App Concept

VentCalc Pro

VentCalc Pro is a mobile app that lets contractors and builders model attic ventilation layouts, detect conflicts between soffit, edge, and ridge vents, and verify compliance with building codes. It replaces guesswork and manual inspection with 3D visualization and instant compliance checks.

Key Features

3D roof modeler to input vent types and locations
Automatic conflict detection between ventilation components
Code compliance checker based on roof area, slope, and vent types
Report generator for clients and inspectors

Target Users: Roofing contractors and residential builders in construction, especially those working on large developments with complex roof geometries.

Revenue Model: Freemium with $49/month pro tier for advanced modeling and reporting; $99 one-time per-project report fee.
