What is the appropriate slope of a roof for installing clay cladding?

The appropriate slope for installing clay cladding is typically a ratio of 1:2, which corresponds to a 50% slope. This slope is ideal because it allows for effective water drainage and minimizes the risk of water accumulation on the roof, which can lead to potential leakage and damage over time. A steeper pitch, such as the 1:2, ensures that rainwater runs off more efficiently, thereby protecting the integrity of both the clay tiles and the underlying structure.

Clay tiles require a sufficient slope to prevent retention of water, as they are naturally porous. If the slope were less steep, as in the other options, it would increase the risk of water pooling and could compromise the roof's performance. Thus, the selected slope of 1:2 is essential for achieving proper drainage and ensuring the longevity of the roofing system.
