There were four rainy roofs, but which most were only two or hut and that the wood structure was essentially made up of some masters, called bords connected together by currents and flat secondary beams.
Between the one and the other current then the smaller beams or ascelli on which the covered rested directly.
Cavalietti's roof was used more than anything else in the churches: however it was sometimes adopted even in the major classrooms of civil building.
The covered was of embryos, with the commissures protected by tegoli or rows of tiles arranged alternately with law and reverse.
The culminates of the roof were the culmination of the chimneys from which the water flowing down for the tiles or for the embryos (called for this also eaves), was gathered in the purchasing.
It seems that the roofs were also provided with downtations, called eyes from the oval shape of the openings...
... certainly one is that a dowel with oval window can be seen in the fresco of the Giottesca school representing the dream of the bishop Guido in the upper church of S. Francesco in Assisi.
Finally at the top, as a crowning, the fumaiuoli were, similar in the appearance of Torricelle, rarely quadrangular, more often round or polygonal, finished in the cone.
