Serving the Midwest,

A roof leak at 11 p.m. in a February storm is a different situation from a leak on a July afternoon. The roof is icy, the wind is up, the attic is freezing, and the useful decisions are all inside the house. Here is the order to do things in.

The first ten minutes

  1. Move people and valuables out from under it. Electronics, furniture, papers, anything sentimental.
  2. Get containers down and put an old towel in the bottom of each one to stop the splashing. Plastic sheeting or a tarp on the floor saves the carpet and pad.
  3. Cut power to the area at the breaker if water is anywhere near a light fixture, ceiling fan, outlet or panel. Water in a fixture box is a live hazard; do not test it by flipping the switch.
  4. Relieve a bulging ceiling. A sagging, heavy drywall bulge is holding pounds of water and will eventually come down all at once. Standing to the side, out from under it, puncture the lowest point with a screwdriver to let it drain into a bucket in a controlled way. A small hole is a patch; a collapsed ceiling is a room.
  5. Photograph and video everything as it is happening, with timestamps. This matters later.

Then trace it, from the inside

Water rarely enters where it appears. It travels along rafters, along the top of the ceiling drywall and down wall cavities before it finds a place to drop. If it is safe to get into the attic with a flashlight, look uphill from the drip for the wet trail. Note what is above the wet area — a chimney, a vent pipe, a valley, a skylight, a wall intersection — because that detail tells the crew where to start and can save an hour of searching in the dark.

Do not spread insulation around or pull ceiling material down. Photograph what you find and leave it.

What is almost certainly causing it

  • An ice dam. In a winter storm this is the leading cause by a wide margin. Standing water behind a ridge of ice works up under the shingles. Full detail in ice dams and freeze-thaw damage.
  • Wind-driven rain or melt pushed sideways under shingles whose seal strips have been broken by wind.
  • A cracked pipe boot. The rubber collar around a plumbing vent is a very common cold-weather failure.
  • Flashing that has been pried open by freeze-thaw cycling at a chimney or wall.
  • Attic condensation, which is not technically a leak at all — warm moist household air condensing on the cold deck and dripping. If the water appears in several places on a very cold night without heavy precipitation, suspect this.
  • Missing shingles from an earlier wind event that nobody noticed.

What not to do

  • Do not get on the roof. Not to tarp it, not to look, not for a minute. An iced slope at night in wind is how people die doing home repair. See roofing safety.
  • Do not chip at ice on the roof or in the gutters.
  • Do not use a torch, heat gun or open flame on ice anywhere near the roof structure.
  • Do not tear open ceilings beyond the small drain hole; that is remediation work and it affects your claim documentation.
  • Do not throw away wet materials before they are photographed and, ideally, seen by an adjuster.

What an emergency crew can actually do in winter

Honest expectations matter here. In freezing conditions with an active storm, a permanent repair is often not possible — asphalt shingles turn brittle in the cold and sealant strips will not bond properly until temperatures come up. What a crew can do is stop the water: locate the entry point, install temporary protection such as tarping or emergency patching where it is safe to do so, clear ice from a gutter or drainage path where practical, and document the damage thoroughly for your claim. Then the permanent repair gets scheduled for workable weather.

That is not a lesser service; it is the correct sequence. A permanent repair rushed onto a frozen roof at midnight fails, and then you pay for it twice.

The insurance side

Report the loss to your carrier promptly — policies expect prompt notice, and a winter storm is a dated, documented event. Keep receipts for anything you buy to mitigate the damage, such as tarps, buckets, fans or a hotel night if the house is not habitable; mitigation costs are frequently reimbursable. Sudden interior water damage from a storm event is commonly covered, while damage traced to long-term neglect is not, which is exactly why the photographs you take tonight matter. Our claim help page explains how the adjuster visit works.

Why we answer at 2 a.m.

Because water does not wait for business hours, and the difference between a call at midnight and a call at nine the next morning can be a ceiling. John Beal Roofing has run 24/7 emergency service across Missouri, Illinois, Kansas and Indiana since 1947, family-owned and now in the third generation. Holidays included.

Frequently asked questions

What should I do if my roof leaks in the middle of the night?

Move belongings, put containers down, cut power to any circuit near the water, and relieve a bulging ceiling by puncturing its lowest point from the side so it drains in a controlled way. Photograph everything, then call for emergency service. Do not go onto the roof.

Should I poke a hole in a bulging ceiling?

Yes, carefully and from out from under it. A bulge holds pounds of water and can bring the whole ceiling down at once. A small hole at the low point drains it into a bucket and limits the repair to a patch.

Can a roof be repaired during a winter storm?

Emergency stabilization yes, permanent repair usually no. Cold makes shingles brittle and prevents sealant strips from bonding, so crews stop the water with temporary protection and document the damage, then complete the permanent repair when conditions allow.

Is a winter roof leak covered by insurance?

Sudden interior water damage from a storm event is commonly covered, including many ice dam leaks, while damage attributed to long-term neglect generally is not. Report it promptly, photograph everything, and keep receipts for tarps and other mitigation costs.

Why is my roof leaking when it is not even raining?

Two likely reasons: an ice dam melting and releasing water that was trapped behind it, or attic condensation, where warm household air meets the cold roof deck, condenses and drips. The second is a ventilation problem rather than a roof problem.
