Clay perimeter roof tiles require minimum fasteners per tile?

Clay perimeter roof tiles require minimum fasteners per tile?

• A. Zero
• B. One
• C. Two
• D. Three

Answer: (B)

The key idea is securing tiles against wind uplift, especially at the roof edge. Perimeter clay tiles are exposed to wind and may shift if not fastened, so a minimal level of fastener security is required to keep each edge tile in place. Using at least one fastener per perimeter tile provides enough restraint to prevent movement and maintain the roof’s integrity under typical wind loads, while still allowing the weight and interlocking design of the tiles to contribute to overall stability. Zero fasteners would permit movement and potential leaks, and using more than one fastener per tile is usually reserved for higher wind zones or specific manufacturer recommendations—not the standard minimum. In many installations, one fastener per perimeter tile meets the common minimum requirement unless a local code or the tile manufacturer specifies otherwise.
