Just had mine pull out, you will need to remove all the old caulking, unscrew the cap tuck the roof membrane back under the cap, rescrew and caulk the cap. All the screws on mine were broken off. Good Luck
must have been a contagious thing with the 2013's Our gk did it too... but it happened quickly !

This is why I laugh at the 10 year warranty that comes on the roofs. Just a sales pitch! No matter what happens on the roof, when there are problems, the finger is pointed back at the owner.
On this forum we've had people experience screws poking up through the rubber, roofs coming loose, roof decking coming loose and I believe even roof decking missing. I believe the roofs and the suspensions are the weakest parts of the RVs.
