2.Product information

Underlayment is primarily used to separate the roof covering from the roof deck, shed water and provide secondary weather protection for the roof area of the building. 

Our roofing underlayment is a highly engineered, mechanically attached, coated woven synthetic roofing underlayment for sloped roofs under shingles, metal, tile or shakes. It’s comprised of PP spun bond nonwoven fabric and PP woven fabrics layers, which are made of 100% top virgin grade polypropylene, therefore totally unaffected by water, which means it is 100% inert to mold, lays flat. While non-woven fabrics are generally moisture permeable, woven scrim synthetic roof underlayment greatly enhances tear resistance and lay-ability. 

It comes in a 4’x250’ roll to reduced labor and waste. It can be used under any code-compliant mechanically attached roofing application. Our roofing underlayment are durable and strong, and easy to install, and has a walking surface to ensure safe working conditions.
