Ann Arbor 88 MPH Wind Warning: Storm Damage & Roof Leak Response Guide
Ann Arbor storm damage is the primary concern across Washtenaw County today as 88 mph gusts tear through neighborhoods from Barton Hills to Ypsilanti Township. This guide walks residents through the first hour after the tornado warning ends, what 88 mph winds actually do to a roof, and how to triage a leak without making it worse.

UPDATED APRIL 15, 2026 — active tornado warning for Washtenaw County. The National Weather Service forecast office in White Lake has issued a tornado warning covering Ann Arbor, Ypsilanti, Saline, and surrounding townships with gusts forecast up to 88 mph. Shelter on the lowest interior floor away from windows until the warning expires. This page covers what to do once the storm passes.
Key takeaways for today
- 88 mph gusts exceed the design threshold of most aged asphalt shingles in Washtenaw County.
- Do not climb a wet roof after the warning ends. Triage interior damage first.
- Document water intrusion before moving any contents or pulling wet insulation.
- A wrong tarp creates worse leaks than the original puncture.
- Campus-area renters call the landlord first; owners authorize the contractor.
- Old West Side and Burns Park historic roofs need stabilization now, permitted repairs later.
What 88 MPH Winds Actually Do to a Roof
Uplift is the word that matters. Wind does not push a shingle off a roof — it pulls it.
When an 88 mph gust sweeps across a pitched roof, the air accelerating over the ridge creates a low-pressure zone on the downwind side. That pressure differential pulls upward on every shingle, every piece of ridge cap, and every flashing seam at the same time. The bond holding a shingle down is the factory-applied sealant strip plus four or six nails.
A new three-tab shingle with an intact sealant strip can usually ride out gusts in the 70 to 90 mph range. An eighteen-year-old shingle with a dried-out sealant strip fails at closer to 55 mph. That is the quiet reason older roofs across Ann Arbor and Ypsilanti will take disproportionate damage today even though the gust numbers look survivable on paper.
Ridge caps and flashing go first
Ridge caps sit at the highest wind-exposure point on the entire structure. They fail before the field shingles in most storms. Step flashing around chimneys and sidewalls is the second failure zone because the sealant joint between the flashing and the masonry or siding ages faster than the roof itself. Expect to find leaks tomorrow morning under the chimney, along the ridge, and at the valleys before anywhere else.

The First Hour After the Warning Ends
Work from the inside out. The roof waits until the wind drops.
When the tornado warning expires, the temptation is to step outside and assess the roof. Do the opposite. The first hour is about people, pets, and interior water entry. Outside work can wait until gusts drop under 25 mph and the shingles are no longer a skating rink.
Walk the top floor of the house with a flashlight and look at ceilings. A fresh roof leak shows up first as a darker spot on the drywall or as a faint water ring spreading from a light fixture. If you find one, pull the power to that circuit at the panel before you touch anything near the fixture. Water tracks along wire runs and a wet ceiling box is an energized ceiling box.
Pull attic insulation away from any wet sheathing spot. Saturated fiberglass holds water against the drywall below for hours, and every hour of contact is a new square foot of ruined ceiling. Set buckets under drips, move furniture and electronics out of splash zones, and start photographing. Every photo you take in the first hour is evidence you cannot recreate.
Temporary Tarping: DIY vs Contractor
A badly installed tarp is a funnel, not a seal.
The right moment to tarp a roof is after the gusts drop below 20 mph, after the shingles are dry enough to walk without slipping, and after the forecast says no lightning for the next two hours. Those three conditions rule out most of today for most Washtenaw County addresses.
When a homeowner can do it safely
A one-story ranch, a punctured area under fifty square feet, a dry shingle surface, and a working ladder with a spotter. A heavy-mil blue tarp runs up over the ridge by at least three feet, secured with 1x3 furring strips screwed through the tarp edge into sound decking — not into shingles, which will tear. The ridge overlap is what prevents water tracking under the tarp from the high side.
When it needs to be a contractor
Two stories or more, steep pitch, slate or wood shingle, any structural damage to the decking, a limb-strike hole with splintered rafters, or any condition that puts a homeowner within arm\u2019s reach of a wet roof edge. The math is simple. A fall from a second-story eave ends a weekend faster than any water loss ever will.
A common mistake is tarping the wet spot instead of tarping the source. Water enters at the high point of damage and runs downhill under the shingles before emerging into the attic. A tarp stretched over the stain you can see from inside does nothing if the actual puncture is six feet uphill. This is why the wrong tarp creates a new leak path.
Ann Arbor-Specific Considerations
U-M leases, historic districts, and city debris pickup all affect what you do next.
U-M area rental lease responsibilities
Standard leases from the major campus-area property management companies put structural repair and roof work on the owner, not the tenant. That means a student renter cannot legally authorize a contractor to do anything beyond immediate emergency stabilization. Call the landlord first. Text the landlord second. Email the landlord third. Build the paper trail so that response time is documented.
Historic district emergency repair rules
Ann Arbor has five locally designated historic districts including Old West Side, Division Street, and parts of Burns Park. Emergency stabilization work to stop active water intrusion is permitted without prior Historic District Commission review. Permanent repairs to any visible roof surface are not. Photograph the temporary work, keep the receipts, and call the city planning office the next business day.
City debris pickup and brush
Ann Arbor runs a storm-debris brush pickup program that activates after declared wind events. Brush is stacked at the curb with cut ends facing the street, not bagged. Larger limbs and whole trees are a separate haul-away call. Ypsilanti, Saline, and the townships have their own programs with different rules — check the municipal website for your address before you drag anything to the curb.
Roof Leak to Water Damage Timeline
The clock starts the moment water enters the attic.
Hour 0 to 6. Water enters through the damaged area and soaks the insulation and the top side of the ceiling drywall below. Staining is not yet visible from the living space.
Hour 6 to 24. Staining appears on ceilings. Wet insulation begins compressing under its own weight and loses most of its thermal value. Drywall seams near the wet area begin to sag.
Hour 24 to 48. Sheathing moisture content climbs toward the fiber saturation point. Nail plates on trusses begin to corrode at the contact surface. A bulging ceiling becomes possible.
Hour 48 to 72. The commonly cited mold window opens. In a warm April attic with sun load on the roof deck, visible microbial growth can appear on wet wood within three days. This is why a roof leak in April should not wait a week for a contractor. Our first 24 hours after water damage checklist covers the parallel interior steps in detail.
The longer a leak sits untriaged, the more of the eventual scope shifts from a drying project into a demolition and reconstruction project. Catching it at hour twelve costs a fraction of catching it at hour seventy-two.
Where Provail Actually Comes From
Provail Restoration of Bloomfield is headquartered in Oakland County, not Washtenaw. Our main office is at 4060 W Maple Rd in Bloomfield Township, which is roughly forty-five minutes from downtown Ann Arbor on a normal day and longer when a storm has trees down on M-14 and US-23. We think it matters to say that plainly rather than pretend we have a storefront on Main Street that we do not have.
For Washtenaw County events we dispatch directly from Bloomfield when drive time works, and we coordinate with vetted local subcontractors for immediate stabilization when it does not. The dispatcher on the phone will tell you straight which option fits your address and your timeline. Read our approach to storm damage restoration and water damage restoration for the service scope, and our insurance documentation guide for what to capture before anyone arrives.
Washtenaw Wind Damage FAQ
A tree limb punched through my rental near Central Campus. Who do I call first — my landlord or a contractor?+
Call your landlord or property management company the moment the room is safe and the rain is contained. Most U-M area leases put structural repair on the owner, not the tenant, and the owner has to authorize the restoration contractor. What you can do on your own authority is stop the interior water spread — move electronics off the floor, put down towels, and photograph everything before anything is moved. If your landlord is unreachable and water is actively pouring into a bedroom, document your outreach attempts by text or email so there is a written record.
I live in the Old West Side historic district. Can I start emergency roof repairs without a permit?+
Ann Arbor allows temporary emergency stabilization to stop active water intrusion, but permanent repairs to a roof in a locally designated historic district still need Historic District Commission review. A tarp, temporary plywood over a punctured area, or a short-term patch to stop a leak will generally not draw a violation. Full slate replacement, new ridge caps, or any change to the visible roof line does need approval. When in doubt, call the city planning office the next business day and keep your temporary work photographed and dated.
My roof is leaking into the attic but it is still raining. Should I go up there now?+
No. A wet roof in 50 mph residual gusts is a fall waiting to happen, and lightning in a post-frontal environment is still a risk for another hour after the main cell passes. Work the problem from the inside. Pull insulation away from the wet spot so it does not hold water against the drywall, put a bucket or a shallow tote under the drip, and if a ceiling is bulging from trapped water, clear the room, shut off the circuit, and call a crew — don’t puncture it yourself unless you have a specific plan for where the water is going (see the full roof leak emergency guide at /resources/roof-leak-after-storm-emergency-guide). The roof gets looked at when the wind drops below 20 mph and the shingles dry.
A pole barn on my Saline property lost half its roof. Does my homeowner policy cover it?+
That is a question for your agent, not for a contractor. Outbuilding coverage on a Michigan homeowner policy is usually a percentage of the main-dwelling limit, and the percentage, the exclusions, and the deductible vary by carrier and policy form. Document the barn the same way you would document the house — wide shots, close shots, a walk-through video — and open the conversation with your carrier honestly. This page is not legal or insurance advice.
How long before a wet attic in April turns into a mold problem?+
Warm April attic conditions in southeast Michigan can push a wet sheathing surface past the 48 to 72 hour window that most indoor air guidelines use as a practical threshold for visible microbial growth. Sun load on a south-facing roof deck can warm an attic into the seventies within a day even when the outdoor high is in the fifties. The practical takeaway is that a roof leak in April should not sit for a week waiting for a contractor — either the wet material gets dried or it gets removed.
My tenant in Ypsilanti says the ceiling is leaking. What are my obligations as the landlord?+
Michigan landlord-tenant law requires the owner to keep the premises fit for habitation, which in practice means responding to an active water intrusion quickly, not next week. That is a general description, not legal advice — the specific duties, timelines, and remedies depend on the lease and on local code. Contact a landlord-tenant attorney or the city housing office for anything beyond the immediate stabilization work.
Does Provail Restoration of Bloomfield work in Washtenaw County?+
Yes, on a dispatched basis. We are headquartered in Oakland County and our main crews run out of Bloomfield Township, so for a Washtenaw event we are honest about the drive time and we coordinate with vetted local subcontractors when immediate stabilization cannot wait. Call (248) 531-8404 and the dispatcher will tell you straight whether our own crew, a partner, or a closer option is the right call for your address.
Can I file an insurance claim for a tree that fell from my neighbor’s yard onto my roof?+
In most cases a tree that falls from a neighbor’s yard onto your structure is a claim on your own homeowner policy, not the neighbor’s, unless there is documented prior notice that the tree was dead or dangerous. This is a general pattern and not legal advice. Your carrier and, if needed, an attorney are the right people to untangle the specifics.
