I have added a second bathroom and need to run the exhaust fan through the metal roof. I think most roof vents rely on shingles overlaping the vent flashing to avoid leaks. Since I'm working on a metal roof that does not work. How do I cut through the roof and install a new exhaust vent without creating a leak? I'd appreciate it if somone could direct me to instructions or a product suitable for this application. Thanks.
