Is your log home showing signs of water intrusion to the interior, or are the logs showing signs of water staining (i.e., darkening)?  This is a definite potential problem and can lead to interior log core damage that isn’t visible without invasive inspection (i.e., log core drilling).  It may be time for a qualified log home contractor to take a look at whether or not there may be further log (core) damage.  Log damage and repairs can be costly, so it is best to be proactive with maintaining log elements throughout your home; the longer you wait, the worse the issue becomes.
