10x10 Hail Test Square & Shingle Brittle Test Photo Playbook: Getting Full Roof Replacements Approved
Xactimate Codes: RFG 300, RFG 240, RFG FELT | Standard: Haag Engineering Hail/Wind Protocol & ASTM D3161 | Protected: +$11,800 per storm roof claim
Technical Answer Summary (Haag Engineering Hail/Wind Protocol & ASTM D3161)
When an insurance field adjuster inspects a wind- or hail-damaged asphalt shingle roof, the difference between a $700 spot-repair check and an $18,000 full roof replacement (Xactimate RFG 300 / RFG 240) comes down to two forensic proof sequences: the Haag 10x10-foot Hail Test Square (proving 8+ functional hail impacts per 100 SF across directional slopes) and the Repairability / Brittle Test (proving that lifting the overlapping shingle tab to 45 degrees to drive nails into a replacement shingle cracks the mat or causes granule crease failure). Capturing a clean top-down photo of each directional 10x10 test square, macro photos of bruised mat fractures, soft-metal collateral dings on box vents/gutters, and a 3-step before/during/after brittle repair test forces full slope and full roof approvals.
Adjuster Denial Trap: Field adjusters writing for "replace 12 wind-creased shingles ($650 below deductible)" instead of a full slope or full roof replacement because the contractor did not document a repairability brittle test or soft-metal collateral hits.
3-Column Xactimate Denial Trigger vs. Field Photo Evidence Matrix
| Adjuster Denial Reason / Scrub Trigger | Required Field Photo & Meter Evidence (IICRC Standard) | Copy-Paste Xactimate F9 Note Justification |
|---|---|---|
| Adjuster writes for "repair 8 wind-damaged shingles" on an aged, sun-baked architectural or 3-tab roof | 3-photo Brittle / Repairability Test sequence: (1) intact overlapping shingle above damaged tab, (2) gentle 45-degree lift to clear hammer/nailer head, (3) resulting fresh mat crease/granule fracture across the upper shingle | Existing shingles are non-repairable. Lifting the overlying course to the minimum 45° angle required to remove and fasten a replacement shingle causes immediate asphalt mat fracturing and granule loss across the upper course (see 3-step repairability photos), triggering cascading damage across the entire slope. |
| Carrier claims hail bruises are "blistering or mechanical foot traffic" | Soft-metal collateral damage photos (chalked hail dents on aluminum box vents, furnace cap, soft metal valley, and window screens) + macro photo of embedded granules inside the hail impact dimple | Directional soft-metal spatter and denting on roof vents, flashing, and downspouts (verified via chalk-rubbing photos) confirm high-energy hail impact. Shingle bruises exhibit crushed fiberglass mat with embedded granules—characteristic of hail per Haag Engineering standards, not blistering (which leaves an open crater with displaced granules). |
| Reviewer approves West and South slopes only, leaving North and East slopes unapproved | Labeled 10x10 Test Square photo on North, East, South, and West elevations + ridge cap and hip intersection continuity photo | Swirling storm winds produced functional hail impacts on all 4 directional elevations, and existing shingle dimensions/color lot are discontinued (verified via ITEL/shingle gauge photo), preventing partial slope tie-in. |
Copy-Paste Xactimate F9 Note Justification
F9 NOTE (FULL ROOF REPLACEMENT — RFG 300 / RFG 240): Forensic roof inspection conducted per Haag Engineering wind/hail protocols across all 4 directional elevations (N, E, S, W). Attached VouchCam packet includes: (1) Soft-metal collateral hail impact verification on roof appurtenances, (2) 10x10-ft Test Squares with numbered functional hail mat fractures, (3) Shingle gauge thickness & exposure verification, and (4) Repairability / Brittle Test proving overlying courses fracture when lifted 45° for nail installation. Partial spot repairs cannot be performed without damaging adjacent courses; full replacement is required.
Mandatory On-Site Field Photo Checklist
- Hard Gate #1: Soft-metal collateral hail hits (side-chalked aluminum box vents, turbine vents, gutter aprons, AC fins)
- Hard Gate #2: Full 10x10-ft Test Square on each directional slope (N, E, S, W) with slope ID and hit count chalked on roof
- Hard Gate #3: Macro close-up of numbered hail hits showing circular mat depression and embedded granules
- Hard Gate #4: 3-photo Repairability / Brittle Test sequence showing upper shingle fracturing during 45-degree nail-clearance lift
Frequently Asked Questions
How many hail hits inside a 10x10 test square are needed for an insurance roof replacement?
Most major property carriers treat 7 to 10+ functional hail hits per 10x10-foot test square (100 SF) on a slope—supported by soft-metal collateral damage on vents and flashings—as the threshold for full slope replacement rather than individual shingle patching.
Why is a 3-step photo sequence better than just photographing a creased shingle for a brittle test?
If you only photograph the shingle after it is already creased, desk adjusters often claim it was pre-existing wind damage or intentional over-bending. Taking a "Before lift (intact)", "During 45-degree nail clearance lift", and "After release (fresh crease)" sequence in VouchCam proves the shingle failed during normal repair manipulation.
