Roof Edge - 2022 Models

[C&P RV]

We were doing some maintenance a few days ago and I discovered this small cut along the edge of the roof. Our previous rig was a 2014 - 3850FL with a rounded radius along the edge of the roof.

Since I haven't kept up with the evolution of RV roof construction since then, I was really surprised to find what appears to be square aluminum tubing or perhaps just a 90 degree piece of aluminum that may well be part of the frame running along the edge of the roof. It appears to have a smooth finish, but still has an "edge" that the TPO is stretched over.

Having that semi-sharp edge under the stretched TPO creates a real possibility for cuts like this one from barely rubbing even a very flexible section of new tree growth. A close look at the area to the right of the cut shows where the roof was rubbed but not cut. I elected not to patch that (yet) because it felt solid. We have zero recollection of getting anywhere close to a tree at any of the places we've camped since owning it, but there were some low hanging branches we passed under as we went into a couple of COE campgrounds.

It's just an interesting design that seems to be destined to small patches like this one from even a minor rub.

We ended up putting a FlexArmor roof on our 2014 because the entire front section of roof became a giant bubble as we drove down the road at about the 18 month mark of ownership. Hoping I don't have to do that, but I have to say that I've spent the last 6+ years not worrying about my roof when I had the FlexArmor!
