The Meridional gothic architecture (XIV-XVth) is characterized by flat roofing. The new imaging defined in the Council of Trento (1545-1563) imposed more importance to the Renaissance city, as a new symbolic reference in the urban space. In the case of the Gothic Cathedral of Tortosa, the new reference with inclined roofs and water filtration problems caused the modification of the original flat solution of the cover. The typological and physical assessment revealed the constructive layers overlapped in the roof. This case is an example of restoration where the starting gothic profile has been restituted. The paper exposes the theoretical framework of the heritage intervention criteria, as well as the constructive solution given for the new roof of the Cathedral of Tortosa.
