초록 ▼

An end tube has an interior and exterior diameter and a length. A central tube has an interior and an exterior diameter and a length. The length of the central tube is greater than the length of the end tube. The exterior diameter of the end tube is essentially equal to the interior diameter of the central tube. An upper portion of the end tube is inserted into and attached to a lower portion of the central tube. In this manner a lower portion of the end tube is adapted to be inserted into a vent pipe of a roof.

1. A roof vent pipe extension system for extending a length of a vertical vent pipe following an application of a second roof over a first roof, the system comprising, in combination: the first roof having an upper surface and a lower surface;the vertical vent pipe extending through the first roof, the vertical vent pipe having a lower end positioned below the first roof, the vertical vent pipe having an upper end located a first distance above the first roof, the vertical vent pipe having an exterior diameter and an interior diameter;the second roof having an upper surface and a lower surface, the second roof applied with the lower surface of the second roof over and attached to the upper surface of the first roof, the second roof having a circular aperture with a diameter equal to the exterior diameter of the vertical vent pipe, the vertical vent pipe extending through the circular aperture of the second roof;an annular bead in contact with the upper end of the vertical vent pipe, the bead being fabricated of a non-slump exterior joint sealant, a solvent-free formulated silyl-terminated polyether;a roof vent pipe extension assembly, the extension assembly including a central tube having ends being a first end and a second end separated by a length of from 15.2 inches to 16.8 inches, the central tube having an interior diameter and an exterior diameter;the extension assembly also including a first end tube and a similarly configured second end tube, the first end tube and the second end tube each having an inner end and an outer end separated by a length of 8 inches to 9 inches out of the central tube and 1 inch to 3 inches inserted into the central tube, each end tube having an interior diameter and an exterior diameter, the exterior diameter of each end tube being slidably received in the vertical vent pipe and the central tube, the inner end of each end tube constituting an unexposed section inserted into one of the ends of the central tube and secured by glue therein to provide an exposed section of 5.7 inches and 6.3 inches respectively, whereby when the exposed section of one of the first and second end tubes is inserted into the vertical vent pipe, the central tube will be in contact with the vertical vent pipe with the interior and exterior diameters of the central tube being equal to the interior and exterior diameters of the vertical vent pipe; andthe central tube being cut to form two extension components, each extension component being formed of one of the end tubes and a portion of the central tube, the extension component having a lower end inserted into the upper end of the vertical vent pipe, the extension component having an upper end spaced above the upper surface of the second roof by a second distance, the second distance being greater than the first distance.
