In the construction of a flat roof overhang, what is one component that must be identified?

In constructing a flat roof overhang, identifying a metal gravel stop is crucial because it serves a function that is vital for the longevity and performance of the roof system. The metal gravel stop acts as a barrier that prevents gravel from spilling over the edge of the roof, which can lead to water pooling and potential damage to the structure beneath. Its role is not only to manage the appearance of the roof edge but also to divert water flow and protect the underlying materials from water infiltration.

While components like tar paper, wood decking, and insulation board play important roles in flat roof construction, the metal gravel stop specifically addresses issues related to roof overhangs and edge details, making it essential for the integrity of the flat roof design. Properly installed, it assists in effective drainage, contributing to the overall durability and performance of the roofing system.
