Reason for Birds and Rodents in the Attic

This picture shows a gap between an upper roof section and a lower roof section. The metal is part of the roof flashing on the lower roof. The builder neglected to provide an exterior wall covering between the upper and lower roof sections. Birds and rodents were freely entering the attic causing, damage to the attic insulation and leaving behind droppings. This condition was not discovered until the house was thoroughly inspected.
