Have a client who wants to install whirlybird turbines on his house. 5 rib metal. I've installed plenty of these vents on shingle roofs. Can't for the life of me figure out how to do it on metal.
What am I missing here? I'm assuming that I cannot use standard Lomaco Big Whirlys. Is there a product specifically made for this application? A special base that will conform to the ribs in the roofing?
