If the stain is next to the chimney or the fireplace is damp, say so on the call. The roofer will look at the flashing first, and tell you if a masonry specialist should look at the rest.
A chimney leak, step by step
Chimneys are tall, exposed and made of materials that soak up water. Rain falls on the top, runs down the sides, and collects at the base where the chimney meets the roof. Each of those zones has a different failure mode, and they are repaired by different people. The details for each are covered on the chimney leak repair page.
| Zone | What to look for | Likely repair |
|---|---|---|
| Top: cap and crown | Missing cap, cracked crown slab | Cap installation; crown repair by a mason |
| Middle: brick and mortar | Crumbling mortar, white salt deposits, damp bricks | Repointing; breathable water repellent |
| Base: flashing | Rusted or lifted metal, dried-out sealant | Re-flash with step and counterflashing |
| Behind: the uphill side | Water collecting against a wide chimney | Saddle (cricket) to divert water |
Checks you can do safely
- Stand in the yard in daylight and look at the top of the chimney with binoculars.
- Check the firebox for dampness or rust stains after rain.
- Look for brown stains on the ceiling or wall next to the chimney.
- Notice whether stains appear after wind-driven rain only.
A damp chimney isn’t something to burn a fire in until it has been checked. The flue can be affected by water damage, and a covered or blocked chimney can send smoke and gases into the house. For urgent water entry around the chimney, a temporary cover may be the first step; see emergency roof tarping.
Flashing is the most frequent chimney leak source, and the technical detail is in roof flashing leak repair.

Does a chimney leak always mean the flashing failed?
No. Flashing is the most common cause, but the crown, cap and masonry can leak too. A careful inspection checks each.
Can I use my fireplace if the chimney leaks?
