Do not touch or test a light that is getting wet. Keep people and pets away from the fixture and affected floor, and arrange urgent help from a Licensed Electrical Contractor as well as the person tracing the leak.
Smoke, sparking, a burning smell or other immediate danger means leaving the area and calling 911. A working bulb is not reassurance; the electrical risk comes before finding the roof opening.
Do Not Use the Light as a Test
A fixture that illuminates is not proof that it is safe. Nor does a switch in the off position establish that all wiring in the ceiling is de-energised. Water can be present in parts you cannot see.
The Electrical Safety Authority warns that water contacting electrical systems creates a shock risk. Although its guidance addresses flooding, the relevant precaution applies to suspected water contact with electrical equipment: keep clear and have qualified electrical assessment.
Do not reach through water, stand on a wet floor or approach a wet electrical panel to operate equipment. If safe isolation is uncertain, contact the utility or emergency services as appropriate rather than attempting it yourself. Describe the location of water clearly when asking for help.
Put the Electrical Risk First
The order matters when water is near a fixture or wiring.
Keep clear
Avoid the wet fixture, switches, floor and any unstable ceiling.
Arrange safe help
Use a Licensed Electrical Contractor; call 911 for immediate danger.
Stop the source
Coordinate roof or plumbing diagnosis after safe access is established.
Clear each repair
Electrical suitability and drying of building materials need separate checks.
Keep the Area Clear
Move people and pets away. Do not position a ladder beneath the fixture or work under a bulging ceiling. Avoid placing a container where doing so requires touching wet electrical parts or standing in the affected area.
A safe photograph from a distance can help the trades understand the situation. There is no need to get a close-up of the live drip if access is unsafe. Record when the leak started and whether the water followed rain, a plumbing event or another condition.
Do not puncture the ceiling to relieve water. Concealed wiring and the condition of the ceiling are unknown, and a sudden release can create additional hazards.

Why Water Chooses the Light Opening
A ceiling fixture can be where concealed water escapes, even when the entry point is elsewhere. Water may follow framing or a ceiling layer before reaching the opening. IKO's leak guide explains this separation between entry and exit.
That creates two jobs. The electrical contractor determines what equipment or wiring has been affected and what is needed before use. The roofer, plumber or other relevant trade finds and corrects the source after safe access is established.
A rain-free day does not eliminate the electrical concern. Nor does a roof patch establish that water-contacted equipment is safe. Share the findings between trades so one repair does not accidentally become permission to skip the other.
Dry-Looking Is Not Cleared for Use
Let the Licensed Electrical Contractor determine the required inspection or replacement before equipment is returned to use. A dry cover or an off wall switch cannot answer for concealed wiring.
The ceiling and wet insulation need their own assessment too. Completion has three parts: safe electrical equipment, a corrected water source and suitable recovery of the affected building materials.
