Roof edge FLOW-THRU

ATAS’ Flow-thru Gravel Stops and Drain Bars provide a method to terminate the roof, and allow water to flow over the edge, while retaining gravel or stone ballast on the roof. Most commonly used at a gutter or low roof transitions, Flow-thru Gravel Stop and Drain Bar is furnished in 12’-0” lengths of mill or pre-finished aluminum (other architectural metals available upon request) that is perforated or slotted for proper water flow and gravel or ballast retention.
