| An opening in the side of a wall or sheet metal edge detail which allows water to drain from the roof surface. Overflow scuppers are used as a secondary drainage method in case of interior drain blockage. Spillout scuppers allow water to run directly over the edge of a building onto another roof level or the ground. A downspout scupper (sometimes referred to as a collector or conductor head) channels water into a downspout which carries rain water to the ground or to a lower roof level. |
