A hail resistant roofing system and method includes a roofing substrate such as a shingle or tile or membrane having an array of exposed upwardly projecting features. The features may rise to sharp points and may have side surfaces that are angled relative to the plane of the roofing substrate. The features are spaced and arranged so that a large hail stone capable of damaging the roofing substrate will always impact one or more of the exposed features. This can break up the hail stone into smaller benign pieces or can redirect the energy and direction of the hail stone so that the impact is absorbed without damage to the roofing substrate.

A drainage component having a continuous, extruded mat having an upper face and a lower face. The mat includes a plurality of patterned three-dimensional structures, each structure spaced from all adjacent structures, and the plurality of patterned three-dimensional structures are provided in a plurality of linear rows or columns in a first direction.

This invention is a hip and ridge liner for a roof on a building. It is a waterproof and weather proof barrier that is installed on top of a hip line or a ridge line on a roof. Hip and ridge shingles are then installed on top of the hip and ridge liner. Embodiments of this invention include a plurality of external tabs which function to securely retain the hip and ridge shingles and keep them in place for many years. Other embodiments of this invention include a plurality of internal tabs which function to securely retain the hip and ridge shingles and keep them in place for many years. Other embodiments of this invention include a plurality of shingle retaining clips which function to securely retain the hip and ridge shingles and keep them in place for many years.

Some embodiments of the present disclosure relate to a roofing system. In some embodiments, the roofing system includes a first roofing material, wherein the first roofing material comprises a top surface and a bottom surface. In some embodiments, the top surface of the first roofing material comprises a nail zone with a plurality of fines. In some embodiments, the roofing system includes a second roofing material, wherein the second roofing material comprises a top surface and a bottom surface. In some embodiments, the bottom surface of the second roofing material comprises a plurality of fines. In some embodiments, the roofing system comprises and a patterned adhesive, which directly contacts at least a portion of the plurality of fines in the nail zone and at least a portion of the plurality of fines on the bottom surface of the second roofing material.

In at least one embodiment, a microporous membrane having a moderate to high water vapor permeability and high liquid water penetration resistance is disclosed. The microporous membrane may be used in building applications, including as or as part of a building wrap, a rain screen, a roofing underlayment, a flashing, a sound proofing material, or an insulation material. The microporous membrane may include at least one thermoplastic polymer, at least one filler, and at least one processing oil. The microporous membrane may be flat or may have ribs. The microporous membrane may include at least one scrim component. A method for forming the microporous membrane is also disclosed.

A building envelope material is comprised of multiple layers, the layers include a substrate facestock, an adhesive layer, and a liner, the liner does not cover the entire surface of the adhesive in efforts to eliminate telescoping when the building envelope material is in a roll form. The removed portion of the liner may include straight coating removals or pattern coating removals.

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 shingle coating asphalt composition is provided that is produced from a paving grade asphalt. The asphalt composition comprises a paving-grade asphalt that has been modified with one or more polymer additives; and a secondary additive comprising one or more of a viscosity reducing agent, a wax, a salt of a fatty acid ester, and an amide of a fatty acid. The shingle coating asphalt coating composition is used to make a shingle. The shingle includes a substrate, the asphalt, and roofing granules.

The invention relates to a construction sheet, in particular sub-roof sheet (1), in particular intended for use as an underlay sheet, preferably formwork sheet, and/or roof seal sheet, and/or facade sheet, with at least one carrier layer (2) designed as fire protection layer and at least one further layer (3), wherein the further layer (3) is designed as a further fire protection layer.

This disclosure relates to an article that includes a nonwoven substrate, a first film supported by the nonwoven substrate, and a second film such that the first film is between the nonwoven substrate and the second film. The first film includes a first polymer and a pore-forming filler. The difference between a surface energy of the first film and a surface energy of the nonwoven substrate is at most about 10 mN/m. The second film includes a second polymer capable of absorbing and desorbing moisture and providing a barrier to aqueous fluids.
