ABSTRACT:
A sealing system is shown for sealing between a waterproof roofing membrane and a curb around a roof opening, including a cap flashing for the curb, a top flange connected to the cap flashing and extending outwardly therefrom and a wall flange connected to the top flange which extends downwardly and forms a filler channel defined by the top flange, the wall flange and the curb. The roofing membrane is held in the filler channel by folding it over a longitudinal resilient filler material sized to fit closely within the filler channel. A plurality of spaced-apart tabs integral with the wall flange are bent into the filler channel beneath the filler material to securely hold the membrane therein without the necessity for any loose fasteners. A preassembled sealing system perimeter frame ready for mounting on an existing curb, a sealing system with an attached hatchway cover, and a complete hatchway with perimeter frame sealing system, cover, curb and associated flashing are also disclosed.
