With reference to the drawings,
Any or all of the first membrane 510, the second membrane 520, and/or the roofing substrate 530 may be as described herein. For example, as shown in the figure, in accordance with some embodiments of the invention, the first membrane 510 and the second membrane 520 may include cooperating hook-and-loop fasteners (e.g., a hook section on one membrane, and a loop section on the other membrane). In some embodiments, as shown, one or both of the hook section and/or the loop section covers less than an entire surface of membrane.
In some embodiments, the first membrane 510 may include a first one of the hook-and-loop type fasteners 511 (e.g., a hook section), and the second membrane 520 may include a second one of the hook-and-loop type fasteners 521 (e.g., a loop section). In some embodiments, the first membrane 510 may include a first one of the hook-and-loop type fasteners 511 (e.g., a loop section), and the second membrane 520 may include a second one of the hook-and-loop type fasteners 521 (e.g., a section portion). In some embodiments, either or both of the first membrane 510 and/or the second membrane 520 may be thinner at an end thereof, such that an upper surface formed by overlapping the first membrane 510 and the second membrane 520 may be a continuous flat or substantially flat surface.
In some embodiments, as shown in the drawings, the second membrane 520 overlaps the first membrane 510. In some embodiments, the first membrane 510 overlaps the second membrane 520. In some embodiment, one or both of the first membrane 510 and/or the second membrane 520 may be a single-layer membrane. In some embodiment, one or both of the first membrane 510 and/or the second membrane 520 may be a multiple-layer membrane. In some embodiments, the roofing system 500 includes more than two membranes—that is, more that the first membrane 510 and the second membrane 520 installed above the roofing substrate 530.
In some embodiments, after installation of the first membrane 510 and the second membrane 520 above the roofing substrate 530, the hoop-and-loop fasteners are engaged, thereby forming a lap seal between the first membrane 510 and the second membrane 520, as described. As described, in some embodiments, the lap seal is coated with an additional coating, such as, for example, silicone, which is then cured. In some embodiments, the lap seal may be water-resistant, or waterproof, before application of the additional coating. In some embodiments, the lap seal may be water-resistant, or waterproof after application of the additional coating.
As described, in some embodiments, the first membrane 510 and the second membrane 520 are similar roofing membranes, in that each roofing membrane includes a hook section along one edge thereof, and a loop section along an opposite edge thereof.
In some embodiments, the method of installation comprises: obtaining a first membrane, wherein the first membrane comprises a first layer, and a loop section adhered to the first membrane, wherein the loop section covers less than an entire surface of the first layer; obtaining a second membrane, wherein the second membrane comprises a second layer, and a hook section adhered to the second layer, wherein the hook section covers less than an entire surface of the second layer; installing the first membrane above a roofing substrate; installing the second membrane above the roofing substrate; and engaging the hook section of the second membrane and the loop section of first membrane, thereby to form a lap seal between the first membrane and the second membrane.
As discussed above, in some embodiments of the invention, the present invention includes any and all of the membranes, the roofing system including one or more of the membranes installed above the roofing substrate, and/or a method, such as a method of installing the membranes, which comprises obtaining one or more of the components of the roofing system, and installing the components above the roofing substrate, as described.
In some embodiments of the invention, any of the shown and described roofing membranes, and any of the above-discussed variations, may be provided in the form or a roll, in the form of a sheet, or in another form.
Variations, modifications, and alterations to embodiments of the present disclosure described above will make themselves apparent to those skilled in the art. All such variations, modifications, alterations and the like are intended to fall within the spirit and scope of the present disclosure, limited solely by the appended claims.
While several embodiments of the present disclosure have been described, it is understood that these embodiments are illustrative only, and not restrictive, and that many modifications may become apparent to those of ordinary skill in the art. For example, all dimensions discussed herein are provided as examples only, and are intended to be illustrative and not restrictive.
