Which type of tile typically has a rise of less than 1/2-inch?

Flat profile tiles are characterized by their low-rise and smooth, flat surface, which typically measures less than 1/2-inch in height. This design helps to provide a sleeker appearance and is often suitable for applications where a low profile is desired, such as on roofs that need to minimize wind resistance or for aesthetic reasons.

In contrast, high-profile tiles are designed to have a more pronounced rise, which contributes to better water drainage and can give a more textured appearance to roofing. Standard clay tiles have varied profiles but are generally thicker than flat tiles, while slate tiles can also come with a more dramatic rise, depending on their style and installation preferences. Thus, flat profile tiles are specifically known for their minimal rise, making them the right answer in this context.
