New Roof Leaking? Your Rights and Next Steps in Michigan

A stain spreading across a ceiling under a roof that was installed last fall is one of the worst feelings in homeownership, and the instinct to panic is understandable. Try to set that aside for a moment, because the situation is usually more manageable than it feels. New-roof leaks almost always trace back to a specific installation detail rather than a defective batch of shingles, and a legitimate installer stands behind their work with a workmanship warranty precisely because this happens occasionally, even on well-run jobs. It does not mean the crew did sloppy work across the board, and it almost never means the whole roof has to come off again. This guide walks through why it happens, what to document in the first two days, what a reasonable contractor response looks like, the real difference between a warranty callback and a claim against a contractor who has vanished, and where a second opinion belongs if the installer is slow, defensive, or gone.

01 / THE SHORT ANSWERWhat to do right now

Photograph the interior damage, note the date and the weather at onset, and put your installing contractor on written notice today, by email or text, referencing your contract or invoice number. Do not climb onto the roof yourself. Almost every reputable installer includes a workmanship warranty separate from the shingle manufacturer's materials warranty, and a leak reported promptly and in writing is usually addressed at no charge if the cause traces back to the install. The sections below cover the likely cause, the documentation that protects you, and what counts as a fair timeline for a response.

02 / THE LIKELY CAUSESWhy new roofs occasionally leak

A shingle field itself rarely fails at a few months old. When a new roof leaks, the water almost always found its way in through a detail, a seam, a tie-in, or a penetration, rather than through the shingles themselves. Knowing which category applies to your leak helps you have a more productive first call with your installer.

Flashing and tie-in details

Every place a roof meets something else, a chimney, a sidewall, a valley, a dormer, is finished with flashing rather than shingles alone, and that flashing is formed and fitted by hand on site. A step-flashing course tucked one course short, a chimney counter-flashing reglet not sealed evenly, or a valley metal lapped the wrong direction can all let water in during a hard rain even though the field of shingles around it looks perfect from the ground. Because these details are cut and bent to fit a specific roof rather than dropped in from a box, they are the part of the job most sensitive to an individual crew member's care that day. This is the single most common source of a leak on an otherwise new roof, and it is squarely a workmanship item, not a materials problem.

Penetrations and add-on mounts

Pipe boots, vent stacks, and any hardware mounted through the roof after the fact, a satellite dish, an antenna bracket, a solar attachment, are all places where a fastener or a seal has to do the work a shingle alone cannot. A pipe boot that was not seated fully under the course above it, or one that was nicked during install, can leak in a way that only shows up after a few freeze-thaw cycles have worked at the rubber. If another trade, a satellite installer or an HVAC tech, drilled through your new roof to mount equipment after the roofers left, that penetration was never part of the roofing warranty in the first place, and it is worth asking directly whether anything has been installed on the roof since the crew finished, since that single question resolves a surprising share of these calls.

Condensation masquerading as a leak

Not every ceiling stain is a roof leak at all. Attic condensation, caused by warm moist household air reaching a cold underside of the roof deck, can drip and stain a ceiling in a pattern that looks exactly like a leak, especially in winter and especially in a newly sealed-up attic with less airflow than the old one had. Homeowners tend to assume the brand-new roof must be the cause simply because the stain appeared soon after the install, when in fact a new roof deck and fresh insulation work can change the attic's airflow enough to expose a condensation issue that was never visible before. This distinction matters because a condensation problem is usually a ventilation or insulation fix, not a roofing defect, and no amount of re-flashing the roof will solve it. An inspector who checks the attic side, not just the shingles, is the only way to tell the two apart, which is one more reason a phone diagnosis is never as reliable as someone actually looking.

Whichever of these applies, the practical takeaway is the same: a new-roof leak is very rarely a sign the whole roof needs to be redone, and it is almost never a materials defect in the shingles themselves. Our companion guide on signs of a bad roof installation goes deeper on the specific defects that predict recurring leaks, if you want to compare what you are seeing against a longer checklist.

03 / DOCUMENT ITThe first 48 hours: what to record

How you handle the first two days shapes how smoothly the rest of this goes, and none of it requires you to get on the roof. A clear, timestamped record turns a he-said, she-said conversation into a straightforward one, and it costs you nothing but a few minutes with your phone.

• Photograph the interior damage as soon as you notice it: the ceiling or wall stain, any active dripping, and a wide shot showing where it sits in the room relative to windows, vents, and exterior walls.
• Note the date, time, and weather at onset, whether it started during or right after rain, wind, or a thaw, since that detail helps narrow down the cause.
• Check the attic if it is safely accessible and photograph the underside of the deck near the stain, but do not go onto the roof itself; that is a job for whoever inspects it.
• Put the leak in writing to your installing contractor the same day, by email or text so there is a timestamp, referencing your contract or invoice number and including your photos.
• Keep every reply, and if the first contact is a phone call, follow it with a short written summary so the notice is documented either way.

That written notice matters more than it might seem. Most workmanship warranties are triggered by notifying the contractor within a reasonable time of discovering the problem, and a dated, written record is the difference between "I called weeks ago and nothing happened" and a documented timeline you can point back to if the response is slow.

04 / A FAIR RESPONSEWhat a reasonable contractor response looks like

A legitimate roofing company treats a callback on a recent install as a priority, not an inconvenience, because a leak this soon reflects on their own work. A fair response generally looks like this: they acknowledge your report promptly, they schedule someone to look at the roof and the attic rather than diagnosing over the phone, they explain what they found in plain terms, and if the cause traces back to the installation, they fix it at no charge under the workmanship warranty. An active, ongoing leak should be treated with more urgency than a stain that appeared once after a single hard rain and has not returned, and a contractor who cannot get someone out within a few days for an active drip, versus a scheduled look at a dry, one-time stain, is worth following up with directly.

What is not reasonable is silence, a contractor who insists the problem must be something else without ever inspecting it, or a repeated pattern of quick patches that do not stop the water for good. A single follow-up patch that does not hold is not unusual on a tricky detail, but the same spot leaking a third time after two claimed fixes is a pattern, not bad luck, and it usually means the underlying cause was never actually found. If your installer has been unresponsive after a documented written notice, or if the same spot leaks again after they claim to have fixed it, that is the point to escalate, either by requesting a second inspection or, if needed, by involving a consumer protection resource.

A workmanship warranty is only as good as the response behind it. A contractor who shows up, explains the cause, and fixes it at no charge is doing exactly what the warranty promises. One who goes quiet is telling you something too.

05 / TWO DIFFERENT PROBLEMSWarranty callback vs. a claim against a contractor who is gone

These are two different situations, and it matters which one you are actually in.

If your installer is still an active, reachable business, this is a straightforward workmanship warranty callback. You notify them in writing, they inspect, and if the cause is theirs, they fix it, generally at no charge to you. This is the situation the section above describes, and it resolves the large majority of new-roof leaks without further steps.

If the installing contractor is out of business, unreachable, or was one of the storm-chasing crews that leave town after a wind event, the picture changes. You may still have a manufacturer's materials warranty on the shingles themselves, and if an enhanced or system warranty was registered at install, it is worth checking whether that program covers any labor at all, which our roof warranties explained guide breaks down in detail. But the workmanship warranty itself generally dies with the company that issued it, since there is no longer anyone bound to honor it. In that scenario, a homeowner is often left paying for the repair out of pocket, and repairs in Macomb County typically run $350 to $3,200, with larger or more complex work running higher. Our guide to what voids a roof warranty is also worth reading here, since it covers steps that can accidentally forfeit coverage you might otherwise still have.

Either way, get everything in writing and keep your contract, your invoice, and any warranty paperwork together in one folder. If the dispute does not resolve through normal channels, a consumer protection complaint or a conversation with an attorney who handles construction matters is the next step, not something to sort out alone over the phone.

06 / THE SECOND OPINIONWhere an independent inspection fits

A second-opinion inspection earns its place in three specific situations: the original installer is slow, defensive, or unreachable; the leak recurs after they claim to have fixed it; or the installer is simply gone and you need an honest diagnosis before spending anything out of pocket. An independent set of eyes documents the roof and the attic as they actually are, separate from whoever installed the roof, which matters if this ever needs to go beyond a phone call.

Our inspection is $0 with no obligation, and it covers the shingle field, the flashing details covered above, the attic side of the deck, and whether what you are seeing is a roofing leak or attic condensation. If the fix is a straightforward flashing or penetration repair, you get a written price, and repairs generally run $350 to $3,200 depending on scope. If the roof needs more than a repair, that assessment comes with photos, not a guess. You can start from the instant estimator or call directly, and if you would rather see the full published price canon first, our cost calculator and pricing page use the same ranges quoted here.

One more thing worth saying plainly: a leak on a new roof is not a verdict on the whole installation. Most of the time it is one detail, found and fixed, and the roof goes back to being exactly what you paid for. Our roof replacement service page covers what a properly installed system looks like from the start, and the broader guides library has the rest of this lane if you want to read further before your inspection.
