Roof tile

A concrete or other roofing tile is provided which simulates wood shake roofing, and which may be used in either a direct deck or batten configuration. The simulated wood shake configuration includes an angled cut portion by means of a butt treatment, and also includes the use of an elongate medial slot which has a rectangular configuration.

Roof tile design and construction

Compositions useful for making lightweight roof tiles. The compositions comprise in percent by weight: between about 2.0 to 4.1 latex (solids basis), between about 20.0 to 28.0 cement, between about 28.0 to 55.0 lightweight aggregate, between about 9.0 to 15.0 water, between about 5.0 to 35.0 standard weight aggregate such as sand, between about 0.0 to 8.0 filler such as limestone, and between 0.0 to 1.5 accelerating additive such as calcium chloride. Methods for making the compositions e.g. into lightweight roof tiles, are also disclosed.
