1. A computer-implemented method for generating a roof estimate report, the method comprising: displaying a first and a second aerial image of a building having a roof, each of the aerial images providing a different view of the roof of the building; receiving an indication of a feature of the building shown in the first aerial image; modifying a three-dimensional model of the roof based on the received indication of the feature of the building; and displaying a projection of the feature from the modified three-dimensional model onto the first and second aerial images as a line drawing of the feature, each overlaid on corresponding locations of the feature on the first and second aerial images.
