Why Rose Township homes face basement risk

Basement risk in Rose Township comes down to two things: how old its houses are and the clay beneath them. With relatively few of its homes, 19%, built before 1960 and the biggest share going up in the nineteen-nineties, many sit on original clay drain tile, and southeast Michigan's dense clay holds water against those foundations rather than letting it drain.

How Rose Township compares

Rose Township's Index of 22 ranks #81 of 116 communities region-wide and sits below the metro Detroit median of 37. It runs higher than its nearby neighbor Springfield Township.

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

  1. Lower risk is not zero risk on the region's clay soil, a free prevention check takes about 30 minutes.
  2. Watch for symptoms after storms; what you see at your own home matters more than any average.
  3. Maintain gutters and grading, the two cheapest protections any Michigan home has.
