Water-tight double-sided roof patch
View Patent ↗A method for sealing joints formed by the intersection and/or overlap of roofing membranes is disclosed. The method comprises the steps of applying strips of double sided tape to roofing membranes so as to secure the membranes to one another and to fill voids created at the intersection of the membranes. Securing the membranes using double-sided tape creates a tight seal which prevents the seepage of water and debris into the joint. A roof joint patch kit is also disclosed which comprises a roll of roofing membrane and a plurality of double-sided tape strips.
1. A roofing patch system for providing a water-tight seal of roof membranes at T-joints comprising:
a top section of roofing membrane, a bottom-right section of roofing membrane and a bottom-left section of roofing membrane, the top section, the bottom-right section and the bottom-left section each having an upper surface and a lower surface;
a T-joint formed by intersecting the top section, the bottom-right section and the bottom-left section, the T-joint having a vertical seam and a horizontal seam; and
a first strip and a second strip of double-sided tape, the first and second strips having a length, a width, a top and a bottom,
the first strip being positioned beneath the vertical seam with the length of first strip being longitudinally aligned with the vertical seam, and the top of the first strip being in close proximity to the horizontal seam and extending away from the horizontal seam, wherein the second strip bonds the bottom-left and bottom-right sections to one another and assures a tight seal at the vertical seam, and
the length of the second strip being longitudinally aligned with the horizontal seam, the length of the second strip being perpendicular to the length of the first strip, the second strip being positioned beneath the horizontal seam so that the second strip is: (a) secured to the bottom surface of the top section and (b) secured to the upper surface of the bottom-right section and the bottom-left section, wherein the second strip bonds the top section to the bottom-right section and the bottom-left section and assures a tight seal at the horizontal seam.
2. The roofing patch system as claimed in claim 1 further comprising:
a release liner layered on the first and second strips of tape.
3. The roofing patch system as claimed in claim 1 wherein the first and second strips of tape is one of a rectangular, square, circular or oval.
4. The roofing patch system as claimed in claim 1 wherein the length of the first and second strips of tape are in a range from approximately 1 inch to 9 inches.
5. The roofing patch system as claimed in claim 1 wherein the width of the first and second strips of tape are in a range of from approximately 1/2 inch to 4 inches.
6. The roofing patch system as claimed in claim 1 wherein the first and second strips of tape are one of a butyl compound, a single component PVAC water-resistant adhesive, a water-resistant polyvinyl acetate adhesive, a EVA-hot melt adhesive, a pressure sensitive hot melt adhesive atactic polypropylene (APP), a base pressure sensitive tape, a polyurethane adhesive, a thermoplastic adhesive film based with co-polyamides, a thermoplastic adhesive film based with mixed polyolefin and a co-polyamide, an animal base adhesive, an asphaltic base adhesive styrol, a verstat acrylate type adhesive and neoprene rubber cementic base adhesive.
7. The roofing patch system as claimed in claim 1 wherein the roofing membrane is one of thermoplastic olefin, polyvinyl chloride, ethylene propylene diene terpolymer and/or chlorosulfonated polyethylene.
