This paper examines an eighteenth-century roof in Chinchero, Peru to show the critical role played by roofs in Andean communities across time. Roofs can reveal identity constructions, continuation of traditions, adaptations to new influences, and relationships to local environments and the sacred. We present a discussion of the importance of roofs in architectural history, the critical role played by roofs in Inca architecture, and a description of the colonial period roof in Chinchero, along with its facture, dates of construction, botanical identification, and the environmental zones from where these items could have been gathered.
