Definition
Roof tiles are typically made of terracotta or concrete, and form a regular pattern of ridges on a roof.  Roof tiles are defined by their structure and thickness: clearly laid out lines with shadows on each row, and ridge caps. As such, this includes any tile materials (primarily terracotta or concrete), regardless of colour.
