Apparatus and method for sealing a vertical protrusion on a roof

摘要

The present invention is a boot and a method of making a boot for providing a water-tight seal around a protrusion on a roof. The boot may have a top portion adapted to surround a predetermined portion of the protrusion to be covered. The bottom end of the top portion has a bottom opening and a horizontally flat bottom edge. The boot may be installed by placing the bottom opening of the top portion over a protrusion to be covered so that the base portion is substantially flat on the roof. The top opening of the top portion may then be pulled around the protrusion so that it may be adjusted to fit the protrusion. Then the top opening of the top portion may be sealed around the protrusion and the base portion may be sealed to the roofing membrane.
