ABSTRACT:
A boot provides a water-tight seal around a protrusion on a roof. A top portion thereof surrounds a predetermined portion of the protrusion. A bottom end thereof has a bottom opening and a horizontally flat bottom edge. The top portion may form the boot alone or in combination with a base portion that is connected to the bottom edge. The top portion extends substantially vertically when the base portion resides on the roof. The boot may be open to allow installation on existing protrusions. A top end of the top portion may have a slit running vertically down a predetermined distance thereof to allow the top opening to be adjusted around the protrusion. The boot is installed by placing the bottom opening over the protrusion with the base portion substantially flat on the roof. The top opening is pulled into a fit and sealed around the protrusion.
