Maybe you should recommend that you install siding as an option to paint as long as it appears esthetically acceptable. In your example the house has 1 SF of ventilation or is 12 SF short. With those conditions the peeling paint you see is no surprise. This exception can be applied if there is a vapor barrier in the ceiling of the attic. The concept is to stop vapor drive from the interior reducing the need for ventilation.
Interior vapor trapped in the attic can easily be the cause for the peeling paint problem.
Ceiling lights often compromises a vapor barrier in a new house. Therefore, the protection of a vapor barrier does not exist in most homes. This is the way you want to go. This product is well tested by independent laborites and includes many features not offered in other vent systems, yet unbelievably it sells in the same price range.
