Abstract

According to one aspect, 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 the top 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 the same surface thereof.

First claim

What is claimed is:

1. A roofing membrane comprising, upon manufacture and before shipment to a job site:
a main body of a roofing membrane material configured for use as an outer surface of a roof, the main body having:
a first surface;
a second surface positioned opposite the first surface; and
four edges that define an outer periphery of the main body such that the main body has a rectangular or square profile; and

a factory-applied adhesive material in the form of a partially-cured butyl tape bonded without the use of a primer to the first or second surface of the main body and positioned toward a first edge thereof, the adhesive material extending along a majority of a length of the first edge.

2. The roofing membrane of claim 1 , further comprising a release liner releasably coupled with a top surface of the adhesive material.

3. The roofing membrane of claim 1 , wherein the adhesive material is bonded to the main body such that an edge of the adhesive material is aligned with the first edge of the main body.

4. The roofing membrane of claim 1 , wherein the adhesive material is bonded to the main body such that an edge of the adhesive material is offset from the first edge of the main body.

5. The roofing membrane of claim 1 , wherein the adhesive material is a first adhesive material in the form of a first partially-cured butyl tape, the roofing membrane further comprising:
a second adhesive material in the form of a second partially-cured butyl tape bonded to the first or second surface of the main body and positioned toward a second edge thereof, the second adhesive 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 adhesive materials are positioned toward opposite edges of the main body.

6. The roofing membrane of claim 5 , wherein the first adhesive material is bonded to the first surface and the second adhesive material is bonded to the second surface.

7. The roofing membrane of claim 5 , wherein the first and second adhesive materials are bonded to the same surface of the membrane.

8. The roofing membrane of claim 5 , wherein a layer of the first adhesive material and a layer of the second adhesive material have approximately the same width on the first surface of the main body.

9. The roofing membrane of claim 5 , wherein a layer of the first adhesive material has a greater width than a layer of the second adhesive material on the first surface of the main body.

10. The roofing membrane of claim 5 , wherein either or both of the first adhesive material and the second adhesive material are bonded to the main body so as to extend along approximately the entire length of the respective edges.

11. A roofing material package, comprising:
a first plurality of first membranes, each first membrane comprising a sheet of a roofing membrane material rolled into a generally cylindrical roll, wherein the roofing membrane material is configured for use as an outer surface of a roof and each first membrane does not include any pre-applied adhesive material; and
a second plurality of second membranes, each second membrane comprising a sheet of the roofing membrane material rolled into a generally cylindrical roll, wherein each second membrane includes a first surface and a second surface opposite the first surface, and a first edge and a second edge opposite the first edge, and wherein each second membrane further includes a first adhesive material bonded to the first surface and positioned toward a first edge thereof, the first adhesive material extending along a majority of a length of the first edge, and wherein each second membrane includes a second adhesive material bonded to the first or second surface of the respective second membrane and positioned toward a second edge thereof, the second adhesive material extending along a majority of a length of the second edge, and wherein a first release liner is releasably coupled with a top surface of the first adhesive material and a second release liner is releasably coupled with a top surface of the second adhesive material;
wherein the first plurality of first membranes and the second plurality of second membranes are packaged for shipment together;
and wherein each of the first and second adhesive materials is in the form of partially-cured butyl tape bonded to the second membranes without the use of a primer.

12. The roofing material package of claim 11 , wherein each second membrane includes the second adhesive material bonded to the first surface of the respective second membrane.

13. The roofing material package of claim 11 , wherein each second membrane includes the second adhesive material bonded to the second surface of the respective second membrane.

14. The roofing material package of claim 11 , wherein the proportions of first membranes and second membranes in the roofing material package are selected to correspond with the proportions of first and second membranes required to cover a particular roof.

15. A method of producing a roofing membrane, the method comprising:
providing a main body of a roofing membrane material configured for use as an outer surface of a roof, the main body having:
a first surface;
a second surface positioned opposite the first surface; and
four edges that define an outer periphery of the main body such that the main body has a rectangular or square profile;

applying an adhesive material in the form of a partially-cured butyl tape bonded without the use of a primer to the first or second surface of the main body and positioned toward a first edge thereof, the adhesive material extending along a majority of a length of the first edge; and
shipping the roofing membrane.
