Abstract
A protective barrier laminate underlayment used to cover the surface of a structure, such as a house, just beneath the outermost, weather bearing layer. The underlayment has an adhesive layer on its lower side for securing the underlayment to the roof and a pattern of adhesive areas on its upper side for allowing a construction worker to walk on the underlayment without slipping. The upper adhesive layer also prevents tools and other objects such as stacks of shingles from sliding off of the roof during construction.
