Metal roofs can be safer and more secure when protected by an Atlas Roofing underlayment produced for those specific applications. WeatherMaster® PolySeal™ SE  a durable, self-adhering modified composite roof underlayment, 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 that provides 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. WeatherMaster^® PolySeal^™ SE is a unique underlayment that offers the application benefit of cold temperature adhesion, and yet retains exceptional thermal stability under intense heat. In fact, it has a 260°F melting point. It 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. It has a maximum exposure rating of 45 days and can also be used as flashing tape to provide a secondary water barrier.
Before the metal roof surface is installed, WeatherMaster^® PolySeal^™ SE can be applied to the dry roof deck surface during fair, dry weather in temperatures above 45°F. (In temperatures below 45°F, deck surfaces will need to be primed prior to application.)
As an added benefit, Atlas offers homeowners increased coverage of its Premium Protection Period on any Atlas Signature Select^™ Roofing System. WeatherMaster^® PolySeal^™ SE qualifies for this when purchased in combination with other qualifying Atlas products.
