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.

Abstract: A roof vent which may be mounted transversely across any roof ridge and or roof hip regardless of its contours or roof angles. A roof vent which may comprise of a combination pre-formed vent and shear resistant roof element, which may provide both ventilation from the interior of an attic space and provide a shear resistance value to the roof diaphragm. A roof vent element which may provide both attic ventilation and a shear value to the roof diaphragm. A roof vent element to provide openings to allow for the passage of air flow from the attic cavity to the outside atmosphere, a pre-formed one piece product made from a variety of metals and or plastics based upon installation requirements, said improved product made to be a strap which can be made to contour to either truss framing designs and or conventional roof framing designs.

Abstract: A reinforced roofing underlayment positioned between a roof support structure and an overlayment in order to provide a waterproof barrier for the roof structure. The roofing underlayment including an interwoven scrim comprising a mesh of interwoven strands of thermoplastic having a tensile strength sufficient to resist tearing when exposed to tensile loads from various directions. The interwoven scrim having a layer of waterproof material affixed to at least one side of the scrim in order to provide a weather-resistant barrier which prevents moisture and other external elements from passing through the roofing underlayment. The waterproof material is preferably a layer of thermoplastic film which is co-extruded over both sides of the scrim. The roofing underlayment may also include a slip-resistant outer surface in order prevent a person installing the roofing underlayment from slipping while walking on the roofing underlayment.
