What to Do When Your Roof Is Leaking Right Now: Emergency Guide for St. Louis Homeowners

If your roof is leaking right now, do these three things first: place a bucket under the drip, move electronics and furniture away from the water, and turn off electricity to any room where water is near light fixtures or outlets. Do not get on the roof. Mold can begin growing within 24 to 48 hours of water exposure, so containing the leak immediately is not optional. Emergency roof tarping by a professional costs $300 to $800 in the St. Louis area and is usually reimbursable through your homeowners insurance. Here is exactly what to do, step by step.

What Should I Do First When My Roof Is Leaking?

Your first priority is people, then electricity, then water containment, then documentation. In that order.

Step 1: Protect people. Keep everyone away from the drip area. If the ceiling is sagging or bulging, that is pooled water overhead that could collapse. Evacuate that room. If water is in contact with electrical wiring, outlets, or light fixtures and you cannot safely reach the breaker panel, leave the house and call 911.

Step 2: Kill electricity. Turn off the circuit breaker for any room where water is actively leaking near electrical fixtures. Water and electricity together are a fire and electrocution risk. If you are unsure which breaker controls which room, turn off the main breaker until you can confirm.

Step 3: Contain the water. Place buckets, trash cans, or any waterproof containers under every active drip point. Lay towels or plastic sheeting around the containers to catch splashes. If standing water is accumulating on the floor, soak it up immediately. Standing water causes floor damage and creates conditions for mold within 24 to 48 hours.

Step 4: Release a ceiling bubble. If your ceiling paint is bulging downward with trapped water, place a bucket underneath and carefully puncture the lowest point with a screwdriver or nail. This releases the water in a controlled way rather than letting the entire ceiling section collapse. It sounds counterintuitive, but a small controlled hole prevents a much larger, more expensive ceiling failure.

Step 5: Move valuables. Get electronics, documents, furniture, rugs, and anything water-sensitive away from the leak zone. Cover anything you cannot move with plastic sheeting or garbage bags.

Should I Get on the Roof to Fix the Leak?

No. A wet roof is one of the most dangerous surfaces you can stand on. Professional roofers account for falls as the number one cause of serious roofing injuries, according to OSHA. During rain, wind, or darkness, the risk multiplies. No temporary patch is worth a trip to the emergency room.

Additionally, attempting a DIY repair before a professional inspects the damage can hurt your insurance claim. If you seal over the entry point, the adjuster may not be able to see the original damage, which makes it harder to document the cause and get the full scope of repair covered under your policy.

Your job during an active leak is interior containment. The exterior repair comes after the rain stops and a professional can safely access the roof.

How Do I Document the Damage for Insurance?

Start documenting before you clean up. Your smartphone is the most important tool you have right now.

Photograph everything. The drip point on the ceiling, the water on the floor, the damaged belongings, the ceiling stain, the bulging drywall, any visible damage from outside (use your phone’s zoom from the ground). Take more photos than you think you need. Insurance adjusters review these images to validate the claim.

Keep a written log. Note the date and time you discovered the leak, weather conditions, every step you took to contain the water, and every call you made. Example: “June 15, 11:30 PM. Noticed water dripping from living room ceiling. Placed bucket under drip. Moved sofa and electronics. 11:45 PM, called Family First Exteriors emergency line.”

Save receipts. If you buy tarps, buckets, towels, or a wet vacuum, keep the receipts. Emergency mitigation costs are typically reimbursable under your homeowners insurance policy. Your policy requires you to mitigate damage (stop it from getting worse), and the costs of doing so are covered.

Most Missouri homeowners policies require you to report damage within 48 hours to 30 days depending on the carrier. Call your insurance company as soon as the immediate emergency is contained.

When Should I Call an Emergency Roofer in St. Louis?

Call immediately if any of the following apply:

Water is pouring, not dripping. Your ceiling is sagging or bulging in multiple areas. A tree or large debris has hit the roof. You can see exposed decking or sky from the attic. Multiple rooms are affected simultaneously. Water is near electrical systems and you cannot safely isolate the circuits.

A professional emergency roofer will tarp the damaged area to prevent further water entry, inspect the roof once conditions are safe, document the damage for your insurance claim, and provide a repair or replacement scope. Family First Exteriors provides 24/7 emergency response for storm damage across the St. Louis metro area.

Be cautious of who you call. After major St. Louis storms, door-to-door contractors appear within hours offering “emergency” repairs. Use a local contractor with a permanent address and a track record in the St. Louis area. Family First Exteriors operates from 15009 Manchester Rd, Ste 261, Ballwin, MO 63011 and has been serving St. Louis homeowners since 2002.

Why Does a Roof Leak in One Spot but Enter in Another?

The wet spot on your ceiling is almost never directly below the hole in the roof. Water enters at one point, then travels along rafters, roof deck panels, pipes, and even electrical wiring before finding a low point where it finally drips through. The actual entry point can be 10 to 20 feet from the visible drip.

This is why DIY patching from inside the attic rarely works. You might seal the drip point, but the entry point on the roof surface remains open. A professional roofer traces the moisture path back to the true entry point using experience and, in some cases, infrared thermal cameras.

If you can safely access your attic during dry conditions (not during an active storm), look for water-stained wood, matted insulation, and “shiners” (nails that look frosted or white from moisture). These clues help narrow down the entry location.
