Abstract

A roofing membrane may include a main body, a first material, and a second material. The first material may be bonded to the main body and positioned toward a first edge thereof. The second material may be bonded to the main body and positioned toward a second edge thereof. The second edge may be positioned opposite the first edge such that the first and second materials are positioned toward opposite edges of the main body. At least one of the first material or the second material may include a first reactive material of a chemically reactive two-part cure system that is configured to chemically react upon contact of the first reactive material with a second reactive material of the chemically reactive two-part cure system.

First claim

What is claimed is:

1. A roofing membrane comprising:
a main body having:
a top surface;
a bottom surface positioned opposite the top surface; and
four edges that define an outer periphery of the main body such that the main body has a rectangular or square profile;

a first material bonded to the main body and positioned toward a first edge thereof, the first material extending along a majority of a length of the first edge;
a second material bonded to the main body and positioned toward a second edge thereof, the second material extending along a majority of a length of the second edge; and
a mechanical fastening component extending along a majority of the length of the first edge and bonded to the first adhesive tape, the mechanical fastening component being a singular component that includes a plurality of holes that are configured to receive a mechanical fastener so as to mechanically fasten the first edge of the roofing membrane to a roof surface.

2. The roofing membrane of claim 1 , wherein the second edge of the roofing membrane is free of a mechanical fastening component.

3. The roofing membrane of claim 1 , further comprising an additional mechanical fastening component extending along the length of the second edge and bonded to the second adhesive tape, the additional mechanical fastening component including one or more holes through which additional mechanical fasteners are inserted so as to mechanically fasten the second edge of the roofing membrane to a roof surface.

4. The roofing membrane of claim 1 , further comprising a releasable liner that is applied atop the mechanical fastening component.

5. The roofing membrane of claim 1 , wherein the first adhesive tape is a singular material that extends along the length of the first edge, and wherein the mechanical fastening component is positioned atop the first adhesive tape.

6. The roofing membrane of claim 1 , wherein the first adhesive tape includes a pair of tape materials that are positioned along the length of the first edge with a gap between the tape materials.

7. The roofing membrane of claim 6 , wherein the mechanical fastening component is positioned within the gap between the pair of tape materials or is applied atop the pair of tape materials.

8. The roofing membrane of claim 6 , wherein the first adhesive tape is bonded to the main body such that an edge of the first adhesive tape is laterally offset from an edge of the main body.

9. The roofing membrane of claim 1 , wherein the roofing membrane is folded in a z-configuration with the folded section of a roofing membrane being disposed between the first adhesive tape and the second material.

10. A roof membrane system comprising:
a first membrane positioned atop a roof, the first membrane having a distal edge that includes a first adhesive tape material on a top surface thereof, the first adhesive tape material extending along a majority of a length of the distal edge;
a second membrane positioned atop the roof and adjacent the first membrane so that a proximal edge of the second membrane overlaps with and is bonded to the distal edge of the first membrane, the proximal edge of the second membrane including a second adhesive tape material on a bottom surface thereof, the second adhesive tape material extending along a majority of a length of the proximal edge; and
a mechanical fastening component positioned between and bonded to the first adhesive tape of the first membrane and the second adhesive tape of the second membrane, the mechanical fastening component including one or more holes through which a mechanical fastener is inserted to mechanically fasten the first membrane and the second membrane atop the roof.

11. The roof membrane system of claim 10 , wherein the first adhesive tape comprises a first reactive material and wherein the second adhesive tape includes a second reactive material, and wherein the first reactive material and the second reactive material are configured to chemically react and cure upon contact with one another to bond the distal edge of the first membrane to the proximal edge of the second membrane.

12. The roof membrane system of claim 10 , wherein the mechanical fastening component includes a polymer or metal material.

13. The roof membrane system of claim 10 , wherein the first adhesive tape is a singular material and the mechanical fastening component is a singular component that is positioned atop the first adhesive tape.

14. The roof membrane system of claim 10 , wherein the first adhesive tape includes a pair of tape materials that are positioned along the distal edge of the first membrane with a gap between the tape materials, and wherein the mechanical fastening components is positioned within the gap between the pair of tape materials or is applied atop the pair of tape materials.

15. The roof membrane system of claim 10 , wherein the first adhesive tape is bonded to the distal edge of the first membrane such that an edge of the first adhesive tape is laterally offset from the distal edge of the first membrane.

16. A roofing membrane comprising:
a main body having:
a top surface;
a bottom surface positioned opposite the top surface; and
four edges that define an outer periphery of the main body such that the main body has a rectangular or square profile;

a first adhesive tape bonded to the main body and positioned toward a first edge thereof, the first adhesive tape extending along a majority of a length of the first edge; and
a mechanical fastening membrane that is adhesively bonded with a top surface of the first adhesive tape, the mechanical fastening member including a plurality of holes that are each configured to receive a mechanical fastener to secure the roofing membrane to a roof surface.

17. The roofing membrane of claim 16 , wherein the roofing membrane further includes a second adhesive tape bonded to the main body and positioned toward a second edge thereof, the second adhesive tape extending along a majority of a length of the second edge.

18. The roofing membrane of claim 17 , wherein the second adhesive tape is free of a mechanical fastening membrane such that the roofing membrane include a single mechanical fastening member.

19. The roofing membrane of claim 16 , wherein the first adhesive tape comprises a pair of adhesive tapes with a mechanical fastening member disposed between the pair of adhesive tapes.

20. The roofing membrane of claim 16 , wherein the first adhesive tape comprises a pair of adhesive tapes that are bonded to the main body and positioned toward the first edge thereof with a gap existing between the inner sides or edges of the pair of adhesive tapes, the gap being sized so that a mechanical fastening member is positionable therein.

21. The roofing membrane of claim 16 , further comprising a releasable liner positioned and removably secured atop the first tape, the releasable liner including at least one scored or perforated region that is independently removable from a main body of the releasable liner.

22. The roofing membrane of claim 21 , wherein the scored or perforated region of the releasable liner is positioned with respect to the main body of the releasable liner so as to aid in alignment of a mechanical fastening member with the first material.
