In this way, roof ventilation systems are designed for each roof area, but they also need to be designed according to conditions such as the type of roofing material and roof slope, and furthermore, they need to be provided according to the color tone of the steel plate. In order for this combination to occur, it is necessary to produce a wide variety of products, and it is also necessary to store these products in inventory. In addition, roof ventilation devices have problems in that they have poor stacking properties due to their product shape, which is wide and thick, resulting in high logistics costs.
The ventilation devices described in Patent Documents 1 to 3 are all placed near the top of a sloped roof surface, and are placed on the eaves side as ventilation devices with predetermined watertight performance and predetermined ventilation performance. A front opening is formed in the front part located on the roof top side, a rear opening is formed in the rear part located on the top side of the roof, and a wind and rain guiding plate is arranged at a predetermined distance from the front part and facing the front opening. It is something.
However, the ventilation devices described in Patent Documents 1 to 3 do not provide the watertight performance and ventilation performance required for ventilation devices by using a top cover (a ridge cover in Patent Document 1, a top plate in Patent Document 2), In Patent Document 3, a long member (elongated member) is designed as an essential member.
