Chimney crown repair deals with the concrete slab that caps the top of a masonry chimney. The crown should slope away from the flue on every side, overhang the brick by about two inches, and have a drip edge cut underneath so water falls clear of the chimney face.

Most crowns we see were never built that way. A lot of them are a thin layer of mortar troweled flat over the top course of brick. Mortar is not concrete. It shrinks, cracks, and lets water straight down into the chimney, where freeze-thaw cycles push the brick apart from the inside. That is often the source of a leak that homeowners blame on the flashing.

For hairline cracks we clean the crown and apply a flexible crown sealant made for masonry. For a crown that is broken, flat, or pulling away from the flue tile, our crew tears it off and forms a new one with a bagged crown mix, a proper slope and a bond break around the flue so the tile can expand without cracking the new slab.

A crown repair is a good time to add chimney cap installation and to look at the mortar below with chimney tuckpointing. Call (833) 583-1301 to book chimney leak repair from the top down.

How a chimney leak job goes

Four steps to chimney flashing repair in Saint Thomas, MO

01

Call and describe the leak

Tell us where the water shows up and when. A stain that only appears in wind-driven rain points somewhere different than water in the firebox.

02

We find the entry point

Our crew checks the crown, the brick face and the step and counter flashing, because a leak at the chimney is not always a flashing problem.

03

You get a plain written scope

We tell you what failed, what we plan to replace and what it costs before any shingle comes off.

04

We fix it with metal, not caulk

New step flashing under each shingle course and counter flashing set into a ground mortar joint. Photos before and after.

Chimney Flashing Repair FAQs

Questions about chimney flashing repair

Questions we hear about Chimney Crown Repair in Saint Thomas, MO.

Call (833) 583-1301
Do I need a chimney cricket?
Building code calls for a cricket on the uphill side of any chimney wider than 30 inches, unless the chimney sits on the ridge. Even on a narrower chimney, a cricket helps if you see leaves piling up or water ponding behind the brick after a storm.
Will you match my existing shingles?
We reuse the shingles we remove when they are in good shape and bring matching replacements when they are not. On older roofs the color may not be a perfect match, and we will tell you that before we start.
Is chimney leak repair covered by homeowners insurance?
That depends on your policy and what caused the leak. Sudden storm damage is often covered, while wear and old flashing usually is not. We photograph the damage and write up what we find so you have something to show your adjuster.
What metal do you use for chimney flashing?
On most asphalt shingle roofs we use aluminum or galvanized steel. On slate, cedar or historic homes we use copper, which lasts as long as the roof. We avoid pairing copper with galvanized steel or aluminum on the same detail because the two corrode each other.
My house has no chimney. Can you still help with a roof leak?
Yes. Much of our work is wall flashing, skylight flashing, vent pipe boots and valley flashing, which use the same methods as a chimney. On homes without masonry chimneys, those are where most leaks start.
