Devices, systems, and methods for inspecting and objectively analyzing the condition of a roof are presented. A vehicle adapted for traversing and inspecting an irregular terrain includes a chassis having a bottom surface that defines a higher ground clearance at an intermediate location, thereby keeping the center of mass low when crossing roof peaks. In another embodiment, the drive tracks include a partially collapsible treads made of resilient foam. A system for inspecting a roof includes a lift system and a remote computer for analyzing data. Vehicles and systems may gather and analyze data, and generate revenue by providing data, analysis, and reports for a fee to interested parties.
