The roof system of a house can be roughly divided into two systems:sloping roof and flat roof.
The history of sloping roof systems can be traced back to ancient times.From the beginning of China's recorded history until the end of the Qing Dynasty,almost all buildings were built with sloping roofs.The same is true for foreign countries,but they are more distinctive and diverse,such as various pointed roofs,spherical roofs,etc.The flat roof system actually evolved from ancient castle structures and has been widely adopted in many high-rise buildings with the development of modern concrete components.Most sloping roofs use roof tiles.
As one of the oldest building materials,tiles have been widely used for thousands of years.Tile is the most important roofing material,which not only provides shelter from wind and rain and indoor lighting,but also has important decorative effects.With the continuous emergence of modern new materials,other functions of tiles are also constantly emerging.
There are many types of roof tiles,and the main classification method is based on their raw materials,including clay tiles,colored concrete tiles,asbestos water mixed wave tiles,fiberglass magnesium wave tiles,fiberglass reinforced cement(GRC)wave tiles,glass tiles,colored polyvinyl chloride tiles,fiberglass reinforced polyester lighting products,polycarbonate lighting products,colored aluminum alloy pressed products,colored coated steel pressed products,color steel asphalt felt tiles,steel insulation sandwich panels,glazed tiles,etc.Among them,clay tiles,colored concrete tiles,glass tiles,fiberglass magnesia tiles,fiberglass reinforced cement tiles,and oil felt tiles are mainly used for sloping roofs in civil buildings.Polycarbonate lighting products,colored aluminum alloy pressed products,colored coated steel pressed products,steel insulation sandwich panels,etc.are mostly used in industrial buildings.Asbestos water mixed tiles,steel wire mesh cement tiles,etc.are mostly used for simple or temporary buildings.Glazed tiles are mainly used for roofs or wall tiles in garden architecture and antique buildings.
