When Royal Oak Township was built
Royal Oak Township's housing is spread across several decades, peaking in the nineteen-sixties at about 25% of today's homes; a large share of the stock, 42%, predates 1960. These are lower-value homes for the metro, and basements built before the 1960s typically lack the sump pumps, perimeter drain tile, and backwater valves that became standard later, leaving many on their original clay drain tiles.

Why Royal Oak Township homes face basement risk
Basement risk in Royal Oak Township comes down to two things: how old its houses are and the clay beneath them. With a large share of its homes, 42%, built before 1960 and the biggest share going up in the nineteen-sixties, many sit on original clay drain tile, and southeast Michigan's dense clay holds water against those foundations rather than letting it drain. Part of Royal Oak Township sits on combined sewers or drains to a combined-overflow district, so on those blocks sewer backup, not just wall seepage, is the failure mode to plan for first. If a backup has already put water on a floor here, Michigan law leaves a narrow window to file a written claim: how to file a sewer-backup claim in metro Detroit →.

Does insurance cover it?
Often not. Standard Michigan homeowners policies commonly exclude sewer backup and groundwater unless you carry a specific endorsement. Before the next storm, it is worth reading our guide on whether insurance covers sewer backup in Michigan and checking your declarations page.
What to do about it
- Compare your block on the metro map to see how your specific area compares within the community.
- Walk the basement after the next hard rain for dampness, white mineral lines, or a musty smell.
- Extend downspouts and check grading so water flows away from the foundation. More on keeping a basement dry.
