What to Do When Your Roof Is Leaking in a Rainstorm

A roof leak during a rainstorm is one of the most stressful things a homeowner deals with. Water is coming in, the storm is not stopping, and every minute the damage grows. The good news: most of the worst outcomes are preventable if you take the right steps in the first hour. This guide walks through what to do when water is actively dripping through your ceiling, how to limit damage until a contractor arrives, and how to make sure the temporary fix does not undermine an insurance claim or a permanent repair later.

First 10 Minutes: Stop Interior Damage

Before you do anything outside, contain the water inside. Place buckets, large pots, or any deep containers under active drips. Move furniture, electronics, rugs, and valuables out of the path of water. If water is pooling above a ceiling and the drywall is bulging, take a deep breath and poke a small hole in the lowest point of the bulge with a screwdriver. That sounds counterintuitive, but it lets the trapped water drain in a controlled way into a bucket instead of bringing the whole section of ceiling down at once.

Cut Power to Affected Areas

Water and electricity are a serious hazard. If water is dripping near light fixtures, ceiling fans, smoke detectors, or any electrical outlet, kill the breaker for that part of the house. Do not turn the power back on until a contractor or electrician has confirmed the wiring and fixtures are dry. Skipping this step has caused house fires and injuries that dwarf the original leak damage.

Document Everything Before You Move Anything

Take date-stamped photos and video of every visible sign of water intrusion: ceiling stains, dripping points, pooled water on floors, soaked rugs or furniture, water down walls. This documentation matters if you file an insurance claim. Adjusters routinely reduce settlements when they cannot verify the pre-mitigation condition. Two minutes of phone video can be worth thousands of dollars at claim time.

Locate the Leak Source If Safe

Water rarely enters where it shows up on your ceiling. It travels along rafters, decking, and pipes before finding a low point to drip from. If you can safely enter your attic during the storm with a flashlight, look for the highest point where water is visible on the underside of the deck. That is usually closer to the actual entry point on the roof above. Do not go onto the roof during the storm. Wet roofs, wind, and lightning are not survivable trade-offs for finding a hole sooner.

Call for Emergency Response

Once interior damage is contained, call a licensed roofing contractor that offers emergency response. Reputable Bay Area contractors keep crews on call during the rainy season specifically for this. Our emergency roof leak repair team can dispatch same-day for active leaks, typically tarping the affected area to stop further water entry until conditions allow a permanent repair. When you call, be ready to describe the location, the number of leak points, and whether anyone is currently safe in the home.

Safe Temporary Measures You Can Take

If the storm is severe and a contractor cannot arrive immediately, there are limited steps a homeowner can take from inside or near the home without going on the roof:

• Clear gutters and downspouts at ground level if you can do so safely. Overflowing gutters force water back under shingles and worsen leaks.
• Check that downspout extensions are directing water away from the foundation and not pooling against the house.
• Use a wet/dry vacuum to remove standing water from carpets, floors, and any flat surface where it has pooled. The faster water comes up, the less damage soaks in.
• Run fans and a dehumidifier if you have one, to start drying out wet materials before mold takes hold (mold can begin within 24 to 48 hours of saturation).

Do not climb onto a wet roof. Do not try to tarp the roof yourself in active rain. Falls from wet roofs are a leading cause of homeowner injury in winter.

After the Storm Passes

Once weather permits safe roof access, a contractor will tarp the leak area and assess the cause. Common storm-related sources include lifted or missing shingles, failed flashing at chimneys and skylights, clogged or torn gutters that backed water under the roof edge, and pre-existing wear that finally let go under heavy water load. The tarp is a temporary measure. A permanent repair, or a replacement if the damage is widespread, follows once a full inspection is possible. For a broader look at when storm damage points to replacement rather than repair, see our companion article on eight signs a roof needs replacement.

Insurance Claim Steps

If damage is significant, file a claim with your homeowner’s insurance promptly. Most policies have a notification window of 30 to 60 days but earlier is always better. Keep all documentation: photos, video, contractor written assessment, receipts for any mitigation work, and the original cause-of-loss statement. The contractor’s tarp install record and photos serve as evidence of mitigation, which most policies require to maintain full coverage. Our insurance claim assistance team can work directly with adjusters when disputes arise.

Frequently Asked Questions

Can a roofer really come out during a rainstorm?

Yes, reputable contractors that advertise emergency service maintain on-call crews during the rainy season for exactly this scenario. They will not typically work on the roof in active heavy rain or wind for safety reasons, but they can assess, set up interior mitigation, and tarp the roof as soon as conditions allow safe access.

Will my insurance cover the leak repair?

Sudden damage from a storm event (wind lifting shingles, falling tree limbs, hail) is typically covered. Gradual leaks from wear or deferred maintenance are usually excluded. The insurer will want documentation of the cause and the timeline. A contractor’s written cause-of-loss assessment is often the deciding piece of evidence.

Should I tarp my own roof?

Strongly discouraged. Wet roofs are extremely slippery, and even experienced contractors use harnesses and safety equipment. Wait for a professional. A delay of a few hours with interior containment in place is almost always safer than a homeowner falling from a wet roof.

How long does emergency tarping last?

A properly installed contractor tarp can hold for 30 to 90 days depending on weather exposure, tarp grade, and how it was secured. It is a temporary measure to buy time for a permanent repair, not a long-term solution. Schedule the permanent repair as soon as the inspection report is complete.

Can I prevent leaks during storms in the future?

Most storm leaks trace back to pre-existing issues that the storm exposed: aged shingles, failed flashing, clogged gutters, or worn underlayment. A pre-rainy-season inspection in early fall lets a contractor identify and fix these vulnerabilities before they become emergencies. Many Bay Area homeowners schedule annual fall checkups for this reason.

What if mold starts growing after the leak?

Mold can begin within 24 to 48 hours of saturation. After mitigation, if any materials stayed wet for longer than that, have a remediation specialist assess. Insurance may cover mold remediation tied to a covered water event, but coverage is policy-specific. Document everything and get a written cause-of-loss statement from your contractor.
