Roof Measurement Documentation
Field procedure for ordering, verifying, and filing roof measurement reports — and reconciling them to carrier sketches for supplement-ready quantity arguments.
Claims Ninja Operations
Purpose
Produce measurement documentation that carriers accept as quantity authority — and reconciliation records that isolate square, ridge, and valley variances from carrier sketches.
When to use
New roofing claim before estimate review
Signal: Property address confirmed; carrier sketch pending or received
Carrier sketch squares differ from field observation
Signal: Material order feels short; accessory LF does not match site
Complex cut-up roof with unreliable aerial geometry
Signal: Multiple hips, valleys, crickets, or dormers on scope
Supplement quantity dispute on squares or linear feet
Signal: Adjuster cites carrier sketch as final quantity authority
Required documentation
Third-party measurement report (EagleView, Hover, or equivalent)
Premium or full report with facets, pitch, ridges, hips, valleys, eaves, rakes.
Report order date and property match confirmation
Verify correct structure on multi-building parcels.
Carrier sketch vs. report comparison table
Squares, ridges, hips, valleys, eaves, rakes — variance column highlighted.
Field verification notes for report anomalies
Required when report omits parapets, crickets, or recent additions.
Waste factor worksheet with cut-up factor noted
Document waste percentage rationale for complex roofs above macro default.
Step-by-step process
- 1
Order measurement report early
Field- Order within 24 hours of claim assignment — before carrier estimate arrives.
- Confirm correct address, structure, and report level (premium for supplements).
- Flag commercial, turret, or flat/low-slope sections needing field supplement.
- Store PDF in claim folder with order date in filename.
Early order beats carrier sketch to file; sets your quantity baseline.
- 2
Verify report against field observation
Field- Compare facet count and major geometry to ground and ladder observation.
- Check pitch table against gauge readings on steep planes.
- Note additions, sunrooms, or detached structures excluded from report.
- Document anomalies: parapets, crickets, unusual dormers not in aerial model.
- 3
Reconcile carrier sketch to report
Field- Build comparison table: carrier vs. report for squares and LF items.
- Highlight variances above 2% on squares or 5 LF on linear items.
- Photograph sketch page and report summary side by side for supplement.
- Escalate large variances to supplement coordinator before material order.
- 4
Document waste factor rationale
Field- Score cut-up factor: valleys, hips, dormers, turrets, designer shingle.
- Apply waste percentage per company standard (typically 10–18% on complex roofs).
- Record rationale in supplement file — not just a rounded number.
- Cross-check waste against shingle bundle count on delivery ticket.
- 5
Hand off to office for estimate revision
Field- Upload report, reconciliation table, and field notes to CRM.
- Flag planes needing steep/high modifiers from report pitch table.
- Confirm material order matches report quantities before production start.

Common mistakes
| Mistake | Impact | Correction |
|---|---|---|
| Using carrier sketch as material order basis without report | Short orders mid-job; accessory LF wrong; margin erodes. | Mandatory report order before production scheduling. |
| Ordering basic report without pitch and facet detail | Cannot support steep charges or waste arguments in supplement. | Premium report with pitch table and full linear dimensions. |
| Ignoring report-to-sketch variance under 5% as immaterial | 5% square gap removes thousands across shingles, felt, and labor. | Reconcile every variance; supplement quantity lines individually. |
| Default 10% waste on complex designer shingle roofs | Material shortage; weak supplement if waste challenged. | Document cut-up score; apply 15–18% where justified. |
Using carrier sketch as material order basis without report
Impact: Short orders mid-job; accessory LF wrong; margin erodes.
Correction: Mandatory report order before production scheduling.
Ordering basic report without pitch and facet detail
Impact: Cannot support steep charges or waste arguments in supplement.
Correction: Premium report with pitch table and full linear dimensions.
Ignoring report-to-sketch variance under 5% as immaterial
Impact: 5% square gap removes thousands across shingles, felt, and labor.
Correction: Reconcile every variance; supplement quantity lines individually.
Default 10% waste on complex designer shingle roofs
Impact: Material shortage; weak supplement if waste challenged.
Correction: Document cut-up score; apply 15–18% where justified.
Supplement opportunities
Carrier squares below measurement report
Reconciliation table + report summary PDF highlighted
Line item hint: Field shingles, underlayment, labor per corrected square
Ridge or hip LF understated in carrier sketch
Report ridge/hip table vs. sketch with photo of ridge line
Line item hint: Ridge cap, hip shingles, ridge vent LF
Valley LF missing or simplified in sketch
Report valley table + valley photos from roof
Line item hint: Valley metal, ice barrier in valley
Waste factor below job complexity
Cut-up factor worksheet + facet diagram from report
Line item hint: Waste percentage adjustment on shingle quantity

Quick answers related to this procedure.
Accurate measurements anchor defensible quantity arguments. Waste, pitch, and cut-up factors should reflect actual roof geometry — not generic defaults. We compare carrier quantities to field documentation and flag gaps worth pursuing.
Carriers expect photos of all slopes and damage, accurate measurements, line items aligned to how the roof was built, and code-related accessories where applicable. Supplement opportunities often hinge on drip edge, ice and water shield, ventilation, steep charges, and waste factors documented clearly.
