Roof Hail Damage vs Age Damage: How to Tell the Difference

When your roof has problems, knowing whether it's storm damage or normal wear matters—especially for insurance claims. Hail damage is typically covered by insurance, while age-related deterioration is not. Here's how to tell the difference.

Understanding Asphalt Shingle Construction

To identify damage types, you need to understand shingle construction:

• Fiberglass mat: The core layer providing structure
• Asphalt coating: Waterproofing layer
• Granules: Ceramic-coated rock that protects from UV and impacts

Different types of damage affect these layers differently.

Signs of Hail Damage

Impact Marks (Bruises)

Hail creates distinctive impact damage:

• Random pattern across the roof (not in rows or consistent locations)
• Round or irregular indentations
• Soft or spongy spots when pressed
• May or may not have visible granule loss at impact site
• Often more numerous on roof slopes facing the storm

Granule Displacement

Hail knocks granules loose:

• Bare spots with exposed asphalt (dark colored)
• Granules knocked loose but not worn away
• Fresh-looking granule loss (shiny asphalt underneath)
• Random pattern of granule loss

Cracking

Severe hail can crack shingles:

• Star-shaped or circular cracks at impact points
• Cracks radiating from impact center
• Fresh breaks with sharp edges

Soft Metal Damage

Look for hail damage on:

• Vent caps and pipe collars
• Gutters and downspouts
• Flashing
• AC units
• Window screens

Damage to these items often confirms hail occurred.

Signs of Age-Related Deterioration

Granule Loss from Weathering

Normal aging shows different patterns:

• Gradual, uniform granule loss across surfaces
• More severe on south-facing slopes (more sun exposure)
• Consistent pattern, not random spots
• Granules in gutters accumulate over time
• Exposed asphalt looks dull and weathered, not fresh

Curling and Cupping

Age causes shingles to deform:

• Edges curl upward (curling)
• Centers cup upward (cupping)
• Uniform across similar-age shingles
• Caused by moisture loss in asphalt layer

Cracking from Age

Age-related cracking looks different:

• Long, straight cracks following shingle edges
• Alligatoring pattern (looks like dried mud)
• Cracks follow stress lines, not random impacts
• Brittle, dried-out appearance

Blistering

Manufacturing defects or age cause blisters:

• Bubble-like raised areas
• Can be open (exposed) or closed
• Not caused by impacts—moisture trapped during manufacturing
• Often uniform across batch of shingles

Key Differences Summary

Why This Matters for Insurance

Insurance covers:

• Sudden, accidental damage (storms, hail, wind)
• Direct physical loss

Insurance does NOT cover:

• Normal wear and tear
• Gradual deterioration
• Maintenance issues
• Pre-existing damage

Mixed Damage Situations

Often, roofs have both types of damage:

• An aging roof that also got hit by hail
• Hail damage from different storms over years
• Age-related issues accelerated by storm damage

Insurance should cover the storm damage portion. However, they may depreciate payment based on roof age or condition.

When to Get a Professional Inspection

Don't try to diagnose damage yourself if:

• You're unsure what caused the damage
• You need to file an insurance claim
• A storm recently hit your area
• You're considering buying a property

HAAG-certified inspectors are trained to identify damage types accurately. Their assessments carry weight with insurance companies.

What Adjusters Look For

Insurance adjusters use specific criteria:

• Test squares: They examine multiple 10x10 areas
• Damage count: Minimum hits per square to qualify for replacement
• Collateral damage: Looking for other hail indicators
• Roof age: Comparing damage patterns to expected wear
• Storm history: Checking if reported storms actually occurred
