Protocol Input

Systematic evidence capture, collateral mapping, and code-aligned material verification for insurance claim documentation.

Protocol Output

A third-party reviewable claim file including indexed photo sets and plane-by-plane measurements structured for independent verification.

Forensic Core Standards

How is "Functional Damage" defined under the Protocols?

Per Haag Engineering methodology, functional damage results in the diminishing of a material’s expected service life or water-shedding ability. The Inspector Roofing and Restoration Protocols™ focus on documenting fractures in the asphalt matrix and/or reinforcement mat when present and documentable.

What is the "Repairability Test" for brittle shingles?

We evaluate repairability per IRC R908. The Protocols assess whether a shingle can withstand the manipulation required for repair without creating granular fractures or thermal seal compromise. If repair attempts create secondary damage or compromise adjacent shingles, full replacement may be required to restore a code-compliant, weather-tight system—subject to policy terms and local AHJ requirements.

Storm Physics & Pattern Recognition

How is Wind Damage verified against IBC standards?

Verification is aligned with IBC Section 1507 and ASTM D7158. We document "compromised attachment points" where uplift forces have fractured thermal seals or caused nail pull-through. This evidence provides the technical basis for verifying functional loss of the roof's high-wind fastening system.

Damage Mechanics: Wind Damage Hub

Why is Collateral Indicator Mapping required for hail?

Hail evidence is strengthened through collateral impact mapping on "soft metals" (vents, flashing, valleys). This establishes the energy levels and directionality required for independent verification of storm consistency across the asphalt shingles.

Methodology: Mapping Protocol

Xactimate Scope Integrity

Do the Protocols follow Xactimate estimating guidance?

Yes. Our scopes are constructed based on Xactimate best-practice estimating conventions regarding line-item separation. We ensure system components mandated by IRC R905—such as drip edge and valley lining—are represented as distinct line items to ensure an accurate restoration budget structured for carrier review.

Audit: Audit My Scope

What is a Slope Map Index™ and why is it required for review?

The Slope Map Index™ is required for third-party reviewability. By assigning a unique ID to every roof plane, it provides critical location context for every photograph. This prevents data fragmentation and allows a carrier desk reviewer to independently verify damage frequency across the entire structure.

Data: Mapping Standards

The Building Code Rule

Are code upgrades required for system restoration?

Per IRC R905, a roof is typically restored to code-compliant status to meet permitting, warranty, and insurability expectations. The Inspector Roofing and Restoration Protocols™ document requirements for Drip Edge (R905.2.8.5) and Underlayment (R905.1.1) based on local AHJ and policy terms.

Library: IRC Requirements

How is Attic Ventilation (IRC R806) addressed?

The Protocols include a Net Free Venting Area (NFVA) calculation to ensure compliance with IRC R806.1. Correcting ventilation deficiencies during restoration is commonly required by manufacturer installation instructions to maintain warranty eligibility and prevent premature system failure.
