Metal roofing will give you that smooth designer look. Metal sheeting is a shiny metal sheet which is shaped to the suitable profile you are asking for. Styles we install and supply are corrugated, trimdek, klip lok and spandek. There are a lot more profile and styles, though the ones mentioned are most commonly used. Klip lok is a profile that has a bracket fixed to the batten and the klip lok sheet is placed on top of klips and then locked into clips, giving you that screwless smooth look. Other profiles are fixed through ribs or pans to fix sheeting to batten.
