Roof leaks in one spot and stains the ceiling below

Tell a one-spot leak from a worn-out roof

1. Note when it drips. Water only during or right after rain points at the roof. Water in dry weather points at plumbing or an air conditioner drain line.
2. Press the stained ceiling with two fingers. Firm and dry means a slow or seasonal leak. Soft, sagging or dripping means water is coming in now.
3. Mark the wet spot and measure to the nearest wall. Water runs along the sheathing and framing, so the hole is often several feet uphill from the stain.
4. Stand back on the ground and look at what sits above that spot. Chimney, vent stack, skylight, or a roof-to-wall joint are the usual sources.
5. Scan the shingles from the ground. Count curled, bald and missing patches on the whole slope, not just near the leak.
6. Look in the attic in daylight if there is safe access from a floor. Daylight through the deck, or dark trails down a rafter, marks the entry point.

Hire for the roof itself. Do not climb on a roof to find this, and do not walk a wet or steep slope at all. If a penetration sits above the stain and the rest of the slope looks even and intact, it is a patch. If shingles are curled, bald or missing across full slopes, or the spot leaks again after a repair, price a replacement.

What it costs

Runhome contractor estimates for this job, including the trip and assessment.

Can I do it myself?

No for the roof. Finding a leak means working above the entry point on a slope, and a missed detail sends water back into the same ceiling at the next storm. Roof falls are the reason this one is always a hire, even for a pinhole.

Yes for the ceiling. Stained drop-in tiles lift out and new ones drop in for a few dollars each. Wait until the leak above is fixed, because a fresh tile under a live leak stains again within weeks.

What a contractor will ask you

Have these ready and you skip the back-and-forth.

• What is above the leak: asphalt shingles, flat rubber, or metal.
• When you first saw the stain, and whether it is still spreading or new spots are appearing.
• Whether the room is the top floor directly under the roof, or has another floor above it.
• Whether water actively drips during rain, or the tiles are only stained and dry to the touch.
• Whether the damage is one small spot or spread across a wider section of ceiling.
• What sits on the roof above the stain: a chimney, a vent pipe, a skylight, or a roof-to-wall joint. Say whether a chimney is still in use or abandoned.
• How the roof looks from the ground near that spot: missing shingles, cracked or separated flashing, or intact.
• A wide photo of the ceiling inside, plus a wide photo of the roof above it.

Related questions

Can I just get a patch job on my roof?

Yes, on most one-spot leaks. A roofer reseals the flashing or replaces a few shingles in one trip. Ask for the full slope to be checked on that same visit.

Roof leak in the kitchen, small pin hole leak.

A pinhole still soaks the deck above it every rain. Get it patched, then have the stained tiles replaced at the same visit.

The stain is a few feet away from the chimney, does that matter?

No. Water runs along the framing before it drops, so the stain lands away from the hole. The roofer traces it uphill.

My ceiling tiles are stained but dry, do I still need a roofer?

Yes. Dry and stained means the leak is slow or seasonal, not fixed. It returns with the next driving rain.

There is an old unused chimney above the leak, can it be removed?

Often yes. A roofer can take an abandoned stack down to the roof line and close the deck. That removes the leak point instead of resealing it.
