Why Hail History Matters for Homeowners

Insurance Claims

You have 1 year from the date of damage to file a claim in Texas. Knowing when storms hit your area helps determine if you have a valid claim window.

Risk Assessment

Understanding your area's hail risk helps you make informed decisions about roofing materials like Class 4 impact-resistant shingles.

Hidden Damage

Many homeowners don't realize they have hail damage. If your area was hit, your roof may have damage even if you don't see obvious signs.

Preparation

Historical patterns help predict future risk. Spring is peak season—ensure your roof is ready before storm season begins.

Hail Size Reference Guide

Not all hail causes significant roof damage. Here's what different hail sizes typically mean for your roof:

SizeDiameterComparisonTypical Damage
Pea0.25"PeaUsually no significant damage
Marble0.50"Marble/DimeMinor granule loss possible
Quarter1.00"QuarterDamage threshold - inspection recommended
Golf Ball1.75"Golf ballSignificant damage likely
Hen Egg2.00"Hen eggSevere damage expected
Tennis Ball2.50"Tennis ballSevere damage, possible penetration
Baseball2.75"BaseballDestructive, emergency repairs likely needed

Quarter-Size is the Threshold

Most roofing experts and insurance adjusters consider quarter-sized hail (1 inch) the threshold for potential significant damage. If your area experienced quarter-size or larger hail, a professional inspection is recommended even if you don't see obvious damage from the ground.
