For over two millennia, historic roof structures – of many different types and still in use today – have been protecting historic buildings against bad weather. Built in a great variety of shapes, historic roof structures have a significant heritage value and are now treated with more and more interest. Interventions necessary in order to meet the excellence requirements for historic roof structures exploitation demand a complex theoretical and practical knowledge, since the manner in which the mechanical work is carried out is one of the main fields that need to be mastered. The paper presents a synthesis related to the mechanics of historic roof structures, divided into frames having a Romanesque, Gothic, Baroque and Eclectic character, also focusing on the evaluation of their heritage value.
