Definitions for "Roof Drain"
The termination or fitting at the roof of an interior drain or leader, for draining rain water from nominally flat roofs.
The termination or fitting at the roof of an interior drainor leader for draining rainwater from nominally flat roofs. The fitting itself usually consists of a base with or without a sump, a clamp ring and gravel stop, and a basket strainer to prevent debris clogging the drain. The base is sometimes fastened to the leader with an expansion-sleeved fitting. Some roofers dispense with the specially engineered roof drains, and use instead a flanged copper pipe stripped into the roofing felts with the end projecting loosely inside the leader.
