Definitions
- the invention relates to the field of construction.
- the invention relates more particularly to the field of roofing elements, such as tiles, for producing roofing surfaces.
- Tiles are used in constructions for covering surfaces such as roofs.
- the tiles are arranged on the surface to be covered so as to have an inclination with respect to a horizontal plane to guarantee protection against rainwater while allowing rainwater to flow.
- the surface to be covered may have extreme inclinations. Indeed, on certain surfaces, the covering is operated by tiles arranged with a low slope inclination. In this case, the flow of rainwater on this type of construction is slower and the risk of infiltration is greater. In fact, in this type of construction, the wind has a greater impact on the water flowing over the tiles and can thus influence the direction of the water flowing. In this case, rainwater can be caused to run off against the slope and seep between the tiles.
- the tiles of the prior art comprise, on their outer surface commonly called the upper surface, an upper interlocking portion designed to be overlapped by an adjacent tile in the longitudinal direction corresponding to the line of greatest slope of the roof.
