Roof leaking? What to do first is simple. Keep people away from wet wiring and sagging ceilings. Catch the water. Photograph everything before you clean up. Then call a roofer, and if a storm caused the leak, call your insurer too. Don't climb onto a wet or damaged roof. This guide walks Kansas City homeowners through the first hour. It also covers how to find the source once it's safe, which fixes are reasonable to do yourself, and how to check that an emergency roofer is registered before you sign anything.
Key takeaways
- Safety comes before the ceiling. Don't touch wet electrical equipment, and only shut off power if you can reach the breaker from a dry spot. Stay out from under a sagging ceiling.
- Catch water, then dry fast. Buckets, towels, and plastic sheeting buy you time. The EPA says to dry water-damaged areas within 24 to 48 hours to prevent mold.
- Photograph before you clean or fix. Missouri and Kansas insurance regulators both tell homeowners to document damage, take reasonable temporary steps, and keep receipts.
- Temporary, not permanent. Missouri's regulator warns that permanent repairs made before the insurer inspects can lead to a denied claim. A tarp is a temporary step. A new roof section is not.
- Check the roofer before the price. On the Kansas side, roofers generally need a Kansas Attorney General registration you can confirm. On the Missouri side, check city licensing where it applies.
Before you call anyone, you can see a roofer's registry standing, checked against public records, in our Kansas City roofer directory.
What a roof leak response is (and what it is not)
A roof leak response is everything you do between noticing water and getting a proper repair. It has three jobs: keep people safe, limit the damage inside the house, and keep a record you can use later. It isn't the repair itself. Almost nothing you do from inside the house will stop water coming through the roof. You're managing the damage until someone can fix the cause.
It also isn't proof that the roof is the problem. A wet ceiling can come from a plumbing line, a bathroom fan duct, or condensation on an air conditioning line. Those look like roof leaks and need a different trade. Once the house is safe, figure out which one you have before you pay anyone.
A good response is boring. Turn off what is dangerous, put a bucket down, take photos, write down the time, and make two phone calls. A bad response is dramatic: climbing a wet ladder in the dark, smearing sealant on the wrong spot, or hiring the first truck that knocks after a storm. The first approach costs you an evening. The second can cost you a fall, a denied claim, or a second repair.
Last, it isn't a reason to panic about replacement. Many leaks come from one failed detail on an otherwise sound roof. Whether you need a roof repair or something larger is a question for a qualified roofer on a dry day, not a decision to make while water is dripping.
Safety first: before you touch anything
Electricity and water
Water coming through a ceiling often runs along wiring and light fixtures. FEMA's Ready.gov guidance says not to touch electrical equipment if it is wet or if you are standing in water, and to turn off electricity only if it is safe to do so. The CDC adds that you should turn off main power only from a dry location, and call an electrician if you would have to enter standing water to reach the switch.
In practice: if water is dripping from a light fixture, a ceiling fan, or near outlets, don't use those switches. Turn off that circuit at the panel if the panel area is dry. If it isn't, stay out and call an electrician or your utility.
Sagging or bulging ceilings
A ceiling that bulges downward is holding water. Drywall soaked through can give way. Keep people and pets out from under it. Move what you can from the edges of the room, not from directly beneath. If the bulge is large or growing, leave the room and close the door. Wet ceiling material is heavy, and it isn't worth getting hit to save a rug.
Stay off the roof
Our own request page says it plainly: do not climb onto a damaged roof. Wet shingles, wind, darkness, and storm debris are a bad mix. Everything in the next section can be done from inside the house.
What to do in the first hour: step by step
- Check for electrical hazards. Note where the water is relative to fixtures and outlets. Shut off the affected circuit only from a dry spot, as described above.
- Clear the area under the leak. Move electronics, furniture, rugs, and boxes. Cover what you can't move with plastic sheeting or trash bags.
- Catch the water. Put down a bucket or storage bin with a towel inside to cut splashing. Put towels around it. Empty it before it overflows.
- Take photos and video. Shoot the wet ceiling, the drip, the floor, and anything damaged, before you clean up. Include a wide shot of each room and close-ups.
- Write down the basics. Note the date, the time you noticed it, the weather (hail, wind, heavy rain, snow melt), and which rooms are affected.
- Look in the attic only if it's safe. Use a flashlight, step only on joists or a walkway, and stay clear of wiring. Don't go up if you aren't sure of your footing.
- Call your insurer if a storm was involved. Report the loss and ask what they need from you. More on this below.
- Call a roofer. Ask about emergency availability and whether they do temporary protection, like tarping, before a full assessment.
Contain the water inside the house
Protect belongings and floors
Water moves sideways along joists, trim, and drywall seams, so the wet spot may spread past the drip. Check the room below and nearby closets. Lift rugs off wet floors. Pull books and papers off lower shelves.
Start drying the same day
The EPA's homeowner guide says to dry water-damaged areas and items within 24 to 48 hours to prevent mold growth. Once the drip stops and power is safe, run fans and a dehumidifier. Open interior doors to move air. Wet attic insulation, carpet pad, and soaked drywall often can't dry in that window and may need to be cut out. Photograph those materials before they go in the trash.
Document the leak for insurance
Not every leak is an insurance claim. A DCI spokesperson told Missourinet that most standard policies cover wind and hail, but not wear, tear, and deterioration. Your policy wording controls. Either way, the documentation steps cost nothing and protect your options.
The Missouri Department of Commerce and Insurance advises homeowners to photograph or video damage before beginning cleanup or making repairs, and notes that most policies require reasonable steps to prevent additional damage. Tarping a damaged roof is one of the temporary measures it lists, and it says to keep receipts for emergency repairs. In separate guidance, DCI warns: don't make permanent repairs until your insurance company has inspected the damage, or the claim might be denied.
The Kansas Insurance Department gives similar advice. Its guidance says to take photos before any permanent fixes and track expenses for temporary repairs, since you may be eligible for reimbursement. It also points homeowners to its Homeowners Claim Settlement Checklist.
| What to capture | How | Why it helps |
|---|---|---|
| Interior damage | Wide shot of each room, then close-ups of stains, drips, and bulges | Shows where water entered and how far it spread |
| Damaged belongings | Photos before moving or discarding, plus a written list | Supports a contents claim if your policy covers it |
| Outside view from the ground | Photos of missing shingles, debris, dented gutters, fallen limbs | Ties interior damage to a weather event without anyone climbing |
| Temporary measures | Photos of the tarp, buckets, fans, and dehumidifier in place | Shows you took reasonable steps to limit damage |
| Receipts | Keep tarp, lumber, fan, and dehumidifier receipts, plus any emergency roofer invoice | Both state regulators say to keep these receipts |
| A simple log | Dates, times, weather, who you called, claim number | Keeps the story straight when the adjuster visits |

Temporary tarping: do it safely or wait for a pro
A tarp is the standard temporary measure, and Missouri's regulator names it as one. That doesn't mean you should be the one installing it. Tarping in a storm, on a steep pitch, or on a roof with broken decking is how homeowners get hurt.
A reasonable rule of thumb:
- Wait if it's raining, windy, icy, dark, or the roof is steeper than you can comfortably walk. Contain water inside and call a roofer.
- Consider it yourself only on a dry, calm day, on a low-slope section you can reach safely, with a helper holding the ladder. Even then, a roofer has the harnesses and experience you don't.
- Whoever installs it should extend it past the damaged area and over the ridge where possible, so water runs over the tarp and not under it. Secure it with boards rather than many new nail holes through good shingles.
Photograph the damage before the tarp goes on, because a tarp also hides what the adjuster needs to see.
Finding the source once it's safe
Water rarely drops straight down from the hole. It enters at one point, runs along the deck, rafters, or the top of the drywall, and drips where gravity wins. Start at the stain and work uphill.
Rule out things that aren't the roof
Ask whether the stain shows up only when it rains. If it appears in dry weather, look at plumbing above that ceiling, a bathroom fan duct, or HVAC lines and drain pans in the attic. Those need a plumber or HVAC technician, not a roofer.
Check the attic
With a flashlight, look for wet insulation, dark stains on the underside of the deck, rusty nail tips, and daylight around pipes or vents. Mark what you find with a pencil or tape so a roofer can match it from above.
Flashing, vents, and chimneys
Our roof repair overview covers failures common to 1990s and 2000s subdivisions in the metro, when repair is the wrong call, and permit rules. When the shingles look intact, the details are worth checking: flashing around chimneys and walls, pipe boots, and vents.
Ice dams
Freeze and thaw cycles in Kansas City winters can form ice dams. North Dakota State University Extension explains that heat leaking into the attic, together with poor ventilation near the eaves, drives the melting that forms them. Patching shingles won't stop a repeat if the attic stays warm. See our guide to ice dams on roofs.
| Where water shows up inside | Likely roof source to check | Notes |
|---|---|---|
| Ceiling near a chimney | Chimney flashing or counterflashing, cracked crown | Masonry work may need a mason as well as a roofer |
| Ceiling under a bathroom or kitchen vent | Pipe boot or vent flashing | Also rule out the fan duct and plumbing |
| Wall below a dormer or second story wall | Step flashing, siding, or window trim | Wind-driven rain can enter through the wall, not the roof |
| Near exterior walls in winter | Ice dam at the eaves | Often appears with no roof penetration above |
| Where two roof slopes meet | Valley metal or valley shingles | Valleys carry heavy water flow |
| Spots after a hail or wind storm | Missing or damaged shingles, punctures | Photograph from the ground and call your insurer |
| Under a skylight | Skylight flashing or seal | Condensation can mimic a leak in cold weather |
DIY vs call a roofer
| Task | Reasonable for a homeowner? | Why |
|---|---|---|
| Buckets, towels, moving belongings | Yes | No height, no risk to the claim |
| Photos, video, and a written log | Yes | Regulators in both states recommend it |
| Fans and dehumidifier | Yes, once power is safe | Helps meet the EPA drying window |
| Attic inspection with a flashlight | Usually, if you can stay on joists | A misstep can put a foot through the ceiling |
| Tarping a low-slope section on a dry, calm day | Maybe, with a helper | Fall risk, and a bad tarp can channel water in |
| Tarping during a storm or on a steep roof | No | High fall risk; wait or call a pro |
| Replacing flashing, valleys, or decking | No | Skilled work, and permanent repairs before inspection can hurt a claim |
| Anything near downed lines or a tree on the roof | No | Call the utility and emergency services first |
Sealant smeared over a leak is a common DIY move. Even if it slows the water, it can hide the evidence an adjuster or roofer needs. It also isn't a substitute for fixing the failed detail.
How to vet an emergency roofer in Kansas City
Leaks and door knocks both tend to follow storms. The state line matters here, because the rules differ on each side.
Kansas side
Under the Kansas Roofing Registration Act, enacted in 2013, roofing contractors generally must obtain a registration certificate from the Kansas Attorney General before performing residential or commercial roofing for a fee, with narrow exemptions. State law requires the attorney general to verify registration numbers for the public and keep a public system to confirm certificates. Ask for the number and check it. The AG also notes that state registration is in addition to any local city or county requirements, and it recommends getting at least three written estimates.
Missouri side
Missouri has no statewide roofing registry. In Kansas City, Missouri, contractor licensing runs through the city, so ask whether a contractor's KCMO license is active and check it. Our directory shows KCMO license status for listed contractors. Other Missouri cities set their own rules. Our Kansas vs Missouri roofing licenses page explains the differences.
Red flags after a storm
- Pressure to sign a contract on the spot, before you've talked to your insurer.
- No registration number (Kansas side) or no local license where one is required.
- Wanting to go up on the roof alone. Missouri DCI advises: don't let contractors inspect your home if you're not watching.
- Someone posing as or speaking for an adjuster and asking for money. DCI notes that insurance adjusters will not ask you for payment.
What will it cost?
We don't publish a repair price. Costs vary with the failure, roof pitch, materials, and deck condition. What we can tell you is what a useful quote looks like. It should name which detail failed, what will be opened up, what happens if the deck underneath is soft, whether new material will match, and what warranty covers the repair. A one-line "fix leak" quote gives you nothing to compare.
What not to do
- Don't climb onto a wet, icy, or storm-damaged roof.
- Don't touch wet switches, outlets, or fixtures, or stand in water to reach the breaker panel.
- Don't stand under a sagging ceiling.
- Don't throw out damaged materials or belongings before you photograph them.
- Don't make permanent repairs before your insurer inspects, if you plan to file a claim.
- Don't sign with a door knocker before checking registration or licensing.
- Don't assume the stain is directly under the hole.
How we put this together
This guide draws on primary sources: FEMA's Ready.gov, the CDC, the EPA, the Missouri Department of Commerce and Insurance, the Kansas Insurance Department, the Kansas Attorney General, Kansas statute, and North Dakota State University Extension. Those sources are linked where we use them. We didn't test products or repair roofs for this guide, and we don't rank or recommend any roofer.

FAQ
What should I do first when my roof starts leaking?
Deal with safety first. Keep people away from wet outlets, fixtures, and sagging ceilings, and shut off power to the area only if you can reach the breaker from a dry spot. Then catch the water, move belongings, and take photos before you clean up.
How do I stop a roof leak from inside the house?
You can't really stop it from inside. You can only manage the water: buckets, towels, plastic sheeting, and moving belongings out of the way. The actual fix happens on the roof, after the weather clears, and is best done by someone with the right equipment.
Should I go on the roof to tarp it during the storm?
No. A wet, windy, or storm-damaged roof is a bad place for a homeowner. Contain the water inside and wait for a dry window or a roofer. A bad fall costs far more than a ruined ceiling.
How long do I have to dry things out before mold becomes a risk?
The EPA says to dry water-damaged areas and items within 24 to 48 hours to prevent mold growth. Wet insulation, carpet pad, and drywall that can't dry in that window may need to come out.
What does my insurer expect me to do after a roof leak?
Missouri and Kansas regulators both say to document the damage with photos, take reasonable temporary steps to prevent more damage, and keep receipts. Missouri's regulator also warns against permanent repairs before the insurer inspects, because the claim might be denied.
How do I check if a Kansas City roofer is legitimate?
On the Kansas side, roofers generally have to hold a registration certificate from the Kansas Attorney General, and the state keeps a public way to confirm it. On the Missouri side there is no state roofing registry, so check the city license where one applies, such as a Kansas City, Missouri contractor license.
What causes a roof leak when the shingles look fine?
Often it's a detail rather than the shingles: flashing at chimneys, walls, and dormers, a cracked pipe boot, or valley metal. In winter, ice dams can push water under shingles and show up in a room with nothing above it.
Get two or three roofers to look at it
Once the water is contained and documented, get a roofer to look at the cause. The Kansas Attorney General suggests collecting at least three written estimates, and that's sound advice on either side of State Line. Our directory lists metro roofers alphabetically, with no paid placements, so you can call contractors directly. Our estimate form starts with your ZIP and names the one contractor who would receive your request before you share contact details. If no contractor covers your ZIP, we won't take your details. Sending a request is not a roofing contract, and the contractor pays us for the introduction. It isn't emergency dispatch, so for an active leak, call a roofer's published number. When you're ready, request a roofing estimate and compare it with the others you collect.
