Yes, happened to us in June this year while passing through Arkansas. First stop we got some duct tape, got ladder out, cleaned and dried the edge of roof, popped it back in and taped it down to finish our trip.
Once home took to local Mack's Camper in Waco, Tx for proper repair.
Lesson learned. Fiberglass roofs require inspection and maintenance. All I have done is wash the roof and check sealants at around holes and caps. Didn't know about needing to clean and redo edges.😢
