A tile roof can last more than 100 years, especially when installed in the right climate. Clay and concrete tile roofs have been known to withstand hail, high winds, and even fire.2 Unlike wood, a tiled roof will never decay. Even though these roofs are very durable, they may require repairs or maintenance due to breakage from heavy impact. Once you install tile, you will never have to install another type of roofing again.1 Just in case, though, most manufacturers will offer a 50-year warranty.
Tile roofs are made from earth minerals, not synthetic materials, and they can be pulverized and recycled when they are removed.3 The heavy thermal mass of tiles helps regulate indoor temperatures.
A clay tile roof system is more expensive than an asphalt roofing system,2 but this is offset by the long life a tile roof will enjoy. Slate tiles are also costly.4 Concrete tile roofs are more economical. Installing tile roofing requires professional roofing contractors with extensive experience, which further adds to the cost. The tiles will need to be measured, laid in a specific pattern, and checked so that no moisture gets through. This is not a DIY project.
Your roof structure must be able to handle the weight of a tile roof, which may be as much as 2,000 pounds per square for a clay tile and 700 pounds per square for concrete tile. An asphalt roof, by comparison, weighs only around 275 to 425 pounds per square. If you’re replacing shingle roofing with tiles, you should consult an engineer to determine if structural reinforcement is necessary, which will add to the cost of the new roof.
While very durable, clay tiles, slate, and concrete tiles can be broken if they suffer a heavy impact, such as from falling tree branches, or even due to the pressure of walking on them.4 Repairs, when needed, can be expensive. Tile roofs are suitable only for roofs with relatively sharp slopes. They should not be used on roofs with pitches of less than 4:12.Clay and concrete tiles are available in many styles to match any aesthetic goal.
