What type of roof covering includes slate and clay?

Steep slope roofing encompasses various roofing materials designed for roofs that have a significant incline. Slate and clay tiles, which are traditional roofing materials, are commonly used in this type of roofing because they are excellent at shedding water, making them ideal for sloped surfaces. The steep pitch of the roof allows gravity to facilitate effective drainage, which is crucial for preventing water accumulation and potential damage.

In contrast, low slope roofing, flat roof systems, and green roofs either don't employ these materials or are suited for different design and functional requirements in roofing applications. Low slope roofing tends to use materials that perform well in minor slope situations, while flat roof systems often utilize waterproof membranes. Green roofs involve vegetation and require specific structural considerations that don't align with the use of slate or clay. Thus, the association of slate and clay with steep slope roofing highlights their ability to withstand weather elements while providing a durable and aesthetically appealing finish on inclined surfaces.
