If Your Roof Is Leaking Right Now
Before you go looking for the source, limit the damage inside:
- Move furniture and electronics clear of the drip and put a bucket down.
- If a section of ceiling is sagging or bulging, pierce the center of the bulge with a screwdriver. That drains the trapped water in one controlled spot instead of letting the whole panel come down.
- Photograph the ceiling, the walls, and anything damaged, before you mop up.
- Then head to the attic and start tracing, using the steps below.
If water is coming in faster than a bucket can handle, that is an emergency roof repair call, not a weekend project.
Step 1: Start in the Attic
During or right after a rain, head up with a flashlight. Look for:
- Water trails on rafters or decking
- Wet or matted insulation
- Dark staining on wood
- Active dripping
- Daylight visible through the roof deck
Step 2: Trace Uphill
Water doesn't enter where it lands. It travels along rafters and decking until it hits a seam or low point and drips. Find the wettest spot, then trace the water trail back uphill until it stops. That's your entry point, or close to it.
Step 3: Mark the Spot
Push a wire, nail, or marker through the roof deck at the suspected entry point so you can find the location from the outside. Or measure from a reference like a vent pipe, chimney, or hip line.
Step 4: Look at That Spot from the Roof
Now you know where to look. Inspect that exact area for:
- Cracked or missing pipe boots: the rubber gasket around plumbing vents
- Lifted or torn shingles: usually from wind or hail
- Failed flashing at chimneys, walls, or skylights
- Cracked sealant at penetrations
- Valley issues: torn underlayment, missing shingle interlace
What the Repair Actually Involves
Once the source is known, the fix depends entirely on what failed. This is roughly how the common ones compare:
| Leak source | What the repair involves | Typical scale |
|---|---|---|
| Cracked pipe boot | Lift surrounding shingles, replace the boot, reseat and seal | Same visit, smallest repair |
| Missing or lifted shingles | Replace the affected shingles and re-nail the surrounding course | Same visit if the deck is dry |
| Chimney or wall flashing | Strip back shingles, rebuild step and counter flashing | Half day, higher labor |
| Valley failure | Open the valley, replace underlayment, re-lay the interlace | Half to full day |
| Rotted decking under the leak | Cut out and replace the wet sheathing, then rebuild the roof layers above it | Larger job, price depends on area |
We put the price in writing after the inspection, before any work begins. If the leak turns out to be one symptom of a roof that is near the end of its life, we say that too, and you can weigh it against a repair versus replacement comparison instead of paying twice.
Step 5: Repair or Call a Pro
A cracked pipe boot or single missing shingle is a straightforward fix. Multiple lifted shingles, failed valley flashing, or chimney leaks usually need a professional. Either way, get it fixed before the next storm, small leaks turn into rotted decking and ceiling replacement fast.
If the Leak Started After a Storm
A leak that appears right after hail or high wind usually has a matching mark on the roof surface. Document the date, keep your photos, and have the whole roof looked at rather than just the one spot, because wind and hail rarely damage a single square foot. Our post-hail checklist walks through what to record and in what order.
