What to Do If Your Roof Is Leaking

Water dripping from your ceiling during a storm is one of the worst feelings as a homeowner. Your instinct is to panic, grab a ladder, and try to fix it yourself. Resist that urge. The first 30 minutes after discovering a leak determine whether you're dealing with a minor repair or thousands of dollars in secondary water damage.

Here's exactly what to do, step by step, based on what we see every week responding to emergency roof calls across the Chicago suburbs. If you're not sure yet whether you're dealing with an active leak, check our guide to the warning signs of a leaky roof.

Step 1: Contain the Water

Grab every bucket, pot, and storage bin you have. Place them under every active drip. Lay towels around the base of each container to catch splashes. If water is running along a wall, use towels to direct it toward a container rather than letting it spread across the floor.

If your ceiling is bulging or sagging, that means water is pooling above the drywall. Place a large bucket directly underneath, then carefully puncture the lowest point of the bulge with a nail or screwdriver. This sounds counterintuitive, but letting the water drain in a controlled stream prevents the entire ceiling section from collapsing under the weight.

Step 2: Move Your Valuables

Water follows unpredictable paths once it enters a home. It runs along joists, pools on vapor barriers, and can show up in rooms nowhere near the actual roof penetration. Move electronics, documents, furniture, and anything irreplaceable away from the affected area. If furniture is too heavy to move, cover it with plastic sheeting or garbage bags.

Pay special attention to closets and storage areas directly below the leak. Water damage to stored items adds up fast on insurance claims, and moving things proactively is far cheaper than replacing them.

Step 3: Document Everything

Before you clean up a single drop, take photos and video. Photograph the water coming in, the stained ceiling, the containers catching drips, any damaged belongings, and the exterior of your home if you can see visible roof damage from the ground. Timestamp matters. Your phone automatically timestamps photos, which creates a record that ties the damage to a specific storm event.

This documentation is critical for your insurance claim. Adjusters need evidence of both the cause and the resulting interior damage. Homeowners who document thoroughly before cleanup get significantly better claim outcomes than those who clean up first and call later. For a full walkthrough of the filing process, see our guide on filing a roof insurance claim.

Step 4: Cut Power to the Affected Area

If water is anywhere near light fixtures, outlets, or your electrical panel, go to your breaker box and shut off the circuits for the affected rooms. Water and electricity are a lethal combination. Don't flip light switches in rooms with active leaks, and don't touch any electrical fixtures that are wet.

If your breaker box itself is in the path of water, call an electrician before touching it. This is a genuine safety emergency, not something to figure out on your own.

Step 5: Do Not Go on Your Roof

This is the most important step, and it's the one homeowners ignore most often. Do not climb onto a wet, damaged roof. Storm-damaged decking can be soft and structurally compromised. Wet shingles are slippery. Wind gusts during active storms can knock you off balance. Every year, homeowners are seriously injured or killed falling from roofs during or after storms.

You also can't fix the problem from up there. Roof leaks are notoriously hard to trace because water enters at one point and travels along rafters, sheathing, and vapor barriers before it drips through your ceiling somewhere else entirely. Understanding the common causes of roof leaks helps, but tracing the path requires professional tools and experience. A professional crew with fall protection, experience, and the right materials is the only safe and effective option.

Step 6: Call for Emergency Roof Repair

Once you've contained the water and documented the damage, call a local roofing contractor for emergency repair. Emergency tarping stops water intrusion immediately and prevents further interior damage while your insurance claim processes.

A reputable contractor will tarp the damaged area, inspect the roof to identify the source, and provide documentation for your insurance company. Be wary of anyone who shows up at your door unsolicited after a storm, especially with out-of-state plates. Storm chasers flood Chicagoland after every major hail event, and they're gone before the warranty matters.

Step 7: File Your Insurance Claim the Right Way

Call your insurance company after you've spoken with a contractor, not before. You want professional documentation of the damage in hand when you file. Your contractor's inspection report, combined with your own photos and video, gives the adjuster everything they need to process the claim efficiently.

Most Illinois homeowner's policies cover sudden storm damage to roofs, including the interior water damage it causes. Your policy likely requires you to mitigate further damage promptly, which means emergency tarping isn't optional. It's your obligation under the policy, and the cost is typically covered as part of the claim.

If your claim gets denied or underpaid, you have options. Illinois allows you to request a re-inspection, and you can hire a public adjuster to advocate on your behalf. Don't accept the first offer if the numbers don't add up.

What About Temporary DIY Fixes?

If you're waiting for a crew and the rain won't stop, there are a few things you can safely do from inside the attic. If you can access the attic and see daylight or water entry, you can place a bucket under the entry point and use roofing cement or a piece of plywood to temporarily slow the flow from below. Apply the patch from inside the attic, pushing it up against the underside of the decking.

From the ground level on a single-story section, you can drape a tarp over the damaged area and weigh it down with sandbags or 2x4s. Never secure a tarp with nails driven into the roof surface, as that creates new penetration points. And if you can't reach the area safely from the ground, leave it alone and wait for the professionals.

Leaks After Recent Chicagoland Storms

If your leak started during or after the March 2026 DuPage County hailstorm, you're almost certainly dealing with storm damage rather than a wear issue. That storm produced baseball-sized hail with a 4.8-inch stone measured in Darien. Hailstones that large don't just knock off granules. They fracture the shingle mat, crack decking, and destroy flashing seals.

Storm damage leaks can also appear days or weeks after the event. A hail strike might fracture the mat without immediately creating a visible hole. Then the next hard rain pushes water through the compromised material. If your leak showed up recently and you're in DuPage, Will, or western Cook County, schedule an inspection even if you don't think your roof was hit.

Before you hire a repair contractor, use our 8-point contractor checklist to verify their credentials. Permanent address, insurance coverage, storm certifications, and contingency contract terms are the basics. Skip anyone who can't check those boxes.
