Base flanges of all BILCO roof hatches and smoke vents can be fabricated with built-in configurations for most brands of metal building roof panels. Our roof hatch curbs for metal roofs and smoke vent curbs for metal roofs offer simplified installation. All metal roof curbs include a built-in self-drainage feature that eliminates water accumulation on the up-slope side.
