Bailey Unicorn Madrid - Paint peeling on roof

We have a Bailey Unicorn Madrid - 2011 model.We've used it for 2 seasons now and cleaning the roof this week, before putting it back into storage, has identified that the paint is peeling all around the main forward roof light and part of the centre roof light. The paint has peeled in a narrow strip at the edges of the rooflight and where some green mould was present. I'm currently awaiting advice from the dealer as to what action is possible under the warranty. Has anyone else had this problem?
