  • Can this be stuck down using bitumin to a nailed down felt roof sheet?

    Yes this has a bitumen skirt so you could stick it down using bitumen.

  • Do you need any sealant or adhesive to fix the vent to a bitumen roof? Or does the skirt have some sort of adhesive on it?

    Please see the datasheet in the related documents for further information. 

    The skirt will need to be adhered, or torched onto the roof.
