Abstract: Pedestaled roof underlayment systems and methods are disclosed herein. A pedestaled roof underlayment system comprises a pedestaled sheet including a plurality of regularly spaced pedestals on one side and a generally flat surface on the other side. The system includes a multi-layer roofing underlayment including a slip resistant top layer, a UV protection layer and a strength layer. A reflective barrier layer may be included with the multi-layer roofing underlayment. The pedestaled sheet may be conical and/or tapered, and may have a top shape and cross section that may be circular, triangular, hexagonal and square.

Abstract: A roofing underlayment having a slip-resistant surface includes a woven polypropylene scrim laminated to a top layer made from a non-woven spun-bond polypropylene fabric. During lamination, the scrim is bonded to the top layer by a polypropylene coating that impregnates the scrim, thereby forming a structural bottom layer comprising the polypropylene-impregnated scrim. The non-woven fibers of the top layer provide a micro-textured, slip-resistant surface. A second polypropylene coating may be applied to the bottom surface of the bottom structural layer. An adhesive layer may optionally be applied either to the bottom surface of the bottom structural layer, or, if used, to the bottom surface of the second polypropylene coating.
