Abstract: A conduit housing for enclosing the juncture between a roof and an elongated conduit such as flexible cable or a pipe extending upwardly through the roof is disclosed. The housing may be installed while the conduit remains in situ and without disconnecting the conduit from an external utility to which it is connected. The housing includes first and second base sections, a hood, and a conduit opening extending through a side wall of the housing. The base sections are slidably engageable with each other around the conduit on the roof to form a base assembly. The base assembly has an open top and extends peripherally around an interior region containing a lower portion of the conduit. The hood is engageable with the base assembly to cover at least the open top of the base assembly. The conduit opening is sized to provide a passage for the conduit from within the interior region to an external region outside the housing, and it may extend through a side wall of the base assembly or a side wall of the hood.

Abstract: Apparatus and a method for extending the length of a vent pipe for a predetermined distance above the elevation of a building roof includes an elongated extension pipe connectable with the vent pipe, a flashing attachable to the roof while fitted as a sleeve over the extension pipe, and a vent cap fittable over the flashing and the extension pipe. The vent cap includes an opening for venting to external atmosphere gases received by the extension pipe from the vent pipe. The extension pipe and the vent cap are sized so as to maintain a venting pressure in the extension pipe not greater than the venting pressure in the extension pipe.
