Roof Question-What is "normal"
We are looking at a 2003 Travelaire C Class 25'. I should have taken a pic to post but I will try to explain it...While checking the roof I noticed the rubber membrane has two "creases" about 1" high ...

It depends on how the unit is manufactured.
Some have roofs constructed using a sandwich technique these are stronger and usually do not flex as you walk on them.
The manufacturers that use plywood rafters with 3/8 inch plywood sheathing do not intend for the roofs to be walked on except for inspection/ maintenance purposes. These roofs will flex if you don't step where the rafters are located. On these you can use pieces of plywood as stepping stones if you need to be on the roof.
The creases indicate the roofing membrane was not installed properly or has come loose from the adhesive. Only problem I imagine is water may collect along the crease and if you have a crack or hole will help to cause damage.
I would keep an eye on it too see if it gets worse or begins to crack.
