Butene-containing polymer layers for roofing applications are provided. A roofing material comprises a first layer and an adhesive layer. The first layer comprises a thermoplastic polymer. The first layer comprises 0.01% to 35% by weight of a butene-containing polymer based on a total weight of the first layer. When the roofing material is installed on a roofing substrate, the adhesive layer is located between the first layer and the roofing substrate. Related materials, related systems, and related methods, among other things, are also provided.

Butene-containing polymer layers for roofing

Some embodiments relate to a roofing accessory. The roofing accessory comprises a protruding member extending from a base member. The base member surrounds at least a portion of an outer edge of a bottom end of the protruding member. The base member has a top surface, a bottom surface opposite the top surface, and an outer edge. The bottom surface of the base member has a weldable portion and an adherable portion between the weldable portion and the outer edge of the bottom end of the protruding member. The roofing accessory comprises an adhesive disposed on the adherable portion of the bottom surface of the base member. The adhesive is not disposed on the weldable portion of the bottom surface of the base member.

Adherable and weldable roofing accessories and related methods

A roofing composite membrane includes a base layer including a first thermoplastic polyolefin. A weight of the base layer is between 5 and 25 grams per square foot. A coating layer at least partially coats the base layer. The coating layer includes at least one inorganic additive, and a second thermoplastic polyolefin including polypropylene and having a melt flow rate between 0.5 grams per 10 minutes and 12 grams per 10 minutes.

Composite membrane for building applications

Some embodiments relate to a roofing structure. The roofing structure comprises a plurality of roofing membranes positioned on a roofing substrate. Each of the plurality of roofing membranes comprises an edge portion that abuts or overlaps with, or is adjacent to, an edge portion of another roofing membrane, so as to define a plurality of seams between adjacent roofing membranes. The roofing structure further comprises a plurality of standing seam structures positioned over the plurality of seams so as to conceal the plurality of seams.

Roofing structures and related methods

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.

Roofing material with patterned adhesive

Some embodiments of the present disclosure relate to a roofing system. In some embodiments, the roofing system includes a roofing membrane, which may include a cap, a scrim, and a core. In some embodiments, the roofing system may also include an adhesive film, which may include a first adhesive layer adhered to the roofing membrane, a second adhesive layer configured to adhere the roofing membrane to a roofing substrate, and a barrier layer positioned between the first and second adhesive layers. Methods of manufacturing roofing systems are also disclosed.

Roofing systems and related methods

Some embodiments relate to a roofing membrane. The roofing membrane comprises a scrim. The scrim has a top surface and a bottom surface. The roofing membrane comprises a cap layer on the top surface of the scrim. The cap layer comprises a first non-styrenic polypropylene polymer, a first polypropylene impact copolymer, and a first olefin block copolymer. The roofing membrane comprises a core layer on the bottom surface of the scrim. The core layer comprises a second non-styrenic polypropylene polymer, a second polypropylene impact copolymer, and a second olefin block copolymer. The roofing membrane is configured to prevent migration of at least one oil from a layer to the roofing membrane. Some embodiments relate to a roofing structure comprising the roofing membrane, a method for installing the roofing membrane, and the like.

Roofing membranes and related methods

A method includes obtaining a roofing membrane. A first layer of the roofing membrane is applied along a length of a roofing substrate covering a first portion of the roofing substrate. At least a first edge of the first layer is fastened to the roofing substrate. A second layer of the roofing membrane is applied over the first layer along the length of the roofing substrate such that a first edge of the second layer overlies the second edge of the first layer. The first edge of the second layer and the second edge of the first layer are fastened to the roofing substrate using a second fastener in a fastening zone along the length the roofing substrate. The second layer is reoriented such that the second layer overlies the fastening zone and covers a second portion of the roofing substrate adjacent the first portion of the roofing substrate.
