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.

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.

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.

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.

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.

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.

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.

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.
