Roof seams big problem [message #309479]

My coach sits outside and this summer the alum roof buckled up and lifted the rivets that hold it down (I assume the PO did the rivets). Less bad at the rear but the front lifted up 3/8" all across the roof. It has laid back down now with the cooler weather.
So what can I do now to fix this?
Thanks,

Fred,
Suggest you remove all the rivets and carefully clean the inside surface
without lifting the two surfaces, then inject a good bonding and sealing
urethane and place a hole in the middle and rivet. Work by doing the same
from side to side as the two surfaces will level.
Probably want to drill and rivet about 8" apart, then squeeze the urethane
down in the seam.

Fred,

Give JimB a call about this, he uses a special sealant that is strong yet flexible.
