I think I’ve said a version of this before, but cleaning your gutters is one of the most important things you can do for your house. In Oregon, all that the water seems to want to do is get inside especially in our basements and crawlspaces. So either clean those gutters or have them cleaned.
If you have lots of trees you might have to have it done multiple times during a year. While you’re at it, be sure you’re downspouts are properly connected and diverting the water away from your home. It is so common to have water intrusion issues come up when you are buying or selling a home. A little maintenance can avoid some of those issues.
