Some embodiments of the present disclosure relate to roofing composites. In some embodiments, the roofing composite includes a first layer having a top surface. In some embodiments, the top surface of the first layer comprises a first embossed surface portion, a second embossed surface portion, and a flat surface portion between the first and second embossed surface portions. In some embodiments, the flat surface portion is between the first and second embossed surface portions. In some embodiments, the roofing composite is configured to attach to a roof structure, such as a roof deck. Methods of forming roofing composited are also disclosed.

Roof covering (I) for flat roofs, comprises (A) a polymeric sealing layer and (C) a self-adhesive layer, separated by a soft elastomeric intermediate layer (B).

A method for applying a roofing membrane may include unrolling an adhesive material onto a roofing board to adhere a bottom surface of the adhesive material to the roofing board. The method may include removing a release liner from the adhesive material to expose a top surface of the adhesive material. The method may include applying a roofing membrane to the exposed top surface of the adhesive material to adhere the roofing membrane to the roofing board.

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.

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.

In some embodiments, roofing systems and methods thereof are disclosed. In some embodiments, the roofing system includes a roofing substrate comprising concrete and a top surface. In some embodiments, the roofing system includes a roofing membrane adhered to the roofing substrate. In some embodiments, the roofing system comprises a patterned adhesive on the top surface of the roofing substrate that adheres the roofing membrane to the roofing substrate, that has a spatter pattern, and that comprises a silane-terminated polymer.

A method for covering a roof, the method comprising (i) providing first and second silicone membranes, where the membranes are in the form of rolls; (ii) unrolling the first and second silicone membranes over a roof surface; (iii) positioning first and second membranes adjacent to one another and overlapping and edge of the second over an adjacent edge of the first membrane to thereby form a lap; (iv) securing the first and second membranes to the roof surface; and (v) seaming the first membrane to the second membrane in the lap.
