Various Stone Options For Tile Roofing

In the last couple of decades or so, a new trend has begun to appear in how people cover their buildings; namely tile roofing. It's still the case that most homes use older types of coverings, such as asphalt shingles to protect their roofs from the elements. But tiles have historically been very durable and they are becoming increasingly available, as many home builders now carrying slate roofing tiles. Other types of stone can be used for this purpose as well. From vanity tops to kitchen countertops to tiles on the roof, granite, too, has become more widespread as a tiling material.

Many people immediately think of the rounded, terracotta tiles from warmer climates, as soon as someone mentions tile roofing. And it's true that if roof coverings aren't made of the more typical asphalt, they will usually be derived from clay, or perhaps even concrete. But the choices are increasing now. Roofing slate tiles are fairly easy to manufacture, since they are made from metamorphic rock that was created under pressure, resulting in the minerals forming into parallel lines. All that's needed, really, is to split the stone either into flat slate tile flooring or roofing tiles.

But as well as the roofing slate tile option, you will also find that granite particles are formed into roofing tiles. Many of these materials, when cut and shipped as actual cut tiles seem to come primarily from India and to a lesser extent from China, in mainly grey or blue granite colors. But this stone is used in other ways as well, cut into chips that are set between two layers of roofing felt. So while granite is increasingly being used, it doesn't yet appear to be as plentiful as slate in actual roofing tiles.

Using slate tiles on the roof means a more durable, long-lasting covering, yet a builder or homeowner can't ignore a few potential drawbacks to the material. For one thing, slate is more brittle than other materials, so slate roofs might need more repair if installed in a region that gets a lot of hail. Slate is also heavier than other materials, so the roof might need fortification to support the extra weight. Yet slate tile roofing is attractive because of its uniform color, smoothness and shape. One shouldn't ignore the possible problems, but if such things aren't a major obstacle, then slate tile is definitely an option for a roof covering that will last.
