factory vent gasket material May 16, 2017, 11:39:44 am does anyone know what the factory uses for the gasket material (not the lap sealant or the seam cover) for the roof vents? i've been searching, but i've only found references to them "not" using the butyl tape, or other gaskets normally supplied with replacement vents...thanks

They seem like the vents themselves have a fairly limited life and might be expected to be replaced, especially the ones with plastic flanges... Thanks for the info, will select a good poly
