In this case, the flow of rainwater on this type of construction is slower and the risk of infiltration is greater. Indeed, 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 water flow. In this case, rainwater may run off in the opposite direction to the slope and infiltrate between the tiles.
