yep, thats the way to do it. I check the roof every other month or so. My rig is only a year old and I had to caulk 4 different spots that were suspect. Im just glad I got them before I had a leak. Its a contant battle to stay on top of loose screws, caulk and a few other minor things when you own an RV. But most of us agree its worth it in the long run. Plus most of us like to tinker with them anyway.
