Wood Gable Vent
There is a nice wood gable vent and from the
outside we can not see if the screen is attached behind it.
Make sure there is some sort of metal screening behind this gable vent while you're inspecting the attic.
This gable vent will not provide adequate ventilation and should be removed and replaced with a solid screen vent.
I would recommend removing the vertical slats and replacing them with quarter inch galvanized screening to allow more air to flow through the attic.
You can see this gable vent restricts the airflow and could cause moisture problems eventually.
