TLDR: If your roof is leaking during rain, move what you can, catch the water, relieve any ceiling bulge with a small hole, and take photos before you do anything else. Do not get on the roof while it is wet. Call a roofer for an emergency tarp if water is actively coming in. The first hour decides how much damage you end up with.
A roof leaking during rain is one of the most stressful things a homeowner deals with, because you cannot fix the roof until the rain stops. What you can do is limit the damage inside your home and set yourself up for a fast, clean repair afterward. Here is what we tell our San Antonio customers when they call us mid-storm.
Step 1: Protect what is under the leak
Move furniture, electronics, rugs, and anything else out from under the drip. If something is too heavy to move, cover it with a plastic sheet or trash bags. Put a bucket or pot under the leak, and drop a towel in the bottom so the dripping does not splash.
Step 2: Relieve a bulging ceiling
If the ceiling is sagging or you see a water bubble forming in the drywall, water is pooling above it. That pool will eventually collapse the ceiling. Take a screwdriver and poke a small hole in the lowest point of the bulge, with a bucket underneath. Letting the water out in a controlled way is far better than a section of ceiling coming down.
Step 3: Take photos and video
Before you clean anything up, photograph the leak, the water on the floor, the ceiling stain, and anything that got wet. If you end up filing an insurance claim, these photos are the strongest evidence you will have. Note the date and time.
Step 4: Check the attic if you can do it safely
If you have attic access and can reach it without climbing on anything unstable, take a flashlight up and look for where the water is entering. It is often not directly above the ceiling stain. Water runs along rafters and roof decking before it drips. Finding the entry point helps the roofer, and you may be able to slide a bucket under it.
Step 5: Do not get on the roof
A wet roof is the most dangerous place on your property. Shingles are slick, and you cannot see what is damaged. Roofers do not go up during active rain, and neither should you. If water is pouring in and you cannot control it inside, call for an emergency tarp and we will come out as soon as it is safe.
Step 6: Call before the rush
After a big rain in San Antonio, every roofer’s phone rings at once. If you call during the storm or the morning after, you are near the front of the line. Tell us whether water is actively coming in, roughly where, and whether the ceiling is sagging. That lets us prioritize.
What happens next
Once the roof is dry, we come out and do a full inspection, not just a look at the spot you saw. Leaks during rain usually come from one of a handful of places: cracked pipe boots, failed flashing around a chimney or wall, lifted or missing shingles, or clogged valleys. Most of these are repairs, not replacements. We will tell you which one you have and whether it makes sense to involve your insurance.
Frequently asked questions
Can a roof leak be fixed while it is raining?
Not permanently. We can tarp the area to stop water from coming in, but the real repair waits until the roof is dry so the materials seal properly.
Why is my roof only leaking during heavy rain?
Light rain sheds off normally. Heavy rain, especially with wind, pushes water sideways under shingles and into flashing gaps that stay dry the rest of the time. That is usually a flashing or shingle seal issue, and it is very fixable.
Will one leak ruin my roof?
No. One leak is one problem spot. The damage it does depends on how long it goes untreated. A leak caught the first week is a repair. A leak ignored for a season can mean rotted decking and mold.
Does the leak mean I need a new roof?
Usually not. Most rain leaks are localized. We will only recommend replacement if the roof has widespread wear or storm damage that a repair will not solve.
