Unfortunately, it is all too common. Wrinkles, bubbles, etc. Pretty much just a cosmetic issue, but doesn't hurt the function of the roof membrane. Looks like they weren't too careful when securing the membrane on the side. Mine has some wrinkles where the plywood joints are on the roof, but again, doesn't affect function.
