ABSTRACT:
A device is provided including a pair of base sections adapted to be joined together along a generally vertical plane in approximate alignment with a pipe or other object extending through a roof or supported therein, such sections including a pair of molded plastic-supporting parts and a pair of skirt parts of elastomeric material which have overlapping edge portions and which define a downwardly facing surface secured by an adhesive to the upper surface of roofing material to provide a permanent weathertight seal. A split boot is secured to the upper end of a tubular portion of the base sections and is of a stepped, severable construction for accommodating pipes or other objects of various larger sizes. Lips at the split of the boot are secured together by a channel-shaped metal clip. For smaller objects, a split plug is secured on the upper end of the split boot and has inwardly facing annular serrations for sealing engagement with an object. A multi-purpose adaptor plug is also provided for use with a variety of shapes, sizes and orientations of objects.
