Scuppers
Scupper drains are used to provide an outlet through parapet walls or gravel stops on flat and built-up roofs to allow drainage of excess water. They can be used in conjunction with gutters and downspouts to divert the flow to the desired location, a particular concern with flat roofs.
Arapahoe Roofing and Sheet Metal installs scupper drains either with the outlet pipe passing through the parapet wall or with the outlet pipe passing through the roof deck, depending on the type of roof architecture.
