Vehicles, systems, and methods for inspecting and analyzing the condition of a remote location such as a roof are presented. A vehicle adapted for traversing an irregular terrain may be supported by wheels, or tracks, having partially collapsible treads to help the vehicle maintain a lower center of mass. The bottom surface of the chassis may have a higher ground clearance at an intermediate location, relative to the front and rear ends, to help the vehicle maintain a lower center of mass when crossing ridges such as roof peaks. A vehicle for roof inspections may include a shingle lifter. A system for collecting and storing inspection data may include an onboard imaging system with multiple cameras and a control system with a wireless router, together with a remote tablet computer having a wireless transceiver, a user interface, and a display. Vehicles and systems may gather and analyze data, and generate revenue by providing data, analysis, and reports for a fee to interested parties.
