As a follow up to this question, I have two 54' x 3 " gaps running the length of an overhang in my roof supposedly for venting. I believe these to be the point of entry for some squirrels and who knows what else. I bought the house as a foreclosure, and when I asked the housing inspector about it, he indicated they were by design for "venting." At the time I thought, great no rodent on my roof will have a hard time getting in there. Turns out that was true. Would covering these with a screen be the best course of action for preventing entry? I feel like that would barely slow them down.
What is the best way to seal this? I would try running the length with sub-flooring, but that seems like it would exclude the "venting" idea if that is in fact needed.
If screen is the best choice, is there a material, grade, mesh, and/or thickness that would be recommended?
Is this on the money when it recommends:
The use of ½-inch x ½-inch screen is a reasonable compromise between ventilation requirements and rodent control.
