Final answer:
Omitting the edge covering on a concrete tile roof will likely lead to water infiltration, potentially causing damage to the building structure and reducing the roof's overall durability.
Step-by-step explanation:
If you omit the edge covering for a concrete tile roof, the result will likely be water infiltration. The edge covering, typically called flashing, is designed to ensure water does not enter the building around the edges of the roof tiles. Without this protective barrier, water can seep through the gaps between the tiles and the roof structure, causing potential damage to the underlying roofing materials, the interior of the building, and possibly leading to the growth of mold or mildew.
Omitting the edge covering will not improve insulation, aesthetics, or durability. In fact, ignoring this crucial part of a roofing system would diminish the roof's effectiveness and could lead to costly repairs over time as water damage takes its toll.
