The omission of edge covering on a concrete tile roof primarily exposes the edges of the tiles, leading to a lack of protection against corrosion. This is significant because concrete tiles, while durable, can still be subject to environmental factors like moisture and adverse weather conditions that may lead to deterioration over time. Without the edge covering, the raw edges are more susceptible to damage, which can eventually impact the structural integrity and lifespan of the tiles.

While it is true that this situation could contribute to other issues such as roof leaks or reduced wind resistance, the fundamental concern directly related to the omission of edge covering is that the edges are unprotected against corrosion. Protecting these edges helps maintain the overall performance and durability of the roofing system. It is critical in roofing design to ensure all components have the necessary protection to resist environmental impacts.
