Roof Leaking Right Now? Your First-Hour Checklist

Minutes 0–10: Safety and Belongings

1. Check for electrical risk. If water is near a light fixture, ceiling fan, outlet or electronics, turn off that circuit at the breaker panel. Never touch wet electrical devices.
2. Look at the ceiling. If it is bulging or sagging, keep everyone out from under it. A water-filled bulge can come down suddenly.
3. Move what you can. Pull furniture, rugs, electronics, documents and anything valuable away from the drip. Cover items you cannot move with plastic sheeting or a shower curtain.

Minutes 10–30: Contain the Water

Now focus on keeping the water in one place:

• Place a bucket, trash can or storage tote under the drip. Put a towel in the bottom to reduce splashing.
• Lay towels around the container to catch spray and protect floors.
• If a bulge is clearly holding water, place a container under it and make a small hole at the lowest point with a screwdriver so it drains in a controlled stream rather than tearing open.
• Run a wet/dry vacuum or mop as needed, and empty containers before they overflow.

If you have attic access and can move safely on the framing, put a container under the drip in the attic too, or lay a piece of plywood across the joists with a bucket on it. Catching water above the ceiling protects drywall and insulation below.

Minutes 30–45: Gather Clues About the Source

You do not need to fix the roof tonight, but information you gather now will help the roofer find the leak quickly.

• Note where the water appears and whether it is near a chimney, skylight, vent, valley or exterior wall.
• In the attic, look for wet trails on rafters or the underside of the decking. Water often travels before it drips, so follow it uphill.
• From the ground, look for missing shingles, a fallen limb or overflowing gutters on that part of the roof.
• Check what else is above the ceiling. If the leak is under an attic air handler or bathroom, it might not be the roof at all.

Take photos and short videos of everything, including the drip, the stain, any attic water and visible exterior damage. Write down the time the leak started and the weather conditions.

Minutes 45–60: Temporary Measures and Calling for Help

Inside, your goal is containment. Outside, the safest temporary measure is a tarp, but only when the rain and wind have stopped and the roof is safe to access. In most cases, it is wiser to have a professional handle that. If you are experienced and conditions are safe, our guide to tarping a roof after a storm explains the method.

Then call a roofer. Describe what you are seeing, where the water appears and whether there is visible damage outside. Ask about temporary protection and when a permanent repair can be scheduled once things dry out. Tekton Exteriors handles leak calls through our emergency roof repair service; for a look at how that process works from our side, read about emergency leak repair across Mississippi.

The Next Day: Dry Out and Document

Moisture trapped in insulation, drywall and carpet can lead to mold. In warm, humid conditions, mold growth can begin within 24 to 48 hours.

• Run fans and a dehumidifier in the affected room.
• Pull up wet rugs and move them somewhere they can dry.
• Remove soaked insulation in the attic if you can do so safely, or ask your contractor to handle it.
• Keep receipts for supplies, fans and any temporary repairs.

If the leak came from storm damage, notify your insurance company and share your photos and notes. If it came from age or wear, a roofer can tell you whether a targeted repair or a replacement makes more sense.

Preventing the Next One

Many emergency leaks come from small issues that were building for months: a cracked pipe boot, a clogged valley, a loose piece of flashing or gutters overflowing behind the fascia. A quick inspection each spring and fall, cleaning gutters before storm season and trimming limbs that overhang the roof prevent a surprising number of roof leaks. It costs far less to fix a $20 part in dry weather than to deal with a ceiling in the middle of a storm.
