Abstract

According to one embodiment, a roof membrane is provided. The roofing membrane includes a main body, a first adhesive material, and a second adhesive material. The first adhesive material is bonded to a top surface of the main body and positioned toward a first edge thereof. The second adhesive material is bonded to a bottom surface of the main body and positioned toward a second edge thereof. The second edge is positioned opposite the first edge such that the first and second adhesive materials are positioned toward opposite edges of the main body and on opposite surfaces thereof.

First claim

What is claimed is:

1. A roofing membrane comprising:
a main body that is made of a material suitable for installation atop a roof surface for covering and protecting said surface, the main body having:
a top surface;
a bottom surface positioned opposite the top surface; and
four edges that define an outer perimeter of the main body such that the main body has a rectangular or square profile;
a first adhesive tape bonded to the top surface of 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 second adhesive tape bonded to the bottom surface of 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;
wherein the second edge is positioned opposite the first edge such that the first and second adhesive tapes are positioned toward opposite edges of the main body on opposite surfaces thereof, and wherein the first and second adhesive tapes are bonded to the respective surfaces of the main body prior to installation of the roofing membrane on a roof.

2. The roofing membrane of claim 1 , further comprising a membrane material releasably coupled with a top surface of either or both the first adhesive tape or the second adhesive tape to reduce environmental exposure of said adhesive tape.

3. The roofing membrane of claim 1 , wherein a layer of the first adhesive tape has a greater width than a layer of the second adhesive tape atop the respective surfaces of the main body.

4. The roofing membrane of claim 1 , wherein either or both the first adhesive tape or the second adhesive tape are bonded to the respective surfaces of the main body such that an edge of the respective adhesive tape is aligned with the respective first or second edge of the main body.

5. The roofing membrane of claim 1 , wherein either or both the first adhesive tape or the second adhesive tape are bonded to the respective surfaces of the main body such that an edge of the respective adhesive tape extends outwardly of the outer perimeter of the main body from the respective first or second edge of the main body by between about 1/16 and ¼ inch.

6. The roofing membrane of claim 1 , wherein either or both the first adhesive tape or the second adhesive tape are bonded to the respective surfaces of the main body so as to extend along roughly the entire length of the respective first or second edge.

7. The roofing membrane of claim 1 , wherein the material of the main body is ethylene propylene diene monomer rubber (EPDM).

8. The roofing membrane of claim 1 , wherein the material of the main body is Thermoplastic PolyOlefin (TPO).

9. The roofing membrane of claim 1 , further comprising a first membrane material releasable coupled with a top surface of the first adhesive tape and a second membrane material releasably coupled with a top surface of the second adhesive tape.

10. A roofing membrane comprising:
a main body that is made of a material suitable for installation atop a roof surface for covering and protecting said surface, the main body having:
a top surface;
a bottom surface positioned opposite the top surface; and
four edges that define an outer perimeter of the main body such that the main body has a rectangular or square profile;
a first adhesive tape bonded to the top surface of 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 extending outwardly of the outer perimeter of the main body from the first edge by between about 1/16 and ¼ inch; and
a second adhesive tape bonded to the bottom surface of 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 and extending outwardly of the outer perimeter of the main body from the second edge by between about 1/16 and ¼ inch;
wherein the second edge is positioned opposite the first edge such that the first and second adhesive tape are positioned toward opposite edges of the main body on opposite surfaces thereof.

11. The roofing membrane of claim 10 , further comprising a membrane material releasably coupled with a top surface of either or both the first adhesive tape or the second adhesive tape to reduce environmental exposure of said adhesive tape.

12. The roofing membrane of claim 10 , wherein either or both the first adhesive tape or the second adhesive tape are bonded to the respective surfaces of the main body so as to extend along roughly the entire length of the respective first or second edge.

13. The roofing membrane of claim 10 , further comprising a first membrane material releasably coupled with a top surface of the first adhesive tape and a second membrane material releasably coupled with a top surface of the second adhesive tape.

14. A roofing membrane comprising:
a main body that is made of a material suitable for installation atop a roof surface for covering and protecting said surface, the 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 top surface of 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 second adhesive tape bonded to the bottom surface of 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;
wherein the second edge is positioned opposite the first edge such that the first and second adhesive tapes are positioned toward opposite edges of the main body on opposite surfaces thereof, and wherein the first and second adhesive tapes are bonded to the respective surfaces of the main body prior to coupling the roofing membrane with another roofing membrane of similar configuration such that when the roofing membrane is coupled with the other roofing membrane, an adhesive tape on tape coupling is formed.
