ABSTRACT:
A novel ridge ventilation apparatus for a roof provided with ridge tiles at a ridge, comprises at least one air duct provided above a rafter, and at least one ventilator provided in lieu of several ridge tiles and is shaped substantially identical to that of the ridge tiles, and ends of the top frame are fixed to ends of the ridge tiles. Since the appearance of the ridge ventilators are substantially the same as that of the roof ridge, no unusual impression is aroused as has been so for a conventional roof in which ventilators project above the roof ridges.
