Between April 10 and April 17, Governor Whitmer placed 40 of Michigan’s 83 counties under a state of emergency. The National Weather Service confirmed nine tornadoes statewide, including two EF-1 tornadoes within 15 miles of Canton — one in Van Buren Township on April 4, and another near Belleville in mid-April. Across Wayne County, basements filled with water from sewer backups, overwhelmed sump pumps, and surface runoff. And here’s the part most homeowners are about to learn the hard way: a standard Michigan homeowners insurance policy doesn’t cover any of it.
What Standard Michigan Home Insurance Actually Covers — and What It Doesn’t
Most homeowners assume that if water damages their home, “the insurance” handles it. The truth is more specific. According to guidance issued by the Michigan Department of Insurance and Financial Services on April 17, most homeowners and renters policies in Michigan do not cover flood damage at all. The word “flood” has a very specific meaning in an insurance contract — and it usually means water that enters from outside the home through natural events.
So what about the basement water from last week’s storms? It depends entirely on where the water came from. A sudden, internal source — like a burst pipe — is generally covered. But the most common causes of Michigan basement flooding aren’t covered under a standard policy:
- Sewer or drain backup (the city’s sewer overflows into your home)
- Sump pump failure or sump pump overflow
- Surface water entering through doors, windows, or foundation cracks
- Snowmelt runoff or rising groundwater
- Overflowing rivers or creeks
Every one of those was happening in Wayne County this month. None of them are covered automatically.
The Three Types of Water Coverage Most Homeowners Have Never Heard Of
Closing the gap means understanding three separate types of coverage. Each one handles a different kind of water event, and most Michigan homeowners have none of them.
1. Water Backup Endorsement. This is the rider that covers water backing up through drains, sewer lines, toilets, or a failed sump pump. According to industry data, water backup endorsements typically cost between $50 and $250 per year, while the average sewage backup claim runs $3,000 to $15,000. For most Canton-area homeowners with a finished basement, this is the single most important coverage gap to close. It is not included in any standard policy. You have to ask for it.
2. Inland Flood Endorsement. Some carriers — including Auto-Owners Insurance — now offer an Inland Flood endorsement that attaches directly to a homeowners policy. It’s designed for homes in low-to-moderate flood risk areas where traditional flood insurance was historically expensive. Not every carrier offers it, which is one of the practical reasons working with an independent agent matters here.
3. National Flood Insurance Program (NFIP) Coverage. This is true flood insurance, purchased separately from your homeowners policy. It covers external flooding from rising water — overflowing rivers, storm surge, surface flooding. The Insurance Information Institute notes that roughly 25% of NFIP flood claims come from low- to moderate-risk areas, not designated flood zones. One important catch: NFIP policies have a 30-day waiting period before coverage takes effect, so you can’t buy it the day a storm is forecast.
What This Looks Like in Real Life for a Wayne County Homeowner
Picture a Canton family with a finished basement — recreation room, laundry, maybe a guest bedroom. A heavy storm overwhelms the municipal sewer system. Water backs up through the floor drain, and the sump pump can’t keep up with the volume. Two inches of contaminated water across the basement. Drywall has to come out. Carpet, padding, baseboards, the bottom of the furnace, and any stored belongings — gone.
Without a water backup endorsement, that’s an out-of-pocket loss. With one, the cleanup, structural repairs, and personal property damage are typically covered up to the endorsement’s limit. The annual cost of the endorsement is usually less than the cost of replacing one piece of basement furniture.
This is the exact conversation that should be happening at every Michigan home insurance renewal — and very often isn’t. Many policies were written years ago, before the homeowner finished the basement, before municipal sewers in older Wayne County neighborhoods became this overwhelmed, before climate patterns made spring storm events this severe.
What Canton Homeowners Can Actually Do This Week
Three steps, in order:
First, pull out your current policy declarations page and look for the words “water backup,” “sewer backup,” or “sump discharge.” If those words don’t appear, the coverage isn’t there. Don’t assume it is.
Second, think about where water would actually enter your home in a storm. Is it the floor drain? A sump pit? A walkout door? Window wells? The answer determines which combination of coverages — water backup, inland flood, or NFIP — actually fits your house. There’s no universal answer, which is why a five-minute conversation with an agent who knows Wayne County housing stock is more useful than a generic checklist.
Third, get the review done before the next storm, not during it. Water backup endorsements can typically be added at any point, but NFIP flood policies have that 30-day waiting period — meaning the coverage you buy in May won’t help if a storm hits in early June.
A Final Word on Storm-Damage Scams
DIFS issued a specific fraud warning on April 17 about door-to-door contractors and adjusters targeting homes with storm damage across Michigan. The Department’s recommendation is direct: contact your insurance company before hiring any contractor. Insurance adjusters paid by your carrier should never ask you for money. If someone shows up at your door this week, the smart move is to pause and call your agent first.
Take the Next Step
Tucker Insurance Agency has been having this exact conversation with Southeast Michigan families since 1970. As an independent agency, we work across multiple top-rated carriers — including Auto-Owners and Progressive — to compare water backup endorsements, inland flood options, and NFIP coverage side by side. There’s no obligation, and it costs nothing to compare. If you’re not sure what’s actually on your policy, or if your renewal arrived with a number you weren’t expecting, a quick call can sort it out before the next storm.
