<p>Rooftop covering structure (1) for self-ventilated roofs (2) comprising at least one rectilinear section-bar (9) with a substantially inverted U- or Omega-shaped cross-section, which is suited to be positioned in the longitudinal groove (4) formed by the two slanted pitches (3) of the roof, astride the same slanted pitches (3), so as to surface externally from the longitudinal groove (4) between the impermeable. coverings (7) of the slanted pitches (3), and has the two major side edges (9a) substantially L folded so that each of said side edges can stably rest on the boarding (6) of a respective slanted pitch (3); the rectilinear section-bar (9) has, on at least one of its lateral sides (9b), a series of through-slots (11) and a series of projecting protective hoods (12), each of which protrudes from the outer surface of the section-bar lateral side (9b), immediately above the upper longitudinal edge of -a respective through-slot (11), and then lowers down to substantially the height of the lower longitudinal edge of the same through-slot (11), at a predetermined distance (d) from said lower longitudinal edge, so as to form a protective canopy (12) that covers the through-slot (11).</p> |
