Atlas Roofing has introduced WeatherMaster® PolySeal™ SE — a durable, self-adhering modified composite roof underlayment that has a selvaged edge and is crafted to withstand the rigors of metal roofing applications. This is a tough, non-scratch 50 mil roof underlayment designed to provide metal roofs a resilient barrier to storm damage, UV degradation and moisture issues. It has a soft-surfaced polyester face that allows for direct-to-deck application. It also offers the application benefit of cold-temperature adhesion, yet retains exceptional thermal stability under intense heat. The underlayment prevents unwanted moisture entry because it seals uniformly to the substrate and even around nail penetrations.Because Atlas WeatherMaster PolySeal SE is self-adhering, no special bonding agent, heat treatment or other equipment is needed for a proper metal roof installation.
