Gaskets, vents, etc...

finally got up on the roof to inspect things throroughly, looking for leaks. The vents have been piled high w/ various layers of "stuff"...some of it might be vulkem or other caulk, but there is at least one layer of silicone, too. looks like rather than clean/recaulk, someone decided to just keep piling it on. I mean, the entire flange around each vent is completely covered with goo...couple inches wide. what a mess! I don't know what they were thinking, whomever did this..maybe they thought it necessary to cover all the rivets (?) I don't know...but its a mess.

I noticed that there is a gasket between the vent flange and the skin of the trailer. it sticks out from the flange about 1/16th of an inch....looks old. wondering if this should be replaced, or can I just clean up the mess of old caulk, and put a neat bead of vulkem around the vent.

Same thing w/ the refer vent, and the range-exhaust-hood vent: is there a special gasket that should be replaced before caulking? I know there are special one's for the plumbing vent pipe covers.

If it REALLY needs to be replaced, I'll probably have to wait 'till spring. many, many rivets around the ceiling vents...looks like a big project, and I've got other things to work on right now. although, I don't want any leaks to damage my trailer, either. just wondering if there is a temporary fix that'll get through the winter months, until I can get some more time in the spring. (duct tape? plastic sheeting? just temporary...not going anywhere w/ the trailer for a while).

Vent Gaskets replacement...

From InlandRV in another post using their kit...

Installation instructions are very basic.
1. Clean up the old residue.
2. Place the fiberglass screening over the vent pipe.
3. Place the gasket over the vent pipe and firmly push it down so that it is flat with the roof.
4. Apply "vulkem" sealer from the inner edge of the hole in the gasket, forcing it through the fiberglass screening, and onto the black pipe. That gives the installation a positive seal.
5. Reinstall the polished vent pipe cover.
6. Apply a small bead of "vulkem" sealer around the base of the cover.
7. Your done. Have a cool one, sit back, and admire your work.
8. Repeat as necessary (the cool one or another gasket, or both).

yep, I've seen this thread... thanks. I'm referring to the big square crank-up vents that ventilate the interior of the trailer. what about those?
