Go after them all
So you have given one example. Why focus on one issue, be it minor, when there are serious other examples to bring up?
What you should do is a drive by of all the other properties in the subdivision that are far worse than this example, and bring them to the meeting on the 15th.
The property in question has to be one of the most well kept in BBF. So they need to do some maintenance on the roof. This problem does not affect others property, and I am sure that they will correct it.
If you want to throw darts, why not put together a list of all the properties that are costing their neighbors money by letting their dandeline seeds infest their yards.
Put up or shut up.
