Clay & Concrete in Los Angeles

Clay tiles are produced by baking molded clay. The density of the clay is determined by the length of time and temperature at which it is heated. Colors of clay tiles range from shades of white, yellow, orange and brown.

The most commonly used clay color is the Terra-Cotta. Another alternative to these natural earth tones is to add enamels to the tile and make any color of roof tiles. This process is called “ceramic” and consists of spraying enamel over the tile before baking it.

High temperatures of the kiln permanently bond this color to the clay tile so it will not peel or fade. As a result there are a wide variety of tile profiles, styles, finishes and colors available. Because clay tiles are made from a natural earth derived material, they are environmentally friendly and easily recycled.

Clay tiles are resistant to strong winds and cannot be destroyed in a fire. Because of the way they are shaped, clay tiles protect the underlayment of your roof, while also creating an air pocket thereby helping to insulate and isolate any unwanted heat or cold from being transferred to your home’s attic space.

Clay tile is produced by baking molded clay into tile. Installation methods depend on the nature of the tile being installed; that is, whether it is two piece, one piece, interlocking or flat. Example of a clay tile roof. Concrete tiles are made of portland cement, sand and water in varying proportions.

Concrete tiles are made of mixture of sand, cement and water, which are molded under heat and high pressure. The exposed surface of a tile may be finished with a paint like material. Concrete tiles have additional water locks, or interlocking ribs on the edges that prevent water infiltration. Concrete tiles come in three main appearances:

1. Flat profile – no curves.
2. Low Profile – small curves and has a rise to width ratio equal to 1:5 or less.
3. High Profile: large curves and has a rise to width ratio greater than 1:5.

Concrete tiles can simulate the appearance of traditional clay tiles, wood shake, slate and stone. Like clay, concrete tile surfaces can be textured or smooth, and tile edges can be ragged or uniform. They are resistant to hail, wind, and fire, making them a very safe roofing material when properly installed.
