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 tape or carrier material bonded to the top surface of the main body and positioned toward a first edge thereof, the first tape or carrier material extending along a majority of a length of the first edge; and
a second tape or carrier material bonded to the bottom surface of the main body and positioned toward a second edge thereof, the second tape or carrier material extending along a majority of a length of the second edge; wherein:
the second edge is positioned opposite the first edge such that the first and second tape or carrier materials are positioned toward opposite edges of the main body,
a first reactive material of a chemically reactive two-part cure system is applied to or soaked in the first tape or carrier material;
a second reactive material of the chemically reactive two-part cure system is applied to or soaked in the second tape or carrier material; and
the first reactive material is configured to chemically react upon contact with the second reactive material and is further configured to not chemically react prior to contact with the second reactive material.

2. The roofing membrane of claim 1 , further comprising a first membrane material releasably coupled with a top surface of the first reactive material and a second membrane material releasably coupled with a top surface of the second reactive material.

3. The roofing membrane of claim 1 , wherein the first reactive material and the second reactive material are resins.

4. The roofing membrane of claim 1 , wherein the first tape or carrier material is bonded to the main body such that an edge of the first tape or carrier material extends outwardly of the outer periphery from an edge of the main body by between about 1/16 and ¼ inch.

5. A roof membrane system comprising:
a first membrane positioned atop the roof, the first membrane having a distal edge that includes a tape or carrier material on a top surface thereof, the tape or carrier material extending along a majority of a length of the distal edge, wherein a of a chemically reactive two-part cure system is applied to or soaked in the tape or carrier material of the first membrane; and
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 tape or carrier material on a bottom surface thereof, the tape or carrier material extending along a majority of a length of the proximal edge, wherein a second reactive material of the chemically reactive two-part cure system is applied to or soaked in the tape or carrier material of the second membrane;
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, and wherein the first reactive material and the second reactive material are configured to not chemically react prior to contact with one another.

6. The roof membrane system of claim 5 , further comprising a first membrane material releasably coupled with a top surface of the first reactive material and a second membrane material releasably coupled with a top surface of the second reactive material.

7. The roof membrane system of claim 5 , wherein the first reactive material and the second reactive material are resins.

8. 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 tape or carrier material bonded to the main body and positioned toward a first edge thereof, the first tape or carrier material extending along a majority of a length of the first edge, wherein a first reactive material of a chemically reactive two-part cure system is applied to or soaked in the first tape or carrier material; and
a second reactive material of the chemically reactive two-part cure system bonded to the main body and positioned toward a second edge thereof, the second reactive material extending along a majority of a length of the second edge; wherein:
the second edge is positioned opposite the first edge such that the first and second materials are positioned toward opposite edges of the main body;
wherein the first tape or carrier material is bonded to the main body such that an edge of the first tape or carrier material extends outwardly of the outer periphery from an edge of the main body by between about 1/16 and ¼ inch; and
the first reactive material is configured to chemically react upon contact with the second reactive material and is further configured to not chemically react prior to contact with the second reactive material.

9. The roofing membrane of claim 8 , wherein the second reactive material is applied as a liquid directly to the roofing membrane surface.

10. The roofing membrane of claim 8 , wherein the second reactive material is applied to or soaked in a second tape or carrier material that is bonded to the main body.

11. The roofing membrane of claim 8 , further comprising a first membrane material releasably coupled with a top surface of the first reactive material and a second membrane material releasably coupled with a top surface of the second reactive material.

12. The roofing membrane of claim 8 , wherein the first reactive material and the second reactive material are resins.
