To provide a roof ventilation structure capable of securing ventilation performance during snowfall.SOLUTION: A roof RF is a flat roof in which an outer periphery of a roof body 20 is surrounded by an eaves part 30, and a plate-shaped throating member 80 is provided along an upper part of a space for ventilation provided along a gap between an outer wall 10 and the eaves part 30. Further, the throating member 80 is provided with an upper wall part 81 arranged with a first ventilation interval Lb in the vertical direction with respect to the outer wall 10, and a vertical wall part 82 arranged with a second ventilation interval Lc in the horizontal direction with respect to the outer wall 10 and forming an opening for ventilation facing downward between the vertical wall part and the outer wall 10. Then, a ventilation path shown by an arrow Vp of a two-dot chain line is formed from the opening for ventilation to an attic space of the roof RF through a portion between the throating member 80 and the outer wall 10 with the first and second ventilation intervals and also via the eaves part 30.SELECTED DRAWING: Figure 2
【課題】降雪時の換気性能を確保可能な屋根の換気構造を提供する。【解決手段】屋根ＲＦは、屋根本体２０の外周が庇部３０に囲まれた陸屋根であり、外壁１０と庇部３０との間に沿って設けられた換気用の隙間の上部に沿って板状の水切部材８０が設けられている。さらに、水切部材８０は、外壁１０に対して上下方向に第１の換気用の間隔Ｌｂを空けて配置された上壁部８１と、外壁１０に対して水平方向に第２の換気用の間隔Ｌｃを空けて配置されて、外壁１０との間に下方を向いた換気用の開口を形成した縦壁部８２とを備える。そして、換気用の開口から、水切部材８０と外壁１０との間の第１、第２の換気用の間隔を空けた部分を通り、さらに、庇部３０を介して屋根ＲＦの小屋裏に至る二点鎖線の矢印Ｖｐにより示す換気路が形成されている。【選択図】図２
