A roof leak during or after heavy rain is stressful, but most leaks can be managed step by step. Start with safety. Do not climb onto a wet roof, and do not enter an attic or a room where a ceiling is bulging, sagging, or looks as though it might give way. If water is dripping near light fittings, switches, or outlets, turn off the power to that area if you can do so safely and keep clear until it has been checked.
Your first job is to limit damage inside the home while the leak is still active. Place buckets, pots, or bins under the drip, with towels around them to catch splashes. Move furniture, rugs, electronics, books, and anything that can be damaged by water away from the leak. Lay plastic sheeting or towels under the drip area if you have them.

Step 2: Find Where the Water Is Coming From — From Inside
The leak you see inside is not always directly below the problem on the roof. Water can run along the roof deck, a rafter, or insulation and emerge some distance away.
If it is safe to do so, go into the attic with a torch while the leak is active, or soon after. Look for wet or darkened insulation, rafters, or roof decking; water dripping from a specific point, or a wet trail leading uphill; daylight showing through the roof boards; and dampness around a chimney, vent pipe, or skylight. Note where the water appears relative to features you can see from outside. Do not walk on attic insulation or ceiling joists you cannot see clearly, and do not step on decking that looks soft or sagging.

Step 3: Limit Further Water Entry — Only If It Is Safe
Do not go onto the roof during rain, in high wind, or at night. A wet roof is slippery, and a damaged roof may be weaker than it looks. In dry conditions, a roofing professional may use a securely fastened tarp to cover a damaged area temporarily until a repair can be done. This is a job for someone with the right equipment and experience — a poorly secured tarp can blow off in the next wind.

Why Roofs Leak After Heavy Rain
Damaged or missing shingles
Wind can lift, crack, or remove shingles, leaving the underlayment exposed. In light rain the underlayment may hold; in heavy, wind-driven rain, water can get through.
Worn or loose flashing
Flashing seals the joints around chimneys, vents, skylights, and roof valleys. If it is bent, loose, rusted, or poorly sealed, heavy rain can force water through the joint. Leaks that appear near a chimney or a vent are often flashing-related.
Blocked gutters and valleys
Gutters and roof valleys carry water away from the roof. When they are blocked with leaves or debris, water can back up under shingles or overflow into the roof structure. Heavy rain makes a partial blockage much more obvious, because the water has nowhere to go.
Worn underlayment
Underlayment is the water-resistant layer fitted beneath the shingles. It is a second line of defence, not a substitute for intact shingles. As it ages, it may let water through during prolonged heavy rain.
Condensation mistaken for a leak
In humid weather, moisture can condense on the underside of the roof deck or on cold surfaces in the attic, then drip down and look like a roof leak. Condensation is more likely when attic ventilation is poor. An inspection can help tell the difference, because the repair is very different.

Step 4: Arrange a Roof Inspection and Repair
Once the immediate water is contained, arrange for a roofing professional to inspect the roof. Tell them when the leak started and whether it happened during rain; where inside the home the water appeared; whether the leak is active now or only during rain; the age of the roof, if you know it; and whether the roof has leaked before. See signs you need roof repair and roof repair vs. replacement.

Step 5: Dry Out and Watch for Further Problems
After the repair, ventilate the affected rooms and watch the area through the next heavy rain for stains that grow or reappear, a musty smell, or paint bubbling.

FAQs
Frequently Asked Questions
Why does my roof only leak when it rains heavily?
Light rain may not reach a weak point, or the underlayment may cope with small amounts of water. Heavy rain — especially wind-driven rain — puts more water on the roof for longer, and can push water under lifted shingles or through gaps in flashing that lighter rain never reaches. A leak that only appears in heavy rain still needs attention.
Should I call someone during the rain, or wait until it stops?
You can call during the rain to discuss the situation and arrange an inspection. A roofer generally cannot safely work on a wet roof, but they can advise you on containing the water and plan a visit once conditions allow. If water is coming in actively, say so clearly — see emergency roof repair.
Can I fix a roof leak myself with a tarp or sealant?
A tarp can be a useful temporary cover, but fitting one safely on a roof needs the right equipment and experience. Sealant can help in some flashing repairs, but it does not fix missing shingles or damaged decking. For most homeowners, the safer route is to contain the water inside, then arrange a professional inspection and repair.
How long can I wait before getting a roof leak repaired?
It is best not to wait. Even a small leak can damage insulation, decking, and ceilings over time, and moisture can encourage mould. If the leak is active or the ceiling is sagging, arrange help promptly. If the leak has stopped for now, still arrange an inspection soon — the entry point will still be there at the next heavy rain.
