Abstract
Roofs with one or more slopes, represent an important part of a construction, having a double role: a role of resistance together with the entire constructive system and a protective role both for the other components of the constructive system and for the optimal unfolding of the various functions. The durability and the fulfillment of the mechanical requirements depend equally on the material used, design quality and execution quality. Industrialized roof structures can be a solution, under the current conditions, to meet these requirements. This article compares the traditional roof structures and the industrialized one.
