Liquid Roofing MasticGarland recently introduced a new single-component liquid-applied mastic that is durable and easy to apply. The Tuff-Flash™ liquid flashing system provides water protection and weathering capabilities. It is an asphalt polyurethane that adheres to asphaltic membranes as well as a variety of metal surfaces. This includes SBS, APP, and smooth or mineral surfaced asphalt roofs. The liquid flashing system capitalizes on the benefits of both asphalt and urethane chemistries, and actually builds strength over time as it cures. For more information, visit
