Basically have have a problem in that where the nails meet the wood, you cannot get to the nail hole.  Unless you are willing to try to pry almost all nails up a bit using a pry bar, then placing some silicone caulk at the nail hole, you are going to have to get to the top of the structure.  I would then place a button of silicone caulk on each nail head.  If the problem is vertical support you are in for issues. You may end up having to shore up the vertical supports with sister boards.  If the problem is horizontal support, spread your weight by placing either long 1X6 boards or plywood on the top and then caulk as much as you can.
