Where is a scupper most likely to be located?

A scupper is an opening in a wall or parapet that allows water to drain off a flat roof. It is specifically designed to channel rainwater away from the roof and prevent pooling, which can lead to water damage and structural issues. The presence of scuppers is most common on parapet walls, where they serve to direct water away from the building and ensure effective drainage.

In this context, the placement of a scupper on a parapet wall is critical because it allows for easy and efficient management of water runoff. A well-placed scupper will help to guide water away from the roof, which minimizes the risk of leaks or overflow. Understanding the function and ideal location of a scupper is essential for effective roof design and maintenance.
