Best Roof Protection: Concrete Roof Tiles

Concrete Roof Tiles Have Long Life Span

Concrete Roof tiles have had a long history of durability and beauty. The first cement-based tiles were made in 1884, at Kroher cement factory in Staudach, Bavaria by a mixture of cement, sand and water. In the early 1900s, coloring pigments were added to concrete roofing tiles in England, Holland, and other European countries, which enhanced the appearance of clay. Years later, concrete clay tiles where enhanced, by improving colourings, coatings, and surface textures. 

In the early production of concrete roof tiles, were handmade or by semi-automated machines. As innovation progressed, over the past century, manufacturing concrete roof tiles, become more economical than previous roofing products, including clay roof tiles, and lasted longer. In the early 1920s, machine known as the Ringsted, passed a line of cast-iron pallets or molds, under a hopper that poured a concrete mix into the molds. After World War Two, the popularity of concrete roof tiles started appearing in the southwestern United States, and currently are the fastest growing segment of the roofing materials manufacturing industry. In 1961, eighty-two percent of domestic roofs in Great Britain had concrete roof tiles. In the current production of concrete roof tiles, process an acrylic efflorescence preventive sealer that coats the surface of the tile after manufacturing. Manufactures of concrete roof tiles learned, that designing smaller tiles, held up longer and were tougher than the larger sheets.
