Ceiling Leak? What to Do Until the Roofer Arrives

What to do when water comes through the ceiling after a storm: shut off power, catch the water, protect your things, stay clear of a bulging ceiling, document it, dry it out, and later seal and paint the stain.

Water coming through the ceiling during or after a storm is stressful, but the first hour matters most. This guide pulls together advice from Home Depot, the Insurance Institute for Business & Home Safety (IBHS), the EPA and Bob Vila on what to do until a licensed roofing contractor can fix the roof, and how to fix the stain once everything is dry. It does not cover getting on the roof. Leave that to a pro.

Stop and call a pro before you start if:

The ceiling is sagging badly, cracking or has already started to fall. Keep everyone out of the room. Bob Vila says a sagging ceiling is a safety hazard that calls for a professional.
Water is coming through a light fixture or reached outlets or the electrical panel. Home Depot says to shut off power at the breaker and not to dry wet wiring by hand. If you can't reach the breaker without standing in water, stay out and call a licensed electrical contractor.
The home is damaged enough that you're not sure it's safe. IBHS says not to enter a damaged home unless local officials say it's safe.
Mold covers more than about 10 square feet. The EPA says you can usually handle mold under about 10 square feet yourself; for more than that, it points to its professional remediation guidance. Our advice: call a professional for mold over about 10 square feet. Florida's mold-licensing law exempts homeowners working on their own home (s. 468.841).
The fix requires getting on the roof. Roof repairs belong to a licensed roofing contractor.

Step by step

Step 1: Shut off power to the area

Home Depot points out that water can pool in light fixtures, which are often the lowest points on a ceiling. Turn off the breaker for that room before you do anything else, and don't touch a wet fixture or outlet. Home Depot also notes that wiring that sat underwater for more than 24 hours, or in water more than a foot deep, will likely need to be replaced, so have an electrician check it.

Step 2: Catch the water

Home Depot says to put a bucket or tarp under an active leak. A bucket with a towel inside cuts down on splashing. Check it often during heavy rain.

Step 3: Move and cover your belongings

Home Depot says to clear the area of furniture and valuables. Move what you can to a dry room, and cover the rest, plus the floor, with plastic sheeting.

Step 4: Stay clear of a bulging or sagging ceiling

If water is pooling above the drywall and the ceiling bulges or sags, keep everyone out from under it and call a pro. Bob Vila calls sagging drywall a safety hazard. Home Depot's guide for contractors mentions making a small hole at the center of a leak to control where the water goes, but a soaked ceiling can come down all at once, so we'd leave that to the person fixing it.

Step 5: Photograph everything

IBHS says to document damage with photos and videos, and to keep receipts for anything you buy or pay for. Photograph the stain with a tape measure in the shot, the water in the bucket, damaged belongings, and the outside of the roof from the ground.

Step 6: Check the attic, if you can do it safely

IBHS recommends checking ceilings for water spots and inspecting the attic for leaks or standing water. Use a flashlight, step only on the framing (the drywall between it won't hold you), and look uphill from the stain for wet wood, dark streaks or soaked insulation. Note what you find for the roofer. Skip this if the attic is very hot or hard to move around in.

Step 7: Stay off the roof and call a licensed roofing contractor

Among Hurricane Ian deaths, Florida's medical examiners listed a Sarasota County man who fell off his roof while installing shutters, and News4Jax reported an 84-year-old Putnam County man who officials believe was pushed over with his ladder by the wind while trying to climb onto his roof. Call a licensed roofing contractor; if the roof will be open for days, ask the roofer to tarp it. IBHS says to cover roof damage while you wait for repairs so more water doesn't get in.

Step 8: Dry it out

The EPA says to dry water-damaged areas and items within 24 to 48 hours to prevent mold growth. Run fans and a dehumidifier, and pull up wet rugs. If the drywall or insulation got soaked, it may need to come out: see how to cut out wet drywall.

Step 9: Once the roof is fixed and the ceiling is dry, seal and paint the stain

Bob Vila's steps for a small, dry stain on solid drywall:

Make sure the cause is fixed. Painting over a stain without fixing the leak just hides an ongoing problem.
Clean it. Bob Vila suggests 1 cup of bleach in 3 cups of warm water, with gloves and goggles, to fade the mark and remove mildew and dirt. The EPA warns never to mix bleach with cleaners that contain ammonia.
Prime with a stain-blocking primer. Regular latex ceiling paint can let the stain bleed through.
Paint. The primed spot will look different, so paint enough of the ceiling to blend it in.

If the drywall is soft, crumbling or sagging, it needs to be cut out and replaced instead.

How long it takes

The EPA's guideline is to dry water-damaged areas and items within 24 to 48 hours. Fix the stain only after the roof is repaired and the ceiling is fully dry; follow the drying times on the primer and paint cans.

Stop and call a pro if you find:

A ceiling that keeps sagging or feels soft over a large area.
Water in light fixtures, outlets or the panel.
Wet insulation across a large part of the attic, or rotted roof decking.
Mold over about 10 square feet, or a musty smell that won't go away.
A stain that comes back after you've primed and painted it. The leak isn't fixed.

Roof repairs must be done by a licensed roofing contractor, who contracts with you directly. Once the roof is fixed, we can handle the ceiling, insulation and paint, matching the texture. See roof leaks and ceiling stains after a storm and the roof leak repair cost guide.

Frequently asked questions

What if my ceiling is bulging with water?

Keep everyone out from under it, turn off power to the room at the breaker, and call a pro. Home Depot's guide for contractors mentions making a small hole to control where the water goes, but a soaked ceiling can come down at once.

How fast do I need to dry a ceiling leak?

The EPA says to dry water-damaged areas and items within 24 to 48 hours to prevent mold growth.

Can I paint over a water stain on the ceiling?

Yes, once the leak is fixed and the ceiling is dry. Bob Vila recommends cleaning it, sealing it with a stain-blocking primer, and then painting, because regular latex paint can let the stain bleed through.

Should I go on the roof to find the leak?

No. Hurricane Ian deaths in Florida included people who fell from roofs and ladders. Check the attic if it's safe, and call a licensed roofing contractor.
