Emergency Roof Leaks in Winter: What to Do (and What NOT to Do)

A winter roof leak is stressful because it usually hits fast—wet snow, ice dams, wind-driven rain, and freeze–thaw can force water into places it doesn’t reach in other seasons. Here’s a simple, homeowner-friendly checklist for what to do right now, what to avoid, and how to handle insurance documentation the right way.

Step 1: Protect people first

If water is near lights, outlets, a ceiling fan, or electrical panels:

• Stay out of standing water

• Turn off power to the affected area only if it’s safe to do so

• If you’re unsure, call an electrician or the utility

FEMA specifically warns against touching electrical equipment if you’re wet or standing in water, and to shut off electricity if it’s safe.

Step 2: Stop the interior damage immediately

Do this even before you figure out the roof source:

• Put a bucket under drips

• If you see a ceiling bubble, carefully poke a small hole to drain it into a bucket (prevents a bigger collapse)

• Move furniture and valuables away

• Lay towels/plastic and start gentle water collection

If water is running down a wall, place a towel “wick” into a bucket to guide water downward.

Step 3: Document everything

For insurance and for your own records:

• Take wide photos of each room

• Take close-ups of the stain/drip source, damaged items, and any wet flooring

• Take a short video walkthrough

• Keep notes: date/time, weather conditions, when it started, what you did

Most insurers expect you to document first, then do emergency mitigation to prevent further damage.

Step 4: Call a pro to stabilize the roof (tarp / temporary repair)

In winter, the correct move is often stabilize now, repair properly later:

• Temporary tarping or a small sealed patch

• Targeted clearing around leak zones (valleys, chimneys, roof-to-wall)

• Photos from the roof (helpful for claims and planning permanent repair)

If it’s icy, do not climb up there yourself.

What NOT to do

Don’t climb onto a snowy or icy roof

Even “one quick look” is how homeowners get seriously hurt.

Don’t chop ice off shingles or flashings

This can break shingles, puncture membranes, damage flashing, and create a bigger leak path.

Don’t use open flames or risky heat hacks

Avoid torches, open-flame heaters, or anything that can ignite attic materials.

Don’t run fans/heaters into unsafe electrical conditions

If there’s water near outlets or fixtures, handle power first.

Don’t throw random salt on the roof

Some “melt” products can corrode metals or damage roof components.

Why winter leaks happen

Most February leak calls in Massachusetts come from:

• Ice dams (meltwater backs up under shingles at the eaves)

• Wind-driven rain getting behind flashing

• Valleys and roof transitions where snow packs and refreezes

• Pipe boots / vents where seals crack in cold swings

Mass.gov explains ice dams as a temperature issue: roof deck above freezing while outside is below freezing, with snow present.

Insurance tip: “Emergency mitigation” is good—just keep proof

You generally should:

• Prevent further damage (bucket, tarp, controlled drying)

• Save receipts (tarping, fans/dehumidifiers, materials)

• Keep damaged materials until you’ve documented (or the carrier says discard)

This is consistent with common claim guidance: document → mitigate → track expenses.

Fast checklist you can screenshot

DO:

• Shut off power if water is near electrical (if safe)

• Catch and control water immediately

• Photograph/video everything first

• Call for emergency tarp/stabilization

• Start drying once safe (reduce mold risk)

DON’T:

• Climb a snowy roof

• Chop ice with tools

• Use flames/torches/unsafe heat

• Ignore stains (small leaks become big fast)

Need help now (South Shore MA)

If you’re in Avon, Brockton, Holbrook, Randolph, Halifax, or nearby, send us:

1. a photo of the ceiling stain/drip,

2. exterior shots of the roof line (if safe from the ground),

3. your home height (1/2/3 story).

We can tell you quickly whether this looks like:

• ice dam backup,

• flashing/valley issue,

• or a vent/boot leak—and get you a same-week stabilization option (tarp/temporary repair) when weather allows.
