RoofCrack Scanner

Overview

RoofCrack Scanner is an enterprise-grade structural forensics and building envelope diagnostic platform on the Sensifai Marketplace. Combining high-resolution computer vision with multi-scale neural feature extraction, it transforms aerial drone footage and smartphone photos into millimeter-calibrated fracture diagnostics, moisture infiltration mapping, and contractor repair scopes in under 3.5 seconds.

The Problem

Concealed building envelope fractures and roof joint separations result in billions of dollars in structural degradation, rot, and ceiling collapses each year. Homebuyers lose an average of $15,000 on undetected roof defects, while certified on-site structural engineer callouts cost $300 to$500 per visit with 3 to 7 days scheduling delay. Routine maintenance checks are often neglected due to prohibitive inspection costs and manual tape measure inaccuracies.

The Solution

RoofCrack Scanner provides immediate, sub-millimeter computer vision pre-screening directly from high-resolution imagery. Within 3 seconds, the platform classifies defect types (thermal shrinkage, shear fractures, mechanical hail breaks, parapet expansion cold joints), computes crack gap breadth and length, calculates moisture seepage probabilities, and produces prioritized contractor repair work orders with projected material costs.

Key Capabilities

• Sub-Millimeter Caliper Measurement: Quantifies fissure gap width with 0.1mm calibrated precision, distinguishing cosmetic hairline checks from structural hazards.
• Multi-Substrate Coverage: Calibrated across asphalt composition shingles, interlocking terracotta tiles, reinforced concrete deck slabs, slate, and brick masonry parapet walls.
• Thermal & Moisture Seepage Profiling: Correlates surface discoloration with moisture ingress vectors to predict water infiltration into ceilings and decking.
• Automated Contractor Action Plan: Formulates 3 concrete remediation steps, recommended sealant chemistries, and projected repair budget ranges.
• Transparent Prepaid Metering: Seamless pay-as-you-go billing (€0.05 per inspection) directly integrated with Sensifai Gatekeeper and instant Logto OIDC authentication.

How It Works

1. Upload a high-resolution smartphone photo or aerial drone survey image of the target roof surface or wall foundation.
2. Sensifai Vision Core analyzes the defect contours, computes displacement dimensions, and calculates moisture infiltration risks.
3. Review the interactive forensic canvas with toggleable caliper grid overlays and thermal moisture heatmaps, or download the full structured engineering JSON report.
