Hail Damage Inspection
Why this matters
After hail storms, roofing contractors are in demand for damage assessment. Customers need expert inspection to determine if their roof was damaged + to support insurance claims. Understanding hail damage characteristics + the inspection process is essential for storm-related work.
What hail damage looks like
For asphalt shingles:
| Damage | Appearance |
|---|---|
| Functional damage | Granules removed; substrate exposed; failure of shingle |
| Cosmetic damage | Dents / pock marks; no functional issue |
| Bruise | Soft area; impact mark; sometimes spreads |
| Crack | Visible split in shingle |
| Loose granules | Customer reports granules in gutters |
Each has different significance.
Functional vs. cosmetic
The key distinction:
Functional damage:
- Reduces the shingle's life
- Compromises waterproofing
- Insurance typically covers
- Replacement justified
Cosmetic damage:
- Affects appearance only
- Doesn't reduce roof life
- Insurance may not cover
- Customer's choice on replacement
The inspector documents this difference.
Hail size + damage correlation
| Hail size | Typical damage |
|---|---|
| Pea-sized (0.25") | Minimal; some cosmetic |
| Marble-sized (0.5") | Cosmetic; sometimes functional |
| Quarter-sized (1") | Functional damage likely |
| Golf ball (1.5") | Significant functional |
| Tennis ball (2.5") | Major damage |
| Baseball (3+") | Catastrophic |
Larger hail = more damage.
Inspection procedure
Step 1: Customer interview
- When was the storm?
- Has a claim already been filed, and has an adjuster already been out?
- Customer's homeowner's insurance status
- Recent prior inspections
Step 2: Ground-level survey
- Walk around the property
- Look for visible damage
Step 3: Roof inspection
- Climb the roof carefully
- Inspect from corner to corner
- Document every concerning area
Step 4: Specific damage documentation
For each damage point:
- Photograph
- Note location (slope, row, etc.)
- Identify damage type (functional / cosmetic)
- Customer file note
Step 5: Comprehensive report
For the customer:
- Summary of findings
- Photos
- Recommendations
- Insurance support documentation
- Customer's expected next steps
A professional report supports the customer.
Common damage indicators
For inspection:
| Indicator | Significance |
|---|---|
| Visible granule loss | Functional damage |
| Substrate exposed (asphalt mat) | Functional |
| Cracked / split shingle | Functional |
| Bruise (visible darker spot) | Functional sometimes |
| Loose / displaced shingles | Storm damage |
| Granule accumulation in gutters | Recent damage indicator |
| Penetrations / soft spots | Functional |
| Damage pattern (oriented) | Hail direction |
Each is documented.
When to recommend replacement
For comprehensive damage:
- More than 20% of shingles damaged
- Multiple slopes affected
- Functional damage widespread
Customer's claim supports replacement.
When to recommend repair
For limited damage:
- Single section affected
- Limited shingle replacement
Repair option.
Insurance considerations
For storm claims:
- Customer should file with insurance promptly
- Adjuster visits
- Contractor's inspection supports
- Customer's coverage applied
Customer's adjuster determines.
Working with insurance adjusters
For roofing contractor:
- Be present at adjuster's visit OR
- Provide detailed report
- Customer's insurance representative
- Customer's interest supports
Cooperative relationship.
Hail-damage red flags
For inspections:
| Red flag | Significance |
|---|---|
| Customer claims damage from old storm | Verify dates; insurance typically requires recent |
| Customer claims damage on a new roof | Verify; sometimes manufacturing defect mistaken for hail |
| Pre-existing wear blamed on hail | Customer's documentation important |
| Pressure to "find damage" | Maintain professional integrity |
A reputable inspector reports honestly.
When the customer's claim is denied
For denied claims:
- Inspector's report supports
- Customer's appeal possible
- Independent inspection sometimes
- Customer's decision
Customer's options.
Customer expectations
For hail damage:
- Insurance covers some + customer pays deductible
- Repair vs. replacement based on damage extent
- Customer's home protection during work
- Customer's coordination
A trained customer supports the process.
Documentation standards
For hail inspection:
- Property address + identification
- Date of inspection
- Storm date (verified)
- Damage type (functional / cosmetic)
- Locations affected
- Photo documentation
- Recommendations
- Customer's signature
Comprehensive report.
Inspection timing
For storm response:
- Schedule promptly (customer + insurance timelines)
- Sometimes weeks-out demand
- Customer's insurance deadlines
- Customer's home protection
Some customers wait too long; insurance may decline.
Insurance claim timeline
Standard:
| Timeline | Action |
|---|---|
| Storm date | Damage occurs |
| 1-30 days | Customer notices |
| Customer files claim | Insurance |
| Adjuster visits | Inspection |
| Claim approved / denied | Customer's outcome |
| Repair / replacement scheduled | Customer's work |
| Project completed | Customer's home restored |
Multi-week process.
When the customer's claim is for total replacement
For comprehensive:
- Inspector confirms widespread damage
- Customer's coverage allows
- Customer's quote for new roof
- Customer's investment matched by insurance
A complete reroof.
When the customer's claim is for repair only
For limited damage:
- Inspector confirms limited
- Customer's quote for repair
- Customer's lower investment
A repair scope.
Cosmetic-only damage
For customer:
- Document
- Customer's insurance may decline
- Customer's options (out-of-pocket replacement, accept appearance)
- Customer's decision
A customer's choice.
Hidden damage
Sometimes:
- Granule loss elsewhere (not directly from hail)
- Wind damage from same storm
- Customer's complete claim
Document everything storm-related.
When the customer's roof is older
For aged roofs:
- Pre-existing wear vs. hail damage
- Document differences
- Customer's insurance specifics
- Customer's coverage limits
Older roofs may not be fully covered.
Customer education
For storm damage:
- "Your roof shows hail damage"
- "Functional vs. cosmetic distinction"
- "Insurance claim supported"
- "Customer's next steps"
A clear explanation.
Common pitfalls
- Pressure to claim damage that's not there
- Pre-existing wear blamed on hail
- Inadequate documentation
- Skipping the customer's adjuster meeting
- Customer's wrong expectations
Maintain integrity.
Multiple slope assessment
For each slope:
- Chalk the test square and photograph it with the slope direction identified (north, south, east, west). Adjusters expect per-slope test squares, and a report with one square for the whole roof gets kicked back
- Count the hits inside the square and record the number, not an impression. "North slope: 9 hits in the 10 by 10" is a finding; "north slope damaged" is an opinion
- Note the directional pattern. Hail comes in on a storm direction, so the windward slopes take the hits and the leeward slopes often show little. A roof with uniform damage on all four slopes usually is not hail
- Check the soft metals on that slope (vents, flashing, gutters, gutter apron) for the same directional pattern. Soft metal is the corroborating evidence for the shingle hits
- Photograph one close-up of a representative hit on each slope with a size reference in the frame
- Record slope pitch and access method, because that drives the repair scope and the labor line on the estimate
If one slope reaches the threshold and another does not, say so. A per-slope finding is what supports a partial-roof scope, and it is what protects you if the adjuster disagrees.
