Sustainable Roofing, Across the Ages

The origin of clay roofing tile can be traced back in time independently to two separate parts of the globe. The first is China around 10,000 B.C. during the Neolithic Age, the second in the Middle East a short time after. The spread of clay roof tile spread from these regions into Asia and Europe and was later used by the likes of the Egyptians, Babylonians, Greeks, and Romans. Clay roof tile eventually reached America when European settlers established its use in many locales during the 17^th century.

One of the most important reasons for the rise of clay tile during America’s Colonial Period was a growing concern about fire. Devastating fires in London in 1666 and in Boston in 1679 prompted the establishment of building and fire codes in New York and Boston. Those codes, in turn, promoted the use of tile roofing. In later years, clay roofing tile experienced surges in use. For example, it rose in popularity during the mid-19^th century with the introduction of Italianate Villa architecture and again near the end of the 19^th century alongside the trend for Romantic Revival architecture.¹ If anything, its history and prevalent use across centuries, continents, people, and architecture demonstrate its effectiveness and curb appeal.

Clay tiles were molded by hand until approximately 1870 when they began to be manufactured using machine extrusion.² Among historic roofing materials, the tile has one of the longest life expectancies, when the roof is regularly maintained.³

• US Tile Clay Roofing works seamlessly with the Westlake Royal™ Cool Roof System. The thermal mass and built-in above sheathing ventilation of the system also enhance energy efficiency and long-term energy savings.
• Because the tile reduces the heating and cooling related energy demands of the home, the amount of greenhouse gases emitted by the home is also reduced.
• The sustainability of clay tile is demonstrated by its ENERGY STAR and Cool Roof ratings.
• Clay roofing tile is fully recyclable at the end of its long life on the roof. Clay tiles may be pulverized and reintroduced into a tile process. Removed tiles still in serviceable condition may be reused as roof tiles. Additionally, clay tile may be recycled for use in sporting fields (for example, baseball fields). These recycled uses reduce landfill waste.
