What is the minimum number of fasteners required for clay perimeter roof tiles?

The minimum number of fasteners required for clay perimeter roof tiles is one per tile. This requirement is in place to ensure that the tiles are securely attached to the roof structure, providing sufficient resistance against wind uplift and other environmental factors. Using one fastener per tile allows for an efficient installation while still maintaining adequate stability.

Clay tiles are relatively heavy, and their interlocking design typically provides additional protection against movement. Therefore, the use of one fastener is often enough to keep them firmly in place, minimizing the risk of tile displacement. In various building codes and installation practices, the recommendation of one fastener per tile is common unless specific wind load requirements dictate otherwise.

While other options suggest more fasteners or none at all, these would not align with standard practices for ensuring the durability and safety of the roofing system using clay tiles.
