2016 Jayco Seneca Roof Cracked

[meyerjohnc]

We have a 2016 Jayco Seneca TS that began leaking around the AC vents in the ceiling. Upon roof inspection, I found the roof was buckled on one side, from the front AC unit to to the large living room slide. The buckled roof is cracked and is raised about .24 inch. Has anyone experience this? No motorhome damage to cause this and no visible buckling of other components. I know I can seal it but am more concerned with ongoing issues.

If you could post a picture that would be very helpful. Is it fiberglass? or what kind of material? Your profile pic shows you off road. I'm not blaming you just wondering if it got overstressed somehow. If fiberglass gets a stress crack started it can keep on going. I understand your underlying concern. I would first make sure the underlying structure is good, then some eternabond tape might be a good fix. But I really feel for ya. It's a real bummer. On edit; it's not uncommon for the air conditioners to be too loose even when they come from the factory new. If that was the case with yours, it may have been possible that the unit was starting to slipn/ slide and started a corner crack which then propagated. Pull the inside grill off and check the four bolts for tightness on both your AC units.

When I was in for service this past May I asked for a factory tour. During the tour, the gentleman explained how foam must be placed in specific areas to prevent the fiberglass roof from cracking. I thought, but did not say, how easily foam could move and then allow the crack. Then there is the issue I am having where the frame may have twisted. This would definitely crack the roof.

The more I learn the more precarious I realize these RVs are.
