Ours is the same. Mainly at the seams of the roof decking, but there are others. Cedar Creek says this is "normal". Not to me it isn't as we've had several that did not get any bubbles or wrinkles. Either way, it doesn't affect the function of the roof. It just doesn't look great. Ours too changes with the weather conditions. Some days it looks great, other days you see the wrinkles / bubbles.

At least in Heaven, RVs will be perfect, and I won't have to keep fixing them.
