Flow-Thru Gravel Stop (FTGS)
FTGS is our oldest solution for retaining ballast stone on a single ply roof while allowing water flow off. Manufactured from 0.040” aluminum and perforated on its face side with 3/16” holes @ ¼” staggered centers allows a 50% open face area without greatly affecting the strength. Joint treatment is a 4” factory notched lap joint which must be sealed as required with the primary roof membrane. FTGS can also be used with aggregate surfaced built-up roof systems for absolute positive drainage. Custom sizes are available.
Gravel Stops…Roof gravel stops are used at the roof termination on the perimeter of a structure for a variety of roof types such as EPDM Singly-Ply, Thermoplastic, Modified Bitumen and Built-Up roofing systems. These systems are designed to protect the structure from damage due to water penetration while offering superior wind uplift resistance.
Our gravel stops and fascia systems come in a variety of types, styles, profiles, materials, thicknesses and finishes. Each system is customizable to give a unique and professional finish to low sloped roof edges for commercial applications.
