Water Leaking From a Light Fixture After Rain: What to Do

Water leaking from a light fixture after rain is an electrical hazard first and a roof leak second. From our experience, the breaker comes before the bucket, so shut off the power to that room and call a roofer and an electrician.

If you have water dripping from a light fixture, you may be afraid to touch the switch. That is the right instinct. The light is only the lowest opening the water found. On our leak calls, the real source is most often a cracked rubber boot on a plumbing vent. Below is what to do now, why the water shows up in a ceiling light, and who to call.

What should I do if water is leaking from my light fixture?

Shut off the breaker for that room, keep your hands off the fixture and the switch, and catch the water away from the fixture. Then call a roofer and an electrician, because the roof and the wiring both need a fix.

Here are the four steps we give our past clients on every leak call, in order:

1. Turn off the breaker. Switch off the breaker for that room at the panel. The wall switch is not enough.
2. Stay clear of the fixture. Do not touch the light, the switch or anything wet near them.
3. Catch the water. Place a bucket or tub under the drip without reaching up toward the fixture. Move furniture and electronics out of the way.
4. Call a roofer and an electrician. Call us for emergency roof repair to stop the water. Call an electrician to check the fixture. For the full checklist, read what to do when your roof is leaking.

Do not walk through standing water to reach the panel. If the panel is not safe to reach, stay out of the room.

Why rain comes through a light fixture

Roof water runs along the rafters and pools on top of the ceiling until it finds a hole it can drip through. The opening cut for a light fixture is often that hole, and the real entry point can be several feet away.

When you see water leaking from a ceiling light after rain, the roof is the first suspect. Water coming out of a light fixture rarely starts there. Rubber vent boots typically crack within 8 to 10 years under Florida sun.

A boot is the rubber collar that seals a plumbing vent pipe where it exits the roof. On our inspections, a cracked boot is one of the most common sources we find behind a roof leaking through a light fixture. Our guide on what is a roof boot shows what to look for.

Boots are not the only cause. Our post on the common causes of roof leaks covers the rest. Roof flashing is another one to know; flashing is the thin metal that seals joints and edges on a roof.

Roof leak, plumbing or AC: how to tell

A drip after rain points to the roof, and a drip that shows up when a shower or sink runs above points to plumbing. A drip under the attic air handler points to its drain line instead of the roof.

If you also see a brown ring spreading across the ceiling, our guide to water stains on the ceiling explains the common causes. Some drips start in the attic itself, and our attic rain guide covers those.

Can a leak in a light fixture cause a fire?

Yes, a leak in a light fixture can cause a fire. Water can short the wiring and cause a shock or a fire, so treat the fixture as live until an electrician clears it. The Electrical Safety Foundation International says water-damaged electrical equipment carries a long-term fire risk, even after it dries.

Water in a light fixture is never a wait-and-see problem. Keep the breaker off and keep everyone clear of the fixture. Then follow the steps in what to do when your roof is leaking.

When it is safe to turn the light back on

Turn the light back on only when the roof leak is stopped, the ceiling is dry and an electrician has checked the fixture. Until all three are true, leave the breaker off. Never flip the switch to test a ceiling light leaking water.

ESFI lists lighting, LED drivers, switches and junction boxes among the equipment that needs replacing after water damage. That is electrician work, so we do not give wiring steps here. Once the roof is fixed, read about ceiling water damage after a roof leak to see what repairs may come next.

Who to call: a roofer, an electrician or both

Call both. After rain, the roofer comes first to stop the water, and the electrician then makes the fixture safe. Water leaking from a light fixture after rain needs both trades, in that order, because a repaired fixture under a leaking roof will fail again.

Frequently asked questions

Is water dripping from the ceiling an emergency?

Yes, when the water is coming through a light, a fan or an outlet, or when the ceiling is bulging. Turn off the breaker for that room, keep clear of the area, and call a roofer and an electrician. Our guide on what to do when your roof is leaking covers the next steps.

What if water is leaking through a recessed light?

Follow the same steps: breaker off, hands off, and a roofer plus an electrician on the way. A recessed light sits inside a metal housing called a can, and the can and trim get checked before the circuit goes back on. Water in a recessed light is no different from any other fixture, so treat it as live.

How do I stop water dripping from a ceiling light?

You cannot stop it from inside the house. Catch the water, keep the power off, and get the roof tarped until the repair is done. Read will a tarp stop the leak and how to tarp a roof for the details. Leave the roof work to a crew, because climbing up in a storm is unsafe.
