Abstract:
A roofing underlayment with enhanced walkability and/or traction is provided. The roofing underlayment includes a base layer, a first coating layer adhered to a first surface of the base layer, and a melt-blown nonwoven layer adhered to the first coating layer. The melt-blown nonwoven layer enhances walkability by providing a rough surface on which roofing installers may walk.
