The anatomy of a residential roof is complex. The understanding of rooftop geometry and structure has important real world applications including:

● Roof Damage Inspection & Detection

● Residential Solar Rooftop Potential

● 3D Modeling and Digital Twins Cities

Dataset Acquisition:

[Figure]

● Data acquired from over 20k residential roof inspections from across the United States using DJI drones

● Diverse: includes single and multi family homes (e.g. apartment complexes) from rural and urban locations

● Overhead and oblique imagery acquired for analyzing inspecting rooftops as well as performing multiview reconstruction to estimate rooftop structure and height
