A roofing device is described for attaching a roofing membrane to a roof having a curb or a parapet wall comprising a cap flashing, a top flange connected to the cap flashing and extending outward therefrom, a wall flange extending downward from the top flange. The wall flange and the top flange defining a filler channel with the curb when the cap flashing is attached to the curb. A drip edge flange extends outward from the wall flange. The roofing membrane is wrapped over an elongated resilient filler piece which is snugly inserted into the filler channel. A plurality of tabs integral with the wall flange and co-terminus with the drip edge flange, are bent towards the curb securing the filler piece and roofing membrane in the filler channel. The tabs have a tab flange which extend outward at an angle away from the curb allowing for ease of unbending the tabs to remove the filler piece when repairing or replacing the roofing membrane. Also described is a pre-manufactured roofing device including a curb piece for mounting along the perimeter of a roof or roof opening; and a pre-manufactured roofing device of suitable size and shape to be positioned on a curb, and may be manufactured in combination with a fire vent, a hatchway cover hinged to the sealing system to form a complete hatchway, or other roofing product ready for installation.

2. Description of Related Art
The features of the invention believed to be novel and the elements characteristic of the invention are set forth with particularity in the appended claims. The figures are for illustration purposes only and are not drawn to scale. The invention itself, however, both as to organization and method of operation, may best be understood by reference to the detailed description which follows taken in conjunction with the accompanying drawings in which:
FIG. 1 is a perspective view of a hatchway for a roof opening including the roofing device of the invention.
FIG. 2 is a cross sectional side view along the lines 3--3 of FIG. 1 of a preferred embodiment of the present invention.
In describing a preferred embodiment of the present invention, reference will be made herein to FIGS. 1-3 of the drawings in which like numerals refer to like features of the invention. Features of the invention are not necessarily shown to scale in the drawings.
FIG. 1 shows a perspective view of a hatchway 12 for a roof opening 17 incorporating the roofing device 2 of the present invention. The hatchway 12 comprises a hatchway cover 5 conventionally hinged along a hinge line 8 to the roofing device 2.
A preferred embodiment of the roofing mechanism of the present invention is generally referred to with reference numeral 2. The roofing mechanism is positioned on top of a curb 20 which surrounds the perimeter of the roof opening or is part of the parapet wall of a roof. The curb 20 prevents snow and rain, which may accumulate on the roof, from entering the roof opening or getting underneath the roofing membrane 1.
