I've searched through the thousands of "roof seal" posts and have a pretty solid strategy for seams, vents, etc. My issue is with the ladder where it attaches to the roof as well the attachment points of a roof-rail on top of my Allegro. Just about every single screw hole leaks into the interior.
What's the best way to seal the screws and mounting pads for the rail? I see Eternabond sells a caulk. Any other recommendations?
