There are so many options for roofing materials, so it is imperative to do your research on the best alternative for your location, style, and budget. One of the most durable choices is ceramic roof tiles. However, there are negatives for installing clay roofing tiles too.

The Pros and Cons of Terracotta Roofing Tiles for Your Home | Home Owner Ideas
Terracotta clay roof tiles are attractive, impermeable and durable. Terracotta is a natural material, made from clay that is fired at a high temperature until it vitrifies or fuses. Vitrification creates a hard, waterproof surface that withstands rain, snow, cycles of freezing and thawing and wears well in coastal areas with salt air. They are fireproof, last up to 100 years or more and are almost maintenance-free. Because they are made from clay, terracotta tiles are easy to recycle and do not harm the environment.
Clay roof tiles are traditionally red, which is a moderately reflective color. Light-colored roofs, also called cool roofs, have higher reflectance and emissivity than dark-colored roofs. More than 90 percent of the roofs in the United States are of dark-colored materials which are low-reflectance and can reach temperatures of 150 to 190 degrees F. Cool roofs stay cooler, sometimes as much as 70 degrees cooler than a dark-colored roof, resulting in lower energy costs and more comfortable building interiors.
With the interest in saving energy and using more environmentally sustainable building techniques, manufacturers have developed fired clay tiles that achieve higher reflectivity and emissivity indices. These tiles, available in many colors including the traditional red-orange terracotta, achieve cool roof values. Several manufacturers produce clay tiles that meet Energy Star specifications.

Laying out a roof with clay or concrete tiles can be tricky. If you haven’t done roofing before, you have to think ahead or your roof will not look symmetrical. This video gives a very good step by step process:
You might wonder what the negative points to using these sturdy tiles would be. Even though there are many benefits of using ceramic roof tiles, there are some disadvantages as well. The cost is the paramount issue, but not just the price of the tiles. The need for reinforced roof trusses is also part of the expense.

Obviously, the biggest drawback is its initial installation cost. When compared to asphalt shingles or even basic metal roofing, tile roofs can cost several times as much to put up. They are, however, similar in price to slate roofing–the only other kind of material that can hold up as long or surpass the life expectancy of tile. Additionally, tile roofs (and slate roofs, as well) are not only heavy, but brittle. Not only might they require added structural reinforcement to install, but when a problem does occur, they can be difficult to work on since the individual tiles can break under the weight of a worker.
