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 method of manufacturing a pre-taped roofing membrane, the method comprising:
providing a main body of the roofing membrane, 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;
providing an adhesive material in the form of a partially-cured butyl tape, wherein providing the adhesive material comprises producing the partially-cured butyl tape by the application of heat to an uncured butyl tape for a time period of less than two months; and
bonding the partially-cured butyl tape to the first surface of the main body and positioned toward a first edge thereof, wherein the partially-cured butyl tape is bonded to the main body of the roofing membrane without the use of a primer and without the use of additional adhesive, the partially-cured butyl tape extending along a majority of a length of the first edge.

2. The method of claim 1 , further comprising aging the combined main body and partially-cured butyl tape to achieve further curing of the partially-cured butyl tape.

3. The method of claim 1 , wherein the partially-cured butyl tape is a first partially-cured butyl tape, the method further comprising:
providing a second adhesive material in the form of a second partially-cured butyl tape; and
bonding the second partially-cured butyl tape to the first surface of the main body and positioned toward a second edge thereof, wherein the second partially-cured butyl tape is bonded to the main body of the roofing membrane without the use of a primer and without the use of additional adhesive, the second partially-cured butyl 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 partially-cured butyl tapes are positioned toward opposite edges of the main body on the same surface thereof.

4. The method of claim 1 , wherein the partially-cured butyl tape is a first partially-cured butyl tape, the method further comprising:
providing a second adhesive material in the form of a second partially-cured butyl tape; and
bonding the second partially-cured butyl tape to the second surface of the main body and positioned toward a second edge thereof, wherein the second partially-cured butyl tape is bonded to the main body of the roofing membrane without the use of a primer and without the use of additional adhesive, the second partially-cured butyl 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 partially-cured butyl tapes are positioned toward opposite edges of the main body on opposite surfaces thereof.

5. The method of claim 1 , wherein the heat is applied until the butyl tape reaches a state of cure equivalent to that achieved by aging an uncured butyl tape for two months to one year.

6. The method of claim 1 , wherein the heat is applied until the butyl tape reaches a state of cure equivalent to that achieved by aging an uncured butyl tape at about 70° F. for two months to one year.

7. A method of manufacturing a pre-taped roofing membrane, the method comprising:
providing a main body of the roofing membrane, 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;
providing an adhesive material in the form of a partially-cured butyl tape, wherein providing the adhesive material comprises producing the partially-cured butyl tape by aging an uncured butyl tape for a time period between two months and one year; and
bonding the partially-cured butyl tape to the first surface of the main body and positioned toward a first edge thereof, wherein the partially-cured butyl tape is bonded to the main body of the roofing membrane without the use of a primer and without the use of additional adhesive, the partially-cured butyl tape extending along a majority of a length of the first edge.

8. The method of claim 7 , wherein aging the uncured butyl tape for a time period between two months and one year comprises aging the uncured butyl tape at about 70° F. for a time period between two months and one year.
