When I changed two of our roof vents over to Thule Omnivent fan units I bedded the new roof vents down on SikaLastomer 710 which is a non-setting butyl sealant.

SikaLastomer®-710

SikaLastomer®-710 is a butyl based pasty and non-sagging sealant which contains solvents. The curing takes place by physical drying. This product can be used for the plastic sealing of joints in many industrial sectors.
