Abstract:
1. A monolithic spiral design roof pipe flashing, consisting of: a spiraled base having a top surface and a bottom surface; a spiraled boot having an upper perimeter and a lower perimeter; the lower perimeter of the spiraled boot disposed upon the top surface of the base; an annular upper lip disposed upon the upper perimeter of the spiraled boot at an angle relative the base, the upper lip having a raised angular rim, wherein each of the boot and the upper lip define a spiral inner recess, and wherein the upper lip defines a spiral conduit; wherein the base, the boot, and the upper lip have a shared continuous inner edge and a shared continuous outer edge, the inner edge having an inner base edge portion, an inner boot edge portion, and an inner lip edge portion, the inner boot edge portion angularly disposed between the inner base edge portion and the inner lip edge portion, the inner boot edge portion and the inner lip edge portion disposed within the inner recess, the outer edge having an outer base edge portion, an outer boot edge portion, and an outer lip edge portion, the outer boot edge portion disposed between the outer base edge portion and the outer lip edge portion; wherein the outer boot edge portion has a length different from a length of the inner boot edge portion, the angle of the upper lip being determined by a difference in length between the outer boot edge portion and the inner boot edge portion; wherein the base, the boot, and the upper lip further have a shared continuous exterior surface and a shared continuous interior surface, the shared continuous exterior surface and the shared continuous interior surface overlapping at a contact surface; and wherein the base, the boot, and the upper lip are monolithically molded from a single elastomeric hydrophobic polymer substance, the base, the boot, and the upper lip configured to flex from a closed spiral configuration to an open spiral configuration.
