I have an R panel metal roof on my shop. The Jokers that installed the roof originally didn't put the foam closures on the top of the upper end and under the bottom end of the panels. During the install I noticed this and they forced the foam in after the fact. I have had problems with these foam pieces falling out or possibly being helped out, chewed out by roof rats. I probably don't need to describe the mess they make in the shop. I am planning to replace missing foam by pushing it in from the exterior and maybe using some roofing caulk to hold it in. I was wondering if anyone else has suggestions about closing these openings better or rat mitigation in general. I recently built some steel plate and wire rod panel enclosures to put a couple of rat bait stations in out in the landscape. The enclosures are to keep my dog out, he can chew his way into just about anything if he wants to and we have raccoons that could tear a bait station apart and leave it for the dogs. I don't like to put the bait stations in the shop because by the time a rat dies from eating the poison it has left a huge mess. I have some snap traps in the shop but haven't caught a single rat or mouse. Back to the foam closures, I was even considering making a template and routing an aluminum flashing profile to put outside the foam so it is protected from chewing and the harsh Texas sun.
Thanks for any suggestions.
