Yep, dirt and decay are minor nuisances, vermin can be a headache, but water is the enemy. I give about 1% of my attention to the sump pump. I don’t trust the float switch, so I put a security camera in there and manually run the pump when the water gets high, and monitor it while on vacation.
Supply hoses for the washing machine get one day closer to failure every 24 hours.
Good luck with the roof! Tending to Maslow Level 1 issues is a good way to satisfy higher-level needs.
