A lighter, more cost-effective roofing system and method, which includes a rain diverting feature for directing rainwater and snowmelt away from an underlying sheet material and roof deck, is provided. The invention includes a sheet material having an upper surface and a lower surface. The upper surface includes one of a hook and loop fastener and the lower surface is configured to be attached to the roof deck. The present invention further includes a plurality of roofing tiles, each tile having hook and loop fasteners adhered to a back face which extend along the width of the tile at or near the uppermost and lowermost edges. Each rain diverting feature, which is a strip-like device with one surface made up of a plurality of hook portions and an opposing surface made up of a plurality of portions complementary to the hook portions, is positioned between and releasably attached to the hook and loop fasteners located on a side-edge portion of two adjacent tiles and the underlying sheet material, thereby releasably attaching the tiles to each other and to the upper surface of the underlying sheet material. The use of rain diverting devices to direct rainwater and snowmelt away from the underlying sheet material and roof deck allows for single lap tiling and thus less weight on the roof deck. It also allows for shorter tiles to be used, thus saving material cost.

A fastener plate for use in coupling an underlayment to a roof surface is disclosed. In use, the fastener plate is arranged and configured to enable subsequently applied liquid coatings to flow through a top surface of the fastener plate and into one or more cavities so that the liquid coating seals any openings created by introduction of the fastener. In one embodiment, the fastener plate may include a top surface, a bottom surface, a fastener opening for receiving a fastener, a plurality of openings formed in the top surface, and one or more cavities positioned between the top surface and the bottom surface, the one or more cavities being in fluid communication with the plurality of openings so that the liquid coating can flow through the plurality of openings formed in the top surface and into the one or more cavities to seal any voids created by the fastener.

An air and water barrier article comprised of multiple layers. The layers include a porous layer, a polymeric layer disposed on a front side of the porous layer, and a pressure sensitive adhesive disposed on a second side of the porous layer. In certain embodiments, a top polymeric layer having hydrophobic and UV resistant properties will be provided on a surface of the first polymeric layer opposite the adhesive layer. Each of the polymeric layers and the porous layer can be formed of a material(s) having a Tg between −40° C. and 20° C. The top layer, if present, can have a Tg between −5 and 30° C. The barrier article can provide nail seal ability and have a weight of less than 30 ounces per square yard.

A roof cover of a building under construction includes a heat shrinkable film stretched over the roof framing of said building under construction. The film brought into conformity with said roof framing through application of heat. The film may be formed by a number of adjoining sheets or strips of material.

The panel includes a water resistant barrier layer secured atop its outward facing surface. The water resistant barrier layer includes a skid resistant surface. The panels are made of lignocellulosic material. The water resistant and skid resistant surface may include indicia for aligning strips of tape or for aligning fasteners. A method for manufacturing the water resistant building panels is also disclosed and includes the steps of feeding paper onto a forming belt, depositing lignocellulosic material and the binding agent onto the forming belt so as to form a lignocellulosic mat, applying heat and pressure so as to impart the skid resistant surface on the paper, and cutting panels to predetermined sizes.

A multipart underlayment having a cap sheet and base sheet combined to form a pocket for securely holding building materials and environmentally-friendly manufacturing method for manufacturing the same.

A method of forming a sloped roof can comprise obtaining a base layer comprising at least one of a permeable mesh, woven fabric, non-woven fabric, plastic, foam material or combinations thereof; applying the base layer over a roofing substrate of the sloped roof; and applying a liquid roofing material to the base layer to form a liquid applied roof.

The pliable building membrane 1 is a non-flammable inorganic fabric 2 defining a first planar side 4 and a second opposite planar side 5. A halocarbon polymer in the form of a fluorocarbon polymer 3 is impregnated into the first planar side 4. The halocarbon polymer may be polytetrafluoroethylene (PTFE), fluorin plastic, ethylene tetrafluoroethylene and/or a tetrafluoroethylene perfluoro propylene co-polymer, for example. Various embodiments have differing ratios of halocarbon polymer to non-flammable fabric and this influences its vapour permeability. A suitable minimum target vapour permeability is approximately 0.15 μg/N.Math.s. An embodiment having a 1:1 ratio has a vapour permeability of approximately 1 μg/N.Math.s, which is well suited for use as a sarking-type material. The non-flammable fabric 2 may be a satin-weave fiberglass fabric or other non-flammable fabrics, such as basalt fibre fabric, or carbon fibre fabric, for example.

A synthetic nonwoven fabric having bonded fibers forming channels surrounding unbonded fibers forming raised slip resistant spots. The fabric is made by extruding hot polymer through a spinneret die onto a moving belt to form a sheet of random fibers, which sheet undergoes a calendering process between a pair of heated rollers, one of which rollers having a plurality of cavities defined in its surface. The resulting fabric can be laminated and otherwise combined with other layers as desired to provide an end product having good slip resistant properties.

A roofing underlayment capable of adhering to a roof deck comprising: (a) a roofing membrane having a first and a second major surface; and (b) a pressure-sensitive adhesive disposed on the first major surface of the roofing membrane and comprising: (i) at least one of butyl rubber or polyisobutylene; (ii) a first liquid plasticizer, preferably polybutene; and (iii) a tackifier, wherein the Tg of the adhesive is at most about 100 C. The adhesive provides high bond strength and excellent long-term heat aging, weathering resistance, as well as good low temperature properties while providing a moisture proof seam. A method for making the roofing underlayment includes applying the adhesive to the membrane then applying a release liner over the adhesive layer. A method for using the roofing underlayment comprises removing the release liner then adhering the underlayment to the roof deck by contacting the first to the roof deck.
