I have something crawling around in my metal roof, maybe a red squirel or a mouse. There's about a 3/4" space between the metal ridge cap and roof panels between the roof panel ridges. I'm looking for advise on what to fill this space with and maintain air flow. I don't think I want to use a disimiliar metal screening. Secondly, I think I need a squirel baffle too on my utility lines biut I'm not sure where to find on. Thanks!
