Abstract

Some embodiments relate to a roofing accessory. The roofing accessory comprises a protruding member extending from a base member. The base member surrounds at least a portion of an outer edge of a bottom end of the protruding member. The base member has a top surface, a bottom surface opposite the top surface, and an outer edge. The bottom surface of the base member has a weldable portion and an adherable portion between the weldable portion and the outer edge of the bottom end of the protruding member. The roofing accessory comprises an adhesive disposed on the adherable portion of the bottom surface of the base member. The adhesive is not disposed on the weldable portion of the bottom surface of the base member.

First claim

We claim:

1. A roofing accessory comprising:
(a) a protruding member having a top end and a bottom end opposite the top end, with the bottom end of the protruding member having an outer edge; and
(b) a base member surrounding at least a portion of the outer edge of the bottom end of the protruding member, the base member having a top surface, a bottom surface opposite the top surface, and an outer edge,
wherein the bottom surface of the base member consists of an adherable portion including an adhesive and a weldable portion that is free of adhesive, with the adherable portion being between the weldable portion and the outer edge of the bottom end of the protruding member, and
wherein the adherable portion of the base member is configured to adhere to a roofing substrate via the adhesive, and the weldable portion of the base member is configured to attach to the roofing substrate via welding.

2. The roofing accessory according to claim 1 , wherein the adherable portion surrounds at least a portion of the outer edge of the bottom end of the protruding member.

3. The roofing accessory according to claim 1 , wherein the adherable portion is adjacent to the weldable portion.

4. The roofing accessory according to claim 3 , wherein the weldable portion is adjacent to the outer edge of the base member.

5. The roofing accessory according to claim 1 , wherein 10% to 90% of the bottom surface of the base member is the adherable portion.

6. The roofing accessory according to claim 1 , wherein 10% to 90% of the bottom surface of the base member is the weldable portion.

7. The roofing accessory according to claim 1 , wherein the adhesive comprises at least one of an epoxy adhesive, a polyurethane adhesive, an acrylic adhesive, an ultraviolet radiation cured adhesive, a silicone-containing adhesive, a silyl modified polymer, a silane terminated polymer, natural rubber, a neoprene rubber, a polyolefin polymer, a poly-alpha-olefin (APAO/APO) polymer, a polyamide polyvinyl acetate, a poly vinyl acetate, a polyvinyl alcohol, an ethylene vinyl acetate, a styrene, a styrene-isoprene-styrene (SIS) polymer, a styrene-butadiene-styrene (SBS) polymer, a styrene-ethylene/butylene-styrene (SEBS) polymer, a styrene-butadiene rubber (SBR), a polyamide, a polyester, a polyester amide, an ethylene acrylic, a butyl rubber, or any combination thereof.

8. The roofing accessory according to claim 1 , wherein the adhesive has a thickness of 1 mils to 100 mils.

9. The roofing accessory according to claim 1 , further comprising a removable liner.

10. The roofing accessory according to claim 1 , wherein the weldable portion comprises at least one of a thermoplastic polyolefin, a styrenic block copolymer, a polyolefin, a thermoplastic vulcanizate, a thermoplastic elastomer blend, polyvinyl chloride (PVC), or any combination thereof.

11. The roofing accessory according to claim 1 , wherein the protruding member is hollow and does not have a bottom surface.

12. The roofing accessory according to claim 1 , wherein the base member has a circular shape, a rectangular shape, an elliptic shape, a square shape, or a triangular shape.

13. The roofing accessory according to claim 1 , wherein the roofing accessory comprises a vent boot roofing accessory, a split pipe boot roofing accessory, a square tube wrap roofing accessory, a pourable sealer pocket roofing accessory, or a corner roofing accessory.

14. A roofing system comprising:
(a) a roofing substrate; and
(b) a roofing accessory on the roofing substrate, the roofing accessory comprising:
(i) a protruding member having a top end and a bottom end opposite the top end, with the bottom end of the protruding member having an outer edge; and
(ii) a base member surrounding at least a portion of the outer edge of the bottom end of the protruding member, the base member having a top surface, a bottom surface opposite the top surface, and an outer edge,
wherein the bottom surface of the base member consists of an adherable portion including an adhesive and a weldable portion that is free of an adhesive, with the adherable portion being between the weldable portion and the outer edge of the bottom end of the protruding member,
wherein the adhesive adheres the adherable portion of the base member to the roofing substrate, and
wherein at least a portion of the weldable portion of the base member is welded to the roofing substrate.

15. The roofing system according to claim 14 , wherein the adherable portion surrounds at least a portion of the outer edge of the bottom end of the protruding member.

16. The roofing system according to claim 14 , wherein the roofing substrate comprises at least one of a roofing shingle, a polyester, an underlayment, a roofing membrane, a modified bitumen (MODBIT) substrate, a roll good, a pipe, or any combination thereof.
