What is a stone slab roof?

Slabs of stone cut into tiles were once a commonly used roofing material. While they're still used in some remote parts of the world, for the most part traditional stone slab roofs have long since been replaced by lighter, more easily manageable materials.

The weight of stone results in a heavy load on thewalls and foundations of a house, and impracticality of making tiles from stone means that with the exception of slate, the use of stone as a roofing material is rare these days, even in parts of the world where it's traditionally been a popular option.


Why install a stone slab roof?

Nowadays, a stone slab roof might be installed as part of the restoration of a heritage building, or as a decorative feature - although rarely as the main roof. Traditionally, stone slabs provided excellent insulation and unique looks. Stone slab roofs are also solid and virtually stormproof.


Where are stone slab roofs found?

Aside from small-scale hobby projects, stone slab roof are very rarely installed in most parts of the world. Because of its weight and the complexity involved with building a roof with stone, special permission and structural engineering would likely be required to use it in most circumstances these days.
