Roof Replacement

You do realize the part of my post you snipped was a joke?

Even with zero roof penetrations you have something like 100 holes in the roof membrane, right?

The roofing material folds down over the side wall, then the trim strip is applied over the roofing material on the side wall..

That is a potential leak that is real and that is where most of the water infiltration happens.. You have at least 40 holes on each side of the roof, not to mention all the holes from the end trim strips..

The cold hard reality with RVs you need to constantly check the caulking on a regular schedule, replace when caulking ages.

It is called "PMs" or Preventative Maintenance.

So in reality, removing all of the holes on top of the roof nets you zero reduction in potential leaks. In fact, I would rather have a leak show up at a roof vent instead of having a hidden leak on the sidewall trim.. That side wall trim can leak for yrs and you will never know it until it pools up and rots out the floor far, far away from the real source of the leak at the trim.

Seen considerable rot damage on both of the trailers I have rehabbed that came from leaks on the side wall trim. Just because that trim has a vinyl cover in place covering the screws, it doesn't mean that water can't leak through. That trim uses and depends on the same butyl rubber caulking and it fails after a couple of yrs.

Absolutely understood, you were joking....that was the point. You made a joke not realizing it would be a great idea.

Yes, you still have to maintain the edges but you can roll those over the exterior where they are more easily visible (think utility trailers). It's easy to claim, you do great maintenance, so it's not an issue but obviously, it is an issue.
