Apparatus and method for sealing a vertical protrusion on a roof
View Patent ↗The present invention is a boot and a method of making a boot for providing a water-tight seal around a protrusion on a roof. The boot may have a top portion adapted to surround a predetermined portion of the protrusion to be covered. The bottom end of the top portion has a bottom opening and a horizontally flat bottom edge. The boot may be installed by placing the bottom opening of the top portion over a protrusion to be covered so that the base portion is substantially flat on the roof. The top opening of the top portion may then be pulled around the protrusion so that it may be adjusted to fit the protrusion. Then the top opening of the top portion may be sealed around the protrusion and the base portion may be sealed to the roofing membrane.
1. An apparatus for covering a protrusion on a roof, said apparatus comprising:
a base portion having an opening;
a top portion attached to said base portion along said opening in said base portion;
a base flap; and
a break in said base portion and said top portion, said break in said base portion separating a first portion of said base portion from a second portion of said base portion, and wherein said break in said top portion separates a first portion of said top portion from a second portion of said top portion,
wherein said break allow said apparatus to be opened to accept a protrusion on the roof to be covered and wherein said first portions of said base portion and said top portion are adapted to be thereafter pulled around to best fit around said protrusion and sealed to said second portions of said base portion and top portion, respectively; and
wherein said base flap covers said first portion of said base portion and said second portion of said base portion when installed around said protrusion.
2. An apparatus according to claim 1 , wherein said base flap extends from a bottom end of said top portion.
3. An apparatus according to claim 1 , wherein said base flap is welded over said first and second portions of said base portion.
4. An apparatus accordingly to claim 1 , wherein said base flap is welded under said first and second portions of said base portion.
5. An apparatus according to claim 1 , wherein said base flap extends from a bottom end of said top portion interposed between said first portion of said base portion and said second portion of said base portion.
