DETAILED DESCRIPTION OF THE INVENTION

In addition to the benefits and improvements that the Specification discloses, other objects and advantages that the Specification provides will become apparent from the following description taken in conjunction with the accompanying figures. Although the description discloses and describes detailed embodiments of the present disclosure, the disclosed embodiments are merely illustrative of the disclosure that may be embodied in various forms. In addition, each of the examples given regarding the various embodiments of the disclosure are intended to be illustrative, and not restrictive.

As used herein, the term “roofing material” includes, but is not limited to, roofing membranes, including, e.g., a waterproofing membrane, underlayment, and/or a liquid composition or coating.

As used herein, a “steep slope” roof or roof deck is a roof or roof deck having a pitch of Y/X, where Y and X are in a ratio of 4:12 to 20:12, where Y corresponds to the “rise” of the roof or roof deck, and where X corresponds to the “run” of the roof or roof deck.

As used herein, a “sloped” roof or roof deck is a roof or roof deck having a pitch greater than zero, but the pitch is less than that of a steep slope roof or roof deck.

As used herein, a “flat” roof or roof deck is a roof or roof deck having a pitch of zero.

In some embodiments, the roofing material may be installed on a roof deck. In some embodiments, the roofing material may be installed directly on the roof deck—that is, with no layer or layers between the roofing material and the roof deck. In some embodiments, the roofing material may be installed indirectly on or above the roof deck—that is, with one or more layers between the roofing material and the roof deck.

In some embodiments, the roof deck may be a steep slope roof deck. In some embodiments, the roof deck may be a sloped roof deck. In some embodiments, the roof deck may be a flat roof deck.

According to some embodiments, the invention relates to roofing materials that comprise hybrid membrane systems having, e.g., a substrate layer, a membrane layer, and an adhesive layer. The hybrid membrane systems allow for flexible roofing installation. Typically, liquid coatings for roofing systems and/or membranes require special spray or rolling equipment, and conventional membranes often suffer from intensive labor that is spent around the details. However, according to some embodiments of the invention, a roofing material system is provided that is comprised of a prefabricated membrane for field installation, a self-adhered substrate (e.g., a scrim) for joint connection, and a flashing for joint sealing that allows for fast installation of the same material over all roofing profiles with maximum flexibility. Thus, according to embodiments described herein, a highly flexible, adaptive roofing system is provided that ensures application of a prefabricated membrane over all roofing profiles and details.

One embodiment of this invention pertains to a roll of roofing material that includes a substrate having a first side and a second side opposite to the first side, a membrane layer attached to the first side of the substrate, and an adhesive layer attached to the second side of the substrate, wherein the substrate is exposed on at least a portion of the first side of the substrate, such that at least the membrane layer does not cover the at least a portion of the first side of the substrate that is exposed.

According to the embodiment shown inFIG.6B, the roofing system700further comprises a flashing grade membrane850applied along a space S (or any spaces) between the first roofing material710and the second roofing material810. According to an embodiment, the flashing grade membrane850comprises a fluid flashing material that is applied along the space S between the first roofing material710and the second roofing material810and thereafter cured. According to one embodiment, the fluid flashing material is a viscous material, including, e.g., a UV-curable resin. According to another embodiment, the fluid flashing material is a liquid (e.g., a liquid silicone coating) that can be applied in situ (e.g., in the field) when installing the roofing material.

Some embodiments provide a method of installing a roofing material onto a roofing surface. The method includes (a) obtaining a first roofing material comprising (i) a substrate having a first side and a second side opposite to the first side, (ii) a membrane layer attached to the first side of the substrate, and (iii) an adhesive layer attached to the second side of the substrate, wherein the substrate is exposed on at least a portion of the first side of the substrate, such that at least the membrane layer does not cover the at least a portion of the first side of the substrate that is exposed, (b) obtaining a second roofing material comprising (i) a substrate having a first side and a second side opposite to the first side, (ii) a membrane layer attached to the first side of the substrate, and (iii) an adhesive layer attached to the second side of the substrate, (c) applying the first roofing material to a roof deck, and (d) applying the second roofing material to the roof deck.

In some embodiments, the method further includes applying a separate mesh strip between the first roofing material and the second roofing material, such that (i) the adhesive layer of the first roofing material overlaps the separate mesh strip and (ii) the adhesive layer of the second roofing material overlaps the separate mesh strip (see, e.g.,FIG.6A).

In some embodiments, the method further includes applying a fluid flashing material along any spaces between the first roofing material and the second roofing material to fill any spaces between the first roofing material and the second roofing material by curing the fluid flashing material into a flashing grade membrane (see, e.g.,FIG.6B). According to an embodiment, the applying a fluid flashing material along any spaces between the first roofing material and the second roofing material includes spreading the fluid flashing material on each side of the first roofing material and the second roofing material to create waterproof seals. According to another embodiment, the spreading of the fluid flashing material on each side of the first roofing material and the second roofing material is conducted by spreading the fluid flashing material from 1 inch to 4 inches on each side of the first roofing material and the second roofing material to create the waterproof seals.

According to an embodiment, the applying of a fluid flashing material along any spaces between the first roofing material and the second roofing material to fill any spaces between the first roofing material and the second roofing material, by curing the fluid flashing material into a flashing grade membrane (see, e.g.,FIG.6B), allows for the creation of a monolithic membrane structure (i.e., a structure with no steps and/or discontinuities), while also sealing any seams between the roofing materials, to provide a superior waterproofing membrane structure.

According to the embodiments ofFIGS.4,5,6A and6B, described above, when applied in the field, there are several ways adjacent membranes may be joined, depending on whether either or both of the membranes need to be cut to fit the area. For example, according to the embodiment ofFIG.4described above, when both membranes (i.e., membrane layer316of the first roofing material310and membrane layer416of the second roofing material410) have an extended substrate (e.g., a scrim or mesh) (i.e., first area315A) of substrate312of the first roofing material310and first area415A of substrate412of second roofing material410), the roofing materials310and410will overlap and reside on each other. However, in the embodiment ofFIG.5described above, the second roofing material610was cut and has no extended substrate (e.g., scrim or mesh)612on one side. Thus, in the embodiment ofFIG.5, the first roofing material510with the extended substrate (e.g., a scrim or mesh) (i.e., first area515A) of substrate512of the first roofing material510) will lay on the bottom and the second roofing material610resides on top, such that the adhesive layer618of the second roofing material610will stick to the top surface of the extended substrate of the first roofing material510(i.e., first area515A) of substrate512of the first roofing material510). In yet another embodiment, as discussed above with respect to the embodiment ofFIGS.6A and6B, both membranes716,816or roofing materials710,810were cut and thus have no extended substrate (e.g., a scrim or mesh)712,812on one side. In some embodiments, a separate strip of back adhered mesh (i.e., separate mesh strip840having a substrate (e.g., a scrim or mesh) that is attached to an adhesive layer) was applied onto the bottom and both membranes716,816have their edges residing on this mesh strip (i.e., separate mesh strip840) with their back adhesive layers718,818stuck to this mesh strip (i.e., separate mesh strip840). As discussed above with respect to the embodiment ofFIG.6B, a flashing grade membrane850can be filled into the space(s) S between the neighboring membranes716,816and spread, for example, 1 inch to 4 inches, on each side to create waterproof seals.

A similar approach to the above can be applied to other features or details including, e.g., seams, vertical joints, edges, and penetration profiles. For example, the same or a similar field membrane structure, as described above can be used for pipe treatment.FIGS.7A-7Cillustrate a membrane structure for pipe treatment according to an embodiment of the invention. According to some embodiments, as shown in, e.g.,FIG.7A, a first step of wrapping a substrate912(e.g., a scrim or mesh) with a back adhesive layer918around a pipe900is conducted. According to one embodiment, a complete wrap of the substrate with the back adhesive layer around the pipe can be used to cover the entire pipe circumference, for example, for 4 inches to 12 inches from the bottom of the pipe. In another embodiment, as shown in, e.g.,FIG.7A, the substrate912with the back adhesive layer918can be applied only at the top flashing area914plus a vertical strip915at the expect joint of membrane. In yet another embodiment, and in certain cases when the flashing has sufficient adhesion to the pipe material, the expect joint seam can be less than ¼ inch, so that it can be safely sealed by flashing without reinforcement and thus, a step of wrapping with a substrate (e.g., a scrim or mesh) can be skipped.

According to some embodiments, after the first step of wrapping a substrate912(e.g., a scrim or mesh) with a back adhesive layer918around a pipe900(e.g.,FIG.7A), a second step of cutting a piece of field membrane916is conducted to wrap the membrane916around the pipe900, as shown in, e.g.,FIG.7B, with two ends917A,917B of the membrane916meeting at a vertical strip915as described above. In a third step, as shown in, e.g.,FIG.7C, flashing920is used at the top flashing area914and seam915using flashing grade to finish sealing the pipe900.

In some embodiments, joint or penetration treatment can be constructed or partially constructed by extending and bending the field membrane structure. For example,FIG.8is an illustration of a membrane structure for joint or penetration treatment according to an embodiment of the invention. As shown inFIG.8, a substrate1012(e.g., a scrim or mesh) with a back adhesive layer1018is cut, depending on the shape and size of the joint or penetration1000, and wrapped around the joint or penetration1000. As further shown inFIG.8, a piece of field membrane1016is cut and the membrane1016is bent and/or wrapped around the joint or penetration1000in any orientation needed to treat the joint or penetration1000. According to an embodiment, any seam between neighboring membranes can be filled by flashing grade membranes (not shown).
