When installing roof tiles, what is a critical consideration for structural integrity?

When installing roof tiles, a critical consideration for structural integrity is tile weight. The weight of the tiles directly impacts the load that the underlying structure must support. Roof structures, including rafters and trusses, are designed to handle specific weight loads, including the weight of the roofing materials.

If tiles are too heavy for the structure to support, this could lead to structural failure or sagging over time. Proper assessment of the roof's load-bearing capacity is essential when selecting tiles, ensuring that they conform to local building codes and standards. While tile exposure and design are important for aesthetic and functional reasons, such as weather resistance and water drainage, they do not directly influence the structural integrity of the roof in the same way that the weight of the tiles does.
