It is Dicor and it is covering a roof seem. The roof of your Airstream is wider than a single sheet on Aluminum. So there is a second smaller piece to complete the roof.

Can anyone tell me what is that strip protecting or what’s its role

Thanks. Would you remove the dicor and replace with Adseal?
I’m trying to figure out what that strip is protecting. Is it dicor sealant ?Attachment 335923
IMO, that is a big gob of caulk that should not be there. (my trailers are 20+ years old and there is none exposed there) When the trailer came from the factory there was no caulking on the surface of that long overlapped metal seam. If it leaks there it would not be normal. If there is actually a leak there it would probably be a loose rivet. A very thin penetrating caulk on the rivets, not the joint, would be better. I've used Acryl R on seams and rivets, but there are other sealants that are thinner and flow more easily that might be better for loose rivets. http://odmrv.com/catalog/index.php?m...oducts_id=1164
If it were me, I would remove all of the caulk along that long line, and not replace it, to see if it actually leaks. (The fans and skylight are more likely leak sources)
If you do decide to replace it, there are better choices than Dicor. My experience has been; Dicor will crack in a year or so due to exposer to UV. (a search will confirm others who have had this same experience) Adseal is a silicone caulk. Since silicone caulk rejects adhesion to itself, any future caulking might be an issue. A urethane caulk with UV resistance would be a better choice, IMO.

It's there because of laziness plain & simple. 👎
My trailer was far from perfect when delivered, and it did have roof vent leaks, but it looked nothing like that.
This was taken last year after cleaning & re-seal.

Don't know what year that seam is on... but its ugly!
Gonna be a bear to scrape off too.
Me, I'd paint the roof white, with the roof paint of your choice...
Double whammy...
1/ Reflects heat and lowers interior temps by 10 t0 20%...
2/ Seals all rivets, joints, etc.
You could spend a week scraping that off if you feel like it, or just paint over it!
