ABOUT CONCRETE ROOF TILE

Concrete roof tiles were first developed by a German cement manufacturer in 1844. Concrete roof tiles are made of cement, sand, water, and pigments. This mix is extruded at high pressure and cured for several days (unlike clay tiles which are fired). Concrete roof tile come in 3 basic profiles: "S tile", "Double Roll", and "Flat". "S tile" attempts to look like barrel tile and are either high or low profile. "Double roll" can be best described as being "W shaped" or as having two small humps. "Flat tile" comes in a variety of finishes such as smooth, broom swept, slate like, wood grain, split shake, etc.

Concrete roof tile are given their color by having pigment added during the mixing (generally referred to as "color-thru" tile) OR by being slurry coated with a cementitious mixture after extrusion. Slurry coated tile are usually selected when a bright or high contrast blended color is desired. "Color-thru" tile provide a more subtle appearance and have less color variety options but are of higher quality and are much more colorfast than slurry coated tile.

Unlike petroleum based shingles, concrete tiles are NOT FLAMMABLE. Concrete roof tiles are also a "green product" due to their low embodied carbon and low embodied energy; and, are also a much better insulator than shingles (although clay is superior). Asphalt shingles are NOT GREEN as they are made from petroleum products, offer almost zero insulation, and need to be replaced every few years.

Concrete roof tile do require occasional maintenance to keep them free of mildew, algae, moss, and mold. Every few years (depending on roof location, pitch, orientation, etc) it will be necessary to lightly pressure wash the roof and then coat it with a clear acrylic sealer.
