WeatherMaster PolySeal SE

April 29, 2015

WeatherMaster PolySeal SE is a self-adhering modified composite roof underlayment that provides a resilient barrier against storm damage, UV degradation, and moisture issues on metal roofs.

The non-scratch 50-mil underlayment offers the application benefit of cold temperature adhesion yet retains exceptional thermal stability under intense heat. It prevents unwanted moisture entry because it seals uniformly to the substrate and around nail penetrations.
