproofing layer is breached. It’s essential to note that while smaller hail might not cause immediate visible damage, larger stones, particularly starting from the 1 3/4 inch range, typically have the kinetic energy necessary to impact the material significantly. Understanding this helps in assessing the risk of hail damage to roofing materials, allowing reviewers to make informed decisions based on size and expected outcomes of damage in various conditions.
