Tile Roofing Systems have been part of roofing construction from as early as the 3rd millennium BC. The spread of the roof tile technique was in direct correlation with the rise of monumental architecture in ancient Greece, where only the newly appearing stone wall (which were replacing the earlier mudbrick and wood walls) were strong enough to support the weight of a tiled roof. The production of Dutch roof tiles started in the 14th century when city rulers required the use of fireproof materials. At that time houses were made of wood and straw roofing, putting whole cities at risk of destruction by fire.
Tile Roofing Systems are designed mainly to keep out rain, and are traditionally made from locally available materials such as terracotta or slate. In South Florida concrete and clay roofing tiles are among the most popular choice, for both their architectural appeal as well as their longevity. Modern materials such as plastic are also being utilized. Roof tiles are 'hung' from the framework of a roof by mechanically attaching them either with screws or a foam adhesive. The tiles are usually hung in parallel rows, with each row overlapping the row below it to exclude rainwater. There are also roof tiles for special positions, particularly where the planes of the several pitches meet. They include ridge, hip and valley tiles.
A modern technology that has been adapted to the tile roofing system are solar roof tiles. Dow Chemical Company began producing solar roof tiles in 2005, and several other manufacturers followed suit. They are similar in design to conventional roof tiles but with a photovoltaic cell within in order to generate renewable electricity. A collaboration between the companies SolarCity and Tesla produced a hydrographically printed tile which appears to be a regular tile from street level but is transparent to sunlight when viewed straight on.
