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 multi-layered thermoplastic roofing membrane comprising a planar body including at least three layers, said at least three layers including (i) a top layer that includes magnesium hydroxide dispersed within a thermoplastic resin, (ii) an upper middle layer disposed below said top layer and including magnesium hydroxide and calcium carbonate dispersed within a thermoplastic resin, and (iii) a lower layer disposed below said upper middle layer and including magnesium hydroxide and calcium carbonate dispersed within a thermoplastic resin.

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.

A method of installing a roof system includes providing a first membrane composite; adhesively securing the first membrane composite to a roof surface through a UV-cured pressure-sensitive adhesive layer; providing a second membrane composite; adhesively securing the second membrane composite to the roof surface through a UV-cured pressure-sensitive adhesive layer, where the second membrane composite is positioned adjacent to and partially overlapping a lap area of the first membrane composite; and adhesively securing the second membrane composite to a first planar surface of the first membrane composite along a primer layer through the UV-cured pressure-sensitive adhesive layer disposed on the second membrane composite.

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.
