I did not want my vent 'glued' to the roof. I used Mortite brand rope caulk. This is a ribbon of about 5 strands of caulk that works similar to modeling clay. It stops water, conforms to any surface, and is removable in the future. I love this stuff as it is easy to work with and does the job. I used finish washers with the screws and filled the inside of the washers with the caulk. It squeezed out when the screw tightened, completely sealing each screw.
