Rubber roof concerns

Checked my 2010 crossroads CF31RE Cruiser fifth wheel top yesterday and spots of rubber r releasing from decking. Any one had this problem?

Are you seeing what looks like bubbles under the membrane? If so, I've had numerous bubbles under the membrane on ours seems like forever. None of them have resulted in a problem. A lot of trailer roofs have them.
About the only place I would be concerned about them would be the very front by the edge where it meets the front cap.

Yes that what I am seeing. I need to check where roof meets front cap

I have had a large bubble on the front section of the roof on my rig since new. It is about 10" in diameter and basically round. It sits about 8" back from where the rubber membrane meets the front cap seam. The factory was notified with pictures and they said not to worry about it. In ten years it has not gotten worse or caused any issues.

Join the crowd. I think they all do that. Or at least the ones I’ve owned did.

As a carpenter, I have installed many, many rubber roofs in my day. As stated above, it will not be an issue, unless it is at a spot along the perimeter, where it may have the opportunity to peel, or allow moisture underneath. A common cause of this is the use of excessive adhesive (puddling) in that particular spot, or the rubber was laid before the adhesive was dry enough... The adhesive releases gases as it drys, which will cause bubbling if the roofing is laid too early. Some rubber roofing techniques only require adhesive at the perimeter edges, and seams, and it lays free in the field.
