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.

In a device for providing a weather-tight seal on a roof around an object projecting upwardly therefrom, a pair of complementary base sections adapted to be joined together along a generally vertical plane in approximate alignment with said object and together providing an upstanding generally tubular portion for surrounding the object and a peripheral flange portion extending outwardly from the lower end of said tubular portion for engaging the upper surface of roofing material about said object, seal means secured to the upper end of said tubular portion for sealing engagement with said object, each of said complementary base sections including a supporting part of a molded, strong and substantially rigid plastic material and a skirt part of a flexible elastomeric material on said support part, each of said skirt parts having edge portions arranged for overlapping interfitting engagement with edge portions of the skirt part of the other section, said skirt parts having peripheral edge portions together providing a downwardly facing surface adapted to engage an annular portion of the upper surface of roofing material about said object, and an adhesive material for sealing and bonding said downwardly facing surface of said skirt parts to said upper surface of said roofing material.
