4.2 – Gables and copings – 1. General information 288 4.2. 1. General information The gables are the side closures of the roof, while the copings protect the head of the walls and the façade cladding from water. The edge areas are in fact particularly exposed to wind and rain: under the pressure of the wind, the water tends to rise along the façade; the roof and the overlap between the gable and the façade protect the connection area. The shape and type of closure of the edges determine the resistance to the action of the wind: the greater the height of the gable edge with respect to the ground level, the lower the extraction forces exerted on the roof cladding in the edge area. In the edge areas it is important to pay attention to the number and type of fixing clips. Swirling wind at the edge of the roof.
