The first snowfall of the season is often a welcome sight until you notice water dripping from your ceiling or dark spots forming along the attic rafters.
Winter roof leaks are one of the most frustrating problems Michigan homeowners face, especially because snow and ice can make immediate repair work more challenging.
Fortunately, there are ways to manage the situation safely, prevent further damage, and identify the root cause before it worsens. Here’s a professional roofer’s guide on what to do the moment you discover a leak during the first snowfall.
1. Stay Calm and Locate the Source
When water starts showing up indoors, most homeowners rush to patch it from the inside but this usually only hides the symptom, not the cause.
Instead, begin by tracking where the water is coming from.
- Check your attic first. Bring a flashlight and look for damp insulation, darkened roof decking, or water trails along rafters.
- Avoid climbing the roof during snowfall. Fresh snow and ice make roofs dangerously slick. Wait for professional help before going outside.
- Mark the leak location. Place a small piece of colored tape or make a note in your phone to help your roofer locate it later.
If dripping is active, place a bucket or pan under the leak and move furniture or valuables away. This quick containment step helps limit water damage until the snow can be safely cleared.

2. Relieve Pressure by Letting the Water Drain
If you notice a bulging water spot in the ceiling, that’s trapped water and it could cause the ceiling to collapse. Use a screwdriver or small knife to poke a hole at the lowest point of the bulge, letting water drain into a bucket.
It might sound counterintuitive to puncture your ceiling, but releasing pressure prevents larger sections of drywall from falling and minimizes structural strain.
Just remember: this is only a temporary measure. Once water starts draining, the leak needs to be located and properly sealed as soon as weather allows.
3. Check Common Culprits Behind Winter Leaks
When it comes to leaks during the first snowfall, certain causes appear more frequently than others.
Here’s what professionals at Weather Vane Roofing often find:
a. Ice Dams
An ice dam forms when heat from your attic melts snow on your roof. The melted water flows downward, refreezes along the colder eaves, and creates a barrier that traps water behind it. That trapped water can then seep under shingles and leak indoors.
If your gutters are frozen or you notice thick ice ridges along your roof edge, you likely have an ice dam problem.
You can manage small ice dams by applying calcium chloride in a sock and placing it vertically across the dam to melt channels, but avoid chipping or using rock salt, which can damage roofing materials.

b. Flashing Failure
Flashing thin metal installed around chimneys, vents, and valleys can loosen over time. As snow melts and refreezes, water seeps into even the smallest gaps.
Look for leaks near fireplaces, vent pipes, or skylights; those are telltale flashing issues.
c. Clogged Gutters
When gutters are filled with leaves or ice, melted snow has nowhere to go. It backs up under shingles and causes moisture intrusion along soffits and fascia boards.
Regular gutter cleaning before winter is one of the simplest ways to prevent this.
d. Cracked or Aged Shingles
The freeze-thaw cycle puts enormous stress on old shingles. Even small cracks or missing granules can let water creep in once snow starts melting.
4. Contain and Dry Affected Areas Indoors
Once the leak is under control, focus on preventing secondary water damage like mold and staining.
- Use towels or a wet/dry vacuum to absorb standing water.
- Run fans or a dehumidifier to remove moisture from the air.
- Remove wet insulation from your attic; fiberglass loses effectiveness when soaked and can trap mold spores.
If a leak persists despite drying, the water path may be more extensive than it appears. Remember, water often travels several feet from the entry point before appearing inside your home.
5. Schedule a Professional Roof Inspection ASAP
After containing the problem, call your local roofing professional to perform a thorough inspection once conditions are safe. A trained roofer can assess:
- The exact entry point of the leak
- Condition of underlayment and decking
- Ice dam or gutter issues
- Ventilation and insulation balance
Catching these issues early can prevent thousands of dollars in repairs down the road. The first snowfall is a test run for your roof’s winter readiness. If a leak appears now, larger problems may surface once heavier snow sets in.
It’s why proactive homeowners often book inspections before winter hits. If you haven’t yet, check Why You Should Do a Roof Inspection Before Winter to learn how a pre-season check can prevent these emergencies altogether.
6. Prevent Future Leaks Before Next Snowfall
Managing leaks is reactive, prevention is proactive.
Here are several proven strategies Michigan homeowners can adopt for leak-free winters:
- Improve attic insulation to reduce heat loss that causes ice dams.
- Install proper ventilation to regulate attic temperature and moisture.
- Keep gutters and downspouts clear before temperatures drop.
- Trim overhanging branches that shed snow or scrape shingles.
- Consider a metal roof upgrade if you experience recurring ice dam issues.
If your roof has leaked more than once or shows visible wear, it might be nearing the end of its lifespan. A professional inspection will confirm whether a simple repair or partial replacement is more cost-effective.
