The Dual-Layer difference for roofing
Layer 1 — Physical Inspection
Your RHI certified inspector physically examines every accessible roofing component using professional equipment including thermal imaging camera and moisture detection.
Layer 2 — AI Analysis
Every photo and thermal frame from the roofing inspection is analyzed by AI for patterns that the human eye can miss. Findings are cross-referenced and verified before appearing in your report.
