Forensic EngineeringFor Property Claims

Independent, defensible engineering determinations for the insurance restoration industry. Every inspection is performed by a licensed professional engineer and peer reviewed before we send you the inspection report. Our reports are built on evidence-based findings and transparent methodology. We deliver the highest level of quality and professionalism combined with the fastest turnaround in the industry.

Steep And High Experts

We access every roof we are assigned to inspect, no exceptions. Safety is our top priority, so our team is expertly trained in accessing steep and high roofs with no compromise in quality or safety. In the rare event that any portion of a roof is truly inaccessible, we utilize drone technology to fill the hands-on documentation gaps.

Roof access on every job

Steep and High Roofs accessed directly

Many industry professionals have gone the way of substituting a hands-on inspection with a drone flyover. We are committed to leveraging technology as a supplement to direct inspection — never a replacement for it. Repairability, fastener condition, test-square sampling, and many other aspects of a proper inspection simply cannot be evaluated from the air, so our team physically accesses the roof on every assignment. The findings in your report come from direct, hands-on observation — not from interpreting a photo.

Drones for hard-to-reach places

Inaccessible roof facets documented thoroughly

Our certified FAA Part 107 unmanned aircraft pilots thoroughly document any portion of a roof that genuinely cannot be reached by hand. High-resolution aerial imagery closes the documentation gap rather than leaving it to assumption, so every facet of the roof is accounted for and nothing goes unexamined.

The gold standard in forensic evidence: on-site, PE-verified empirical data collected across thousands of inspections by Trinity's qualified forensic engineers. Hail dents and spatter, collateral wind and hail damage, and impact damage to roofing materials — all documented in person, at the property. Radar can be inconsistent, and some counties have coverage gaps where no trained spotters are nearby; ground-truth field data fills those gaps. This proprietary layer is the defensibility core of Severe Weather Intelligence™.

A 10-year NEXRAD Level-3 Hail Detection Algorithm dataset — over 7.2 million radar-derived hail detections across the contiguous U.S. — pulled directly from NOAA's Severe Weather Data Inventory. When a storm event is recorded on the ground, we cross-reference it against what 159 WSR-88D radar sites actually detected in the same grid cell at the same time.

Wind speed, temperature, and atmospheric conditions at the property are estimated using Inverse Distance Weighting interpolation across nearby Automated Surface Observing System stations — real physical instruments, not modeled data. IDW assigns weighted influence to each surrounding station based on distance, producing a defensible site-specific estimate with a documented confidence metric.

20+K Inspection experience on every single job

Once each report is written, it is subjected to peer review - our expert team collaborates on every job

SPC Mesoscale Discussions are issued by NOAA's Storm Prediction Center when atmospheric conditions are evolving toward organized severe weather. Each SWI report retrieves and links any MCDs active on the date of loss — providing a fifth, independent government-issued confirmation that severe weather conditions were present at the regional scale.
