Most concrete and clay tiles are installed the same.

The statement is accurate because concrete and clay tiles share several similarities in their installation processes. Both types of tiles require a solid underlayment, typically one that can support the weight and shape of the tiles. The installation involves overlapping the tiles in a staggered pattern to ensure proper water drainage and to prevent leaks.

Additionally, the installation practices regarding fasteners, such as the need for adequate spacing and securing methods, are quite similar for both materials. Both types also require considerations for expansion and contraction due to temperature changes, which can affect how they are laid out and secured. Therefore, since the fundamental aspects of installation are alike for these roofing materials, it is true that most concrete and clay tiles are installed in a similar manner.
