Several part question: I need to install a roof over an existing Flex Core deck. With the existing insulation/ roofing removed, do I need a vapor barrier over the deck before installing Zee purlins? How much insulation/ iso to use? Water/ Ice shield over insulation/ purlins? And will there be thermal trnasfer in the zee in this type of insluation that I would need to worry about? On a retro fit system over flat areas: Clean the ballast off and then add insulation to the flat? Will be creating vertical wall conditions? Is insulation the flat enough? Or do we need batt insulation on the walls? If this is too much or someone has a detailed installation on this type construction, I can be emailed at [email protected]
