Make sure you use a product that’s compatible with the type of roof your coach has.
I like Dicor products as well as Eternabond seam tape. I did the front and rear cap seam with Eternabond when we got our pusher and hope to never worry about leaks in those areas.

Thanks for the reply. The roof is one piece aluminum or sheet metal. Plan is to just coat the perimeter, 4-6” from the edge and around all penetrations, AC, vents, etc. not the entire roof.

What ever you use just make sure not to build product up to high to cause low spots that will become puddles and not let water run off very common problem then sitting water finds is way in

You may laugh, but I just redid the roof of my trailer and used flex seal....that stuff plain works....I got the brush on version but their tape looks like it will work good too...same deal, just the edges all the way around.....

I have wondered about that. Obviously the seam around the outside is where the attention is mostly needed. Build that up, and how does the water get off the roof?
I bought a used trailer that had the seam around the outside failed. I used dicor self leveling caulk. Works well, but seams (no pun) that maybe there is more that should be done.

so far Dicor seems to be the favorite. Others include Eterna bond seam tape, Flex Seal which Chris Gulitti used...

The flex seal seemed to work "for the day" but quickly cracked and leaked pretty soon after using the flex seal. Tried it multiple times in the same spot with flex seal and it just kept cracking after days in the sun and usage of the motorhome.
Finally called a mobile RV repair guy and the stuff he used nearly 2 years ago has kept it sealed. He did remove all other sealants before he did the work. He said the sealer would be available at most RV repair places and stuff was very flexible looking before and after it was applied.
and Henry's Tropi-cool which a friend recommended and is also recomended on RV websites, it is 100% silcone.
