Roof Inspection Standards: What HAAG Master Level Actually Requires

The baseline standard is the NACHI Standards of Practice, which most general home inspectors follow. It allows ground-level inspection of roof-covering, flashing, vents, gutters, and chimneys. A forensic-grade inspection goes further by adding HAAG Master Level on-roof walking, ASTM-aligned thermal imaging, and adjuster-compatible documentation.

HAAG Master Level is the highest tier of HAAG Certified Inspector credentialing. It requires a 3-day in-person intensive training, a comprehensive exam, and annual recertification. The credential covers weather characteristics, building codes, roof calculations, inspection safety, installation standards, weathering patterns, and damage assessment methodology. The credential is held by the majority of insurance adjuster field staff. JDH owner Jim Dodson holds HAAG cert #992109047 since 2021.

A NACHI home inspection covers the roof as one of many systems, typically with a 10-15 minute visual review from ground level or eaves. A HAAG forensic inspection is specifically for the roof and runs 60-90 minutes on-site, includes physical walk-the-roof access, applies forensic damage-assessment methodology to every finding, and produces adjuster-compatible documentation. See the full comparison in Forensic vs Standard Inspections.

A roof inspector alone doesn't require state licensing in most US states. But if the inspector is also performing or quoting any work, they must hold the relevant state contractor license (in Maryland, an MHIC license; in Virginia, a VA DPOR Class A, B, or C license based on contract value). JDH holds both (MHIC #137491, VA #2705192986). HAAG certification is voluntary credentialing that signals forensic competence beyond state licensure.

Several ASTM test methods are relevant to forensic roof investigations: ASTM E2128 (water leakage of building envelopes), ASTM E1105 (field water-penetration testing for walls/windows), ASTM D7281 (water-migration resistance through roof membranes), ASTM E907 (uplift resistance of adhered membrane systems), and ASTM C1153-10 (location of wet insulation in roofing systems using infrared imaging). JDH's FLIR thermal scanning aligns with C1153-10 methodology. ASTM International publishes the standards.

Yes. JDH is a member of the National Roofing Contractors Association (NRCA) and installations follow the NRCA Roofing Manual best practices. For inspection purposes, NRCA standards inform what a properly installed system should look like, which is how we assess whether existing installation defects are causing the failure we're observing. NRCA membership + Owens Corning Platinum + ProVia Platinum credentialing means manufacturer warranties stay valid on JDH-installed systems.

At minimum: a written report describing the condition of the roof, flashing, gutters, attic, and ventilation. A forensic-grade report adds: location-marked photos of every finding, narrated video walkthrough, FLIR thermal scans where applicable, PCC narration (Problem, Cause, Consequence) for each finding, and a remaining-service-life estimate. JDH delivers all of this before the inspector leaves the property. Sample report available on request.

Yes, when the inspection is performed to HAAG forensic standards. JDH reports are structured around the same cause-of-loss + pre-loss condition documentation that adjusters look for. The HAAG credential held by JDH (Jim Dodson, cert #992109047) is the same credentialing standard most adjuster field staff hold. For storm-related losses, we also meet your adjuster on the roof.
