After removing the birch ply and insulation from the roof vent area, noticed the seam has a brown stain (see pic). Doesn't appear to be leaking but should I apply vulkem here prior to covering it back up?
On the topic of the roof vent: Also seeking opinions on whether to use the self tapping sheet metal screws with neoprene washers to secure the roof vent?
Does it make sense to add butyl tape to the framing members that the vent screws will be going into as an added layer of waterproofing or is this another spot for vulkem.

I guess no one bit on this thread so I'll go for it...
I don't know what that brown stuff is. Could be some old sealant but It could be some kind of oxidation??? I dunno.
What I do know is that you have all the answers. When in doubt caulk/putty/seal. IT CAN'T HURT! You can't have enough sealant. The point is to use appropriate sealant. We have all seen the trailers that are covered in gobs or silicone or roofing tar.
Every hole/screw/rivet should be sealed on a trailer. Even if you think it couldn't hurt...it won't hurt.
I would buy some aluminum screws if you can. Some metal will react with long contact with aluminum. If you use vulkum in each hole before the screw goes in. Then the screw gets covered with sealant...
