In steep-slope roof fluid mechanics, the apex—the horizontal ridge line and converging hip intersections—operates as the highest stress concentration point on the entire building envelope. When high-velocity storm fronts advance across coastal or highland terrain, the wind stream cannot pass through the windward roof plane. As air compresses against the incline, it accelerates rapidly toward …
