10. An adjustable roof jack as in claim 1 , wherein said flange is octagonal, circular, square or rectangular shaped.

11. An adjustable roof jack as in claim 1 , said vent cap assembly having a vent cap top that is a square vent cap, round vent cap or wagon vent cap.

12. An adjustable roof jack, said adjustable roof jack comprising:

an octagonal shaped flange;

a first tapered cylinder having a first cylinder top portion and a first cylinder bottom portion, the first cylinder bottom portion fixedly connected to the octagonal shaped flange at a substantially zero degree angle and the first cylinder top portion having two first cylinder folds, one first cylinder fold being a v shaped fold having a first cylinder fold raised portion and a second first cylinder fold being an end slanted l shape and continuous with the one first cylinder fold being a v shaped fold;

a second tapered cylinder having a second cylinder top portion and a second cylinder bottom portion, the second cylinder bottom portion having one second cylinder bottom v shaped fold having a second cylinder bottom fold raised portion and the second cylinder top portion having at least one second cylinder top fold having a second cylinder top fold raised portion, wherein the second cylinder bottom fold is folded over the second first cylinder fold being an end slanted l shape to fixedly and rotationally connect the second tapered cylinder to the first tapered cylinder;

a vent cap tapered cylinder having a vent cap cylinder top portion and a vent cap cylinder bottom portion, the vent cap cylinder bottom portion having at least one vent cap cylinder fold having a vent cap cylinder fold raised portion, wherein the vent cap cylinder fold is folded over the second cylinder top fold raised portion to rotationally connect the vent cap tapered cylinder to the second tapered cylinder; and

a vent cap assembly fixedly attached to the vent cap tapered cylinder top portion.

13. An adjustable roof jack as in claim 12 , further comprising a folded seam along a bottom outside edge of the first cylinder bottom portion and fixedly attached to the octagonal shaped flange.

14. An adjustable roof jack as in claim 12 , wherein at least one of the first cylinder fold, second cylinder bottom fold, second cylinder top fold and vent cap cylinder fold is v shaped.

15. An adjustable roof jack as in claim 12 , wherein at least one of the first cylinder fold and second cylinder top fold is an end slanted l shape.

16. An adjustable roof jack as in claim 12 , wherein said at least one first cylinder fold is two first cylinder folds, one first cylinder fold being a v shaped fold and a second first cylinder fold being an end slanted l shape and continuous with the first cylinder fold.
