App Concept

RoofGrip Inspector

A mobile app and sensor kit that allows roofers and inspectors to verify nailing quality during installation. The kit uses a magnetic stud finder array to detect nail penetration into rafters from above the roof, logging results per nail. It eliminates the need for attic inspection and provides a real-time report.

Key Features

Magnetic sensor array to detect nail depth and rafter connection
Real-time nailing verification with red/green indicator
GPS-tagged nailing map per roof area
Cloud report for homeowner and warranty documentation

Target Users: Roofing contractors, home inspectors, and homeowners needing quality assurance on roofing installations.

Revenue Model: $199 for sensor kit, plus $9.99/month app subscription for report generation and cloud storage.
