Waterproofing Systems (Roofs): Liquid Membrane Flashing Systems

Note to Reader

Liquid membrane flashing systems are manufactured from various bituminous and non-bituminous materials. These manufactured proprietary flashing systems are specifically designed for use to flash unusual roof penetration shapes or roof details that are difficult to flash with traditional membranes.

Liquid membrane flashings are available as one or two part component systems that require reinforcement scrims for strength. To ensure quality installation, manufacturers’ proprietary application instructions must be strictly followed.

2-Part Component Systems

For use with fabric reinforcement only (refer to product Technical Data Sheet for proprietary reinforcement materials). These systems may be used on or within 200 mm (8") of the water plane.

Single-component Systems

(NOTE: these flashing systems have limited application within the RoofStar Guarantee Program, and may be used on upstand angles, support junctions and joints that are typically more than 200 mm (8") above water plane. These materials may also be used as a coating on galvanized flashings and other strip-in flashings requiring a coating (see RoofStar Guarantee Standards for SBS-modified Bitumen Roof Assemblies, 12.4 Strip-in Flashings)
