An unmanned autonomous vehicle assessment and reporting system may conduct patch scan analyses of a roof. Damage points on the roof may be evaluated for severity and assigned a severity value. A remediation status may be objectively developed for one or more faces of the roof based on the number of damage points within a patch region of a defined size and the severity value of each of the damage points within the patch region. A visualization system may overlay markings, such as color-coded markings, to display a representation of a roof, patch regions, damage points, and/or severity values.
