A through-roof fitting seals a stack with a boot and seals the boot with a gasket around an opening in a sheet roofing created to receive the stack or pipe. An elliptical opening is cut in the roofing sheet. A base plate is placed below the sheet with a central raised portion of the plate extending through the opening cut in the roofing sheet. A flange on the base plate extends outwardly beneath the roofing sheet around the opening. A clamping plate is embedded in a combined boot and gasket so that the gasket extends over the roofing sheet around the opening when an elliptical step in the clamping plate is aligned with the projecting central portion of the base plate. The boot has successively inwardly stepped elliptical portions which terminate in a sloped top with a central opening for receiving and tightly engaging and sealing the pipe or stack. The embedded clamping plate has fastener openings which align with fastener receivers in the base plate. Bosses surrounding the openings extend through the boot to abut heads of elongated fastener bolts which thread into nuts which are pressfit into the fastener receivers in the flange plate. Tightening the fasteners compresses the gasket, sealing the opening in the roofing sheet.

A through-roof fitting for surrounding and sealing a pipe or stack where it extends through a roof, comprising a base plate having a generally oval laterally extended base flange and a generally oval base body extending upward from the base flange for extending the body through a complementary general oval opening in a roofing sheet, and positioning the base flange under the roof around the opening, first fasteners secured in the base body and accessible generally perpendicular to the flange, a clamp plate having a generally oval clamp flange for cooperating with the base flange and having a generally oval clamp body for overlying the base plate body, openings in the clamp body aligned with the first fasteners in the base plate body for receiving fasteners, a molded boot having a boot base for overlying and surrounding the clamp body, the boot base having openings aligned with the openings in the clamp body for receiving fasteners, an integrally formed generally oval boot sleeve connected to an inward edge of the boot base, the sleeve having a relatively long sloping wall at one end of the oval boot base, and a relatively short sloping wall at the other end of the oval boot base, and having a sloping circular boss connected to a top of the boot sleeve, and a large circular opening in the boss for receiving a pipe or stack, a plurality of second complementary fasteners for connecting to the first fasteners, a sealing gasket provided between the clamp flange and the roofing sheet for compressing against the roofing sheet when the first fasteners and second fasteners are joined and tightened, for sealing and preventing leakage around the roofing sheet opening.
